Coolest Pic of the ...

Coolest pic of the ... day?  Week?  Month?  Sunspot group 1429, the source of the X-class flares a week or so ago.  From Averted Imagination
False color, Hydrogen Alpha emission image, with brightness negative:  lighter colors are lower radiation; darker colors are more intense H-a sources.  Looks like some sort of alien face with an under bite, doesn't it? 

This made the Astronomy Picture of the Day last week. 

Thing is, this guy is an amateur.  His gear is high-zoot, but it's all amateur-class gear.

I'm the same with my radio gear, but I'm still an "Amateur" radio operator!
