Description

WOW! What a sunspot group!! It's so huge you can see it with just your eclipse glasses
This is AR (Active Region) 3664 shown here, which has a total of 81 sunspots. It is producing a bunch of solar flares, including one as high as X2.2 this morning between 8:45-9:36 AM UTC. (For more on solar flares and what the class numbers mean, see https://www.space.com/solar-flares-effects-classification...)

I've got it represented in two ways here: the first is a single exposure time (0.35 ms) where I brought up the background so you could see the giant prominence. The second image is two different exposures (0.35 ms and 10 ms) composited together. Inverting the short-exposure solar disk image usually looks better for this kind of image, which is what I've done here, so the sunspots appear as bright spots instead.
