Japan launches a big one; China loses one early in flight

China led the day's rocket launches - at least these two - with the 8:00 AM (EDT here, 1200 UTC) launch of the Long March 7A rocket, from the Wenchang Space Launch Site, in the country's Hainan province.  

The mission was short-lived, though. About 85 seconds into the flight, rather close to when other vehicles are going through Max Q, or the maximum dynamic pressure the vehicle will experience, the Long March 7A first stage exploded generating a massive fireball with a cloud of smoke and debris.

The Long March 7A is a vehicle that has flown before, this was the 18th flight, under the name of the state-owned China Aerospace Science and Technology Corporation (CASC). It's important to note that this doesn't mean this particular rocket flew even once because they're not reusable. Every flight is unused hardware. 

The 7A — a variant of China's Long March 7 rocket family — stands just over 197 feet (60 meters) tall and combines the first two Long March 7 stages with a hydrolox (liquid hydrogen and liquid oxygen)-powered third stage capable of launching up to 7 tons to geostationary transfer orbit (GTO).

According to China National Radio, today's launch carried China's Zhongxing-4B spacecraft,, a communications satellite presumably bound for GTO. China's Zhongxing satellites provide telecommunications and broadband internet services and are also thought to provide services for China's military.

An interesting aside to this story is that a test flight of the Chinese Zhuque-3 rocket had been scheduled for Monday evening (presumably US EDT again).

That mission is scheduled to fly from China's Jiuquan Satellite Launch Center, more than 1,500 miles (2,415 kilometers) from Wenchang, at 7:45 p.m. EDT (2345 GMT; 7:45 a.m. local time), and is expected to feature a first-stage landing attempt.

The article these details come from on Space.com was posted this morning (EDT) and at the time there were no updates to details like that, or statements from CASC or any other Chinese source.

Moving to the Japanese launch, that was a fully successful mission. The overview is that the Japanese H3 rocket launched a 10,800-pound navigation satellite to high Earth orbit.

Japan's H3 rocket flew for the ninth time ever this afternoon (Aug. 10).

The H3 lifted off from Tanegashima Space Center today at 3:23 p.m. EDT (1923 GMT; 4:23 a.m. on Aug. 11 local time), carrying the Michibiki 7 navigation satellite aloft.

The two-stage H3 is the successor to Japan's workhorse H-2A rocket, which retired last year after a total of 50 flights. 

The term "navigation satellite" brings GPS or the European Galileo satellites to mind. The Michibiki 7 will be part of Japan's Quasi-Zenith Satellite System (QZSS), a homegrown navigation system that operates high above those satellite constellations in geosynchronous orbit. The QZSS is compatible with GPS.

"QZSS can be used even in the Asia-Oceania regions with longitudes close to Japan, so its usage will be expanded to other countries in these regions as well."
...
Michibiki 7 is carrying a payload for the United States as well — the Situational Awareness Camera Hosted Instrument (SÃCHI), which was developed for the U.S. Space Force by the MIT Lincoln Laboratory. This is the second of two SACHIs to go up on a QZSS satellite; Michibiki 6, which launched atop an H3 in February 2025, hosts the other one. (Yes, Michibiki 6 launched before Michibiki 5.)

"This program will allow the United States to monitor satellite behavior within the GEO belt over a very interesting part of the world," Mark Huber, a technical staff member in the Lincoln Laboratory's Space Systems and Technology Division, said in a statement in December 2020.

"It is also a pathfinder in several ways," he added. "The U.S. team is blueprinting methods to allow sensitive data sharing between the United States and Japan."

Alternatives to the ionosphere

A natural follow up to watching the solar cycle progress, like we did with yesterday's post, is to ask what can we do if the ionosphere just won't cooperate? 

This assumes you want to contact other people or places via ham radio, for some piece of wallpaper or other. I mean, obviously, if you're stuck in a broken down car in the middle of nowhere, you want some sort of phone or high bandwidth connection. 

An answer that's easy to overlook and can work very well on VHF is meteor scatter. Back in April of '24, I put up a post about it, called "When Hobbies Converge or What The Heck is Meteor Scatter?"

Back in the 1950s, hams discovered that the trail created in the upper atmosphere by meteors burning up acted like a radio reflector, as if the ionosphere was enhanced. The effect is most beneficial to VHF stations which typically don't have regular, predictable ionospheric propagation. In the early days, this was done with Morse code, or CW as the hams typically call it (CW for Continuous Wave). Now that we're firmly in the age of computer assisted modulation modes, most people trying to bounce signals off the meteor trails are using a computer assisted mode. The most popular appears to be MSK144 (.pdf alert).

MSK stands for minimum shift keying, a form of continuous-phase frequency-shift keying (FSK) with shift equal to half the baud rate. MSK144 uses message frames of 144 bits and modulation at tone frequencies 1000 and 2000 Hz to transmit channel symbols at keying rate of 2000 baud. The resulting audio waveform can be viewed as a form of offset quadrature phase-shift keying (OQPSK) with individual pulses shaped like the first half-period of a sine wave.

Contacts made via meteor trails in other modes sometimes happen without either end of the contact knowing the connection was caused by a meteor and without using MSK144. Generally, though, your chances of success are better during the named meteor showers that get talked about regularly on sites like Space.com, as well as sites aimed more at amateur astronomers. While the number of meteors per hour varies widely between showers, there's generally one named shower per month, and there's some "sporadic meteor", also called a pebble or something, burning up in the atmosphere even on days when no "shower" is predicted. You'll have more luck looking for contacts in MSK144 mode on the frequencies hams have been using. 

That's why I'm bringing this subject up now. One of the biggest regular annular showers has been ramping up, the Perseid shower, which will (purely coincidentally) peak overnight on Aug. 12-13 under the dark skies of the new moon. It so happens the 12th is the day of the solar eclipse that will be seen to reach totality from a few small areas in east Greenland, western Iceland and northern Spain, so the people who experience totality of the solar eclipse may be treated to a meteor trail or two.  

While sporadic meteors can provide short duration openings, long messages can take excruciatingly long times to send. Meteor scatter also tends to be shorter distances. While multiple hop sporadic E can enable contacts across the US, meteor scatter tends to be more like 1000 miles or less. Occasionally, 1500 miles can happen. That cross-USA kind of multiple hop sporadic E seems to happen less often than meteor scatter, too. 

Still, there have been a handful of grid squares in the SE US that I've worked by meteor scatter easier than waiting for other openings. There's such a thing as the other station being too close, too.

Solar Cycle 25 Update - a bit late

I've been forgetting to update the solar cycle and solar-terrestrial indices for a while. I mean I last updated this last December 29 and that update was even later than this.  

A highlight I've posted on solar cycle updates has been the "Last solar cycles comparison" from Space Weather News, and produced by a group called solen.info. NOTE: the plot is at the first link, not the second (solen.info). Here is the current plot:

It's pretty obvious that cycle 25, 2nd from the bottom (that is, 2nd weakest), peaked a little before the 60 months after cycle start line and the current reading is vertically between cycle 24 (weakest in the last hundred years) and cycle 22 (the black curve) which was in 1986-1996. What's not quite as obvious at first glance is the highest Smoothed Sunspot Numbers (SSNs) of cycle 25 are well above cycle 24, the previous cycle, on the bottom everywhere, but what you can't see on this graph is that cycle 24 had the lowest SSNs in the last hundred years, so cycle 25 has been quite a bit more active than 24 but that's just not saying much. "Hey, we're not the worst cycle in a hundred years!" 

Let's look at Cycle 25's raw data, note the first two vertical lines on the left (2018 and 2020) are still cycle 24:

You'll notice that the absolute peak of cycle 25 occurred during 2024. There were some days with very high solar flux in '24: the highest peak was in August as shown here: each black dot is one month. That peak was a highlight in the last post because that was around the time that I got closer to hearing Alaska on 6m as I ever have. Everything I've ever heard about working Alaska from guys around here is it's pretty much a "once in a lifetime" thing. During that "band opening" I never copied a single letter from Alaska, but a friend in Tennessee copied one 15 second transmission from the Alaskan.

Is there a chance of hearing Alaska down here again in what's left of cycle 25? My guess is that if the current trend holds, almost a smaller and mirror image of cycle 21, then no. The only thing that I think would help the chance of getting Alaska is for a second peak of SSN, equal to or stronger than the previous peak forms. A second peak would completely wipe out the right side (prediction) of the SSN for the rest of the cycle. The only hope would be that the SSN in the time I heard Alaska was well after that peak of the cycle in August. The November/December time frame I heard Alaska in is that short little straight line two dots after the August peak.

Update on efforts to rescue the Swift rescue mission

The last update I saw and posted was this past Monday, Aug. 3, and I wasn't really expecting an update today, but just ran across it. This was linked from NASA Science's page, but that article isn't complete. Space.com has a good report if any of this post makes you say, "whut? WTF are you talking about?" 

It's a progress report. The mission isn't back to the expected conditions, but it's much improved and looking like it could be possible for the mission to meet its objectives. 

LINK originally was in a multi-axis spin rotating at about 9 degrees per second, which resulted in sporadic communications and impeded LINK’s progress toward Swift. Using a series of burns from one of LINK’s electric propulsion thrusters, the Katalyst team now has slowed that spin to about 1.47 degrees per second. Katalyst plans to keep LINK at that spin rate as it proceeds with next steps for the mission. This includes uploading a flight software update in the coming days with new attitude controllers designed to maintain LINK’s stability in its current configuration. These updates would allow LINK to begin maneuvering to align with Swift’s orbit.

As a reminder, the Katalyst LINK mission launched on July 3rd on a mission remarkable in many ways. It's a mission that has never been tried before: the LINK satellite will rendezvous with Swift, attach itself with robotic arms, and boost Swift's orbit back up. For a mission that has never been tried, add to the picture that they were working to an absurdly short schedule compared to virtually all NASA missions. NASA estimates they need to boost Swift before its orbit decays to lower than 186 miles, and further estimate that will happen "by October." They don't provide any input on October 1st vs. the 31st.  

The software updates mentioned above are scheduled to be beamed up to LINK "in the coming days," according to NASA. 

Blue Origin gives possible cause of the New Glenn Explosion

It started making news this afternoon that Blue Origin released an update on their investigation into the explosion back on the evening of May 28, now over two months ago, that destroyed not only their New Glenn test vehicle but much of their pad and surrounding infrastructure. CEO Dave Limp wrote:

Wanted to give an update on the hotfire anomaly investigation. Progress continues. The anomaly originated at the main oxygen valve on one of the BE-4 engines, which was later confirmed by hardware recovery and inspections. Extensive component-level and engine hotfire tests have been conducted to understand the failure mode better and inform mitigations. The path forward is clear. We're making small modifications to the valve that can be quickly retrofitted to existing engines. We’re manufacturing the updated hardware, which will be ready by the end of this month. In parallel, we're working through the remaining fault tree analysis. 

New Glenn is bigger than SpaceX's Falcon 9, closer in size to ULA's Vulcan Centaur.  Like the Falcon 9, New Glenn's first stage is recovered and that has been done successfully twice. The booster stage is powered by seven of their BE-4 engines, and ULA's Vulcan is powered by the BE-4 engines. New Glenn is "designed to launch at least 25 times" and their Blue Moon lander is a critical part of NASA's Artemis lunar landing goals that has been designed to fly on New Glenn. 

While it's easy to appreciate the honesty of CEO Limp's statement published above, a little thing that stood out to me was also noticed by Eric Berger at Ars Technica in their article about this. 

Limp said the company’s path forward is “clear” as it works toward returning the New Glenn rocket to flight before the end of this year.
...
This is a positive update, and the transparency is appreciated. However, it also seems clear from Limp’s statement that the company has not yet identified the root cause of the issue.

If any of you readers work in modern manufacturing companies, you probably noticed that there was no mention of that term in the statement. They're not done until the root cause analysis is done and followed.

Blue's founder, Jeff Bezos, has made it clear he wants to see New Glenn flying again before the end of this year - that has been the talk since all of the airborne chunks of debris hit the ground. Tory Bruno, who had been CEO of United Launch Alliance and is now the president of national security for Blue Origin, made reference to a major development program that Blue is working on, "Blue Ring."

[Tory Bruno] indicated on the social media site X that the next flight of New Glenn could carry the company’s “Blue Ring” spacecraft. “She’s in final build now for a flight this year,” Bruno said Wednesday of the spacecraft.

To inject a little unpleasant honesty, Blue Origin has often come across as a bit slow to achieve various goals they publicly state they're aiming for. They really seem to be focused on getting New Glenn launching again, and it seems possible that this is the effect of bringing in CEO Dave Limp to replace Bob Smith - who also replaced a prior CEO (Rob Meyerson). Now, reporters who have regular contacts inside Blue say they seem like a new company, more focused than ever before, this time focused on getting New Glenn flying before the end of 2026. As Eric Berger puts it, "the long-slumbering giant in the US space industry may finally be waking up."

The Falcon 9 upper stage hit the moon - now the race starts

For the last several days, the web has been abuzz with talk about the Falcon 9 upper stage that was expected to crash into the moon. Much of the buzz has been wrong, or just trying to raise awareness (and funds), such as referring to it as a Falcon 9 rocket, when I think we all know that's just not how F9s work. The booster landed when this upper stage was making orbit (or about 8 minutes after liftoff, if you prefer). 

No, this was just the upper stage of the Falcon 9 that launched two private landers to the moon — Firefly Aerospace's Blue Ghost and Tokyo-based ispace's Resilience — launched to a high, moon-crossing Earth orbit in January 2025. The Falcon used up enough fuel that there wasn't enough to perform the usual maneuver to return to Earth. 

So the company performed a different maneuver to take care of this upper stage, Julianna Scheiman, director of NASA science and Dragon programs at SpaceX, said during a press conference on Aug. 3.

"For high-energy missions, we need to perform a different maneuver to ensure the second stage itself is safe per the appropriate rules and regulations, and so we did that here," she said.

The problem was reality had some other things in mind.

"What has happened is, essentially, a mixture of solar activity and gravity forces have put it on a path towards the moon," Scheiman said. 

The upper stage slammed into the moon at 2:35 a.m. EDT (0635 UTC). Because an exact impact spot wasn't known, they need to work with various other agencies to attempt to learn more, even if just before and after photos of the impact area. 

"NASA’s Lunar Reconnaissance Orbiter and NASA’s ShadowCam instrument on the Korea Pathfinder Lunar Orbiter will look for opportunities to capture before‑and‑after imagery of the impact site," NASA spokesperson Rob Garner, of NASA's Goddard Space Flight Center in Maryland, told Space.com. "Image availability depends on several factors, including the impact location, lighting conditions, and when each spacecraft’s orbit next carries it over the area, which may take a few days to receive any imagery." 

Today's impact occurred on the sunlit side of the moon, reducing chances of hobbyist observers seeing anything. A quick search for news like that turned up nothing. So far the only observatory that claims to be sure they saw the impact is the Lowell Observatory in Flagstaff, Arizona, and reported detections of a lunar plume from the impact.

"We can safely say that we measured a response from the rocket stage impact as a sodium and lithium gas plume a few 10’s of kilometers in size lasting between 5 and 10 minutes after impact," Carl Schmidt told Inside Outer Space's Leonard David.

I'm only vaguely aware of what to expect from a measurement to detect the minerals in the dust column rising from the impact, but the Lowell Observatory provides this photo. I see this as showing two different frequency (or color) lights for sodium and one for lithium. This looks like what I'd expect.

Starship Flight Test 14 looks to be NET August

There just isn't an announced date for it, so I'm assuming Monday August 31. 

FT-14, of course, will be the next flight test after the enormously successful FT-13 back on July 24th. 

The big picture comes from coverage of SpaceX's first ever quarterly earnings report. Starship will achieve orbit and deploy fully operational payloads this time around, according to Elon Musk's talk at the earnings report.

"I'd say things look very good, and that's why we, assuming we receive regulatory approval to do so, will attempt to catch the Ship with the tower on the next flight, which is tentatively scheduled for the end of this month," Musk said during today's call.

The ship, as you know was recovered after its splashdown into the Indian Ocean west of Australia. It's the first Starship to be recovered after one of these flights. While from what we observers could see, the heat shield looked like it survived very well, except maybe to a couple of observers who expressed doubt immediately after the booster recovery, Elon appears to think it looks pretty good. 

"I don't want to jinx it or anything, but I think I'd consider the heat shield problem solved at this point," Musk said.

Both of the launch complexes at Starbase Boca Chica have the (pretty amazing, really) large "chopstick" arms that are designed to both stack the SuperHeavy booster and the ship before flight then to catch both of them in midair after the flight. SpaceX has already famously executed a tower catch of the SuperHeavy booster, but it has not yet tried to catch a Ship. That means Flight 14 could be momentous, provided SpaceX gets permission from regulators to make an attempt.

Flight 14 will also carry up a batch of SpaceX's V3 Starlink satellites, a larger and more capable version of the spacecraft that currently populate the company's broadband megaconstellation. Flight 13 toted 20 Starlink V3s, but Ship deployed them into suborbital space; the satellites will be placed into an operational orbit on the upcoming mission, if all goes to plan, Musk said.

To borrow that quote from Nils Bohr, “prediction is very difficult; especially about the future”. The predictions and reality of the AI "singularity" don't really seem to be in much agreement, and that has to apply in spades to SpaceX's orbital data centers. Still, SpaceX is working to being able to launch Starships at rates that are mind-boggling.

"We expect the cadence of flights to be increasing rapidly, and, probably a year from now, we will be doing at least one flight a day, possibly more," Musk said.

Did you see that the plan for them to expand into the Louisiana waterfront of the Gulf of America appears to be close to being agreed on. The more launch complexes they have to call on, the more realistic everyday launches become.

Update on SWIFT rescue mission

Back last Tuesday, the story broke that the reaction wheel attitude control system on the Link spacecraft sent up to rescue the Swift gamma ray observatory had apparently failed and the Link satellite was spinning out of control. Two of the satellite’s three reaction wheels, used for pointing, had stopped working.

Things didn't look good for the little spacecraft.

... Link was rotating on multiple axes, rendering it unable to maintain a reliable communications link with the ground and complicating efforts to arrest the spin. Two of the satellite’s three reaction wheels, used for pointing, also stopped working. Through sporadic radio contact, engineers discovered a problem with some of the spacecraft’s cold gas thrusters used for finer attitude control.

It's worth pointing out that Link had been working fine, and was out of communication for a while, something that typically happens for many satellites. 

Katalyst’s ground team, working from a control center near Denver, hurried to find a fix and recover the Link satellite. The good news was, the spacecraft’s other systems remained healthy, including its power supply, three xenon-fueled electric thrusters, and the rendezvous and robotics hardware the Link satellite needs to capture Swift.

Remember that, as pointed out last week, Link's electric thrusters are low powered for this sort of task which means they'll need to run them for a long period of time. As of Friday (the 31st), the spacecraft had cut its spin rate in half, from about 9 degrees per second to approximately 4 degrees per second. Naturally, they hope to reduce it much more so they can do the task Link was developed for. 

“Once we are in a more stable configuration, with much more high-bandwidth comms, we’ll be able to use that to downlink all the rich data (about the condition of the spacecraft),” Ghonhee Lee, CEO of Katalyst said. “We do know the states of the reaction wheels and the thrusters and things like that. So our GNC team—guidance, navigation, and control team—has been very hard at work with NASA, essentially remapping all of the control algorithms to be able to have an updated controller ready to go for when we are able to stabilize the spacecraft.” 

The Katalyst engineering team hopes to be able to stop the errant motions entirely and to recover the two reaction control wheels that seem to be completely dead. It would help if they knew exactly what was wrong. They don't really know why the wheels stopped working properly - whether it was a component problem of some sort in the Link satellite or even a collision with space junk of some kind. There are cameras on the Link satellite that can be steered around to look for evidence of what happened. Once the data links are running closer to capacity again. 

It's being considered that the automatic fault detection - a fancy version of turn it off and back on again - could be at least part of the cause.

Whatever the cause, Katalyst’s mission control team lost contact with Link for more than 24 hours after it spun out of control. The satellite then automatically reset itself, just as it was supposed to do.

“This was built-in fault protection logic saying, ‘Hey, if I haven’t heard from anybody in 24 hours, there must be something wrong. I’m going to toggle the power, turn it on and off again,’” Lee said. “It’s just built in. However, that shutdown mode is ungraceful. It basically pulls the plug on everything, and that creates some downstream effects for sensitive systems such as the reaction wheels.

“Basically, there was a big thermal spike that came about as a result of this that over-temperatured the upstream electronic circuits that control the reaction wheels, which ultimately led them to being inoperable,” Lee said.

While busy and this setback ensures they're not quite "there" yet, the Katalyst team is working to complete the rescue mission they contracted for.

“We’re very committed to pursuing this mission,” Lee said. “We’re working side by side with NASA. I just came from a technical working meeting with their controls team, where we’re reviewing the algorithms. It seems like there’s nothing that is preventing us from reestablishing three-axis control of the spacecraft with the remaining reaction wheel, with the remaining thrusters, as well as the electric propulsion.

“It’s not the original mode that we expected to control the spacecraft with, but it seems like we will have sufficient stability and controllability of the spacecraft,” Lee said. “With this, we believe we’ll be able to do the rendezvous with Swift. We believe that we’ll be able to go and do things like the inspection of Swift within a close approach of a few dozen meters. And as it stands right now, we have not made a formal assessment, but we believe that a capture of Swift, an attempted capture of Swift, is very much in the cards.”

Just like that, it's August in Central Florida

I'm not saying that because of changing the page on the calendar. From the feel of being outside, it has been August for a few weeks. Heck, I know a guy who has a lawn service business and he was saying it has been full tilt summer since about day 1: the solstice back on June 21.  

A sure indicator is when the UV Index says 11 on a scale of 1-10 and uses the description, "Potentially Fatal in one hour." We know that's aimed at visitors to the area who aren't used to it and don't pay much attention.

There are many places where folks look forward to summer; it's time to go outside - maybe for the first time in months, enjoy warm, glorious days; garden, bike, picnic; maybe enjoy a book while lounging on the beach. Songs like Nat King Cole's classic "Lazy, Hazy, Crazy Days of Summer" come to mind.

That's not here. Here, summer is something to be a bit more reserved about. If you live here, you can keep up with your regular life. If you were from a moderate place, not used to our heat and humidity, running or other outdoors activity could conceivably kill you. August marks the Dog Days of Summer; everything outdoors slows down. Fishing slows - sure the fish have to eat, but they become more active after dark. Animals are more sluggish. Ordinarily, it can be nasty here from about mid-July to almost the middle of September. The worst of it is August. 

The Minnesotans for Global Warming cherish the summer and endure the winter. Here it's the opposite. 

When we first got an HDTV around 20 years ago, Mrs. Graybeard and I naturally spent much of our TV time searching out HD programming.  One of the first movies we watched was "The Chronicles of Riddick". You have to understand this is not even particularly good scifi. It's a fun movie to watch, it's a visual treat, it's a fantastic display of special effects perfect for HD, but don't pay too much attention to the story. To quote a review (long gone from the net), "Furyans, Necromongers, Elementals, The Underverse, the Threshold...it so clearly wants to be epic that it forgets to tie all of these disparate worlds, universes and civilizations into a coherent story. (Director) Twohy clearly makes the mistake of not realizing that there is a huge difference between being grand and being simply confusing and the more ideas that are introduced, the more lumbering it becomes…"

We still watch it on the rare occasion when we run into it.

A large portion of the movie, and one of the longest action sequences, takes place on the planet Crematoria (many of the names in the movie are that cheesy).  Crematoria is a planet that has a tremendous temperature variation (probably an impossible amount) with daytime temperatures of 700F and night time temperatures 300 below zero. When the sunrise terminator sweeps through, the force of the heat gales that come with it is literally enough to blow you apart, disintegrating flesh and blowing pieces off until you die. There's a scene where a character (Purifier), a Furyan like Riddick, sacrifices himself by walking into the sunrise terminator and self-immolating. That's him trying to stand up to the gales while being set afire and having pieces of burning flesh blown off him.

The first time I saw that scene, it reminded me of the time we decided to do a long bike ride on July 4th (I think it was a hundred mile ride, but for sure it was a virtually all day ride). I mentioned it to Mrs. Graybeard who said, "sure, we've been out on days like that."

The National Weather Service publishes charts for heat index that show the amount of danger from the combination of heat and humidity.  This is one of their charts.  I've drawn a box around the typical morning conditions here.  This morning, when I was doing some work that required I go outside for a a little while, Weather Underground was reporting 86 with a "feels like" temperature of 96.  That's just about dead center of the black rectangle I added. In the afternoon, it pushes farther into the orange, maybe red.   

 

And that's what life here is like for August or maybe from Mid-July through Mid-September. Stay out of the sun. Do your outdoor activities near sunrise or sunset. Don't expose bare skin to the sun any longer than necessary - and even then, use sunscreen if you need to be out when the sun is intense, say from 10 AM to 4 PM. A protection factor (SPF) of 3 million is adequate. Without air conditioning and mosquito control, a technological civilization could not exist here.

Oh, and for those greenies and others pushing the idea that Americans are lazy for having air conditioning because they don't do that in Europe. Our latitude is well south of Europe, like toward the south end of the Sinai Peninsula. Sharm el-Sheikh airport is just a few miles south of our latitude. All of Europe is well north of us. 

Ran across a fun special events ham station last night

My usual hangout in ham radio has tended to be six meters, (50-54 MHz, and the first VHF band in the USA) and the last handful of days 6 has pretty much done one of its "oh, fuggedaboutit" intervals and nothing has been copyable around here. So last night I did one of those things I tend to do when 6 bores me out ofmy mind and dropped down to HF to see if there was anything going on. It was around 10PM here, so 0200 to around 0230 UTC.  

Dropped to 30m. Heard nothing new. 

Dropped to 80m. Likewise. 

Figuring 40m was likely to be the busiest/most crowded but with the same "nothing new" picture, I went up to 7.074 MHz. Very surprisingly, 40 not only wasn't as busy as I frequently find it, but there were a few stations that my copy of the JTAlert software told me I had never worked on 40. I worked three countries for the first time on 40 but that's not the story. The story is that one of them was a special event operation using the call sign GB64MOD. If you're familiar with the ham web site QRZ.com, this is what you see when you look up that call.  Here's a reduced copy of just one of the graphics on that page:

Their QRZ listing says they have a special web page for this event here. It adds this narrative:

GB64MOD ham radio special event station - Celebrates the spirit of the Mod movement through Amateur Radio.. classic British Culture modern communications with fellow Mods, Ham Operators and Shortwave listeners around the globe!

Now, let me tell you why I'm emphasizing this. While I remember much of the "MOD" music, certainly The Who, and Small Faces that they make buttons for in that graphic, as well as many more, that's not what I'm seeing here. What I'm seeing is more evidence for the movement that says "this is why we were called GREAT Britain" with the implied celebration of being Great and not a place that should be wiped out by the suicidal embracing of immigrants who are wiping out the British culture and society.  Which leads to thinking, "we can be GREAT again and we should work at that." Notice there's nothing explicitly leaning in that direction on the website; just a reminder of those days for those who loved them. Make of it what you will.

If you're unfamiliar with special event stations like this they happen quite frequently. The biggest regular events these days are Parks On The Air (POTA) and Summits On The Air (SOTA). People collect certificates and QSLs from activities like all of these.
