Not enough people appreciate what a great sun we have. In preparation for the solar maximum, I will try to see if this idea has any traction here. I'll even bake some webms. Prove to me that this board is anything more than /r/askscience + retarded delusions + career advice. If not, I guess I'll just go back to looking at the sun alone...

bumping again
I wasn't expecting much of a response to begin with, but I honestly did not think there would literally be zero interest. Can I at least get a free bump from someone posting about stupid shit like coronavirus or the geocentric model while I'm away from my computer?

Attention anons!
Seems that my unchecked digits caused a CME yesterday and I didn't catch it.
G2 mag storm starting tonight (Jan 22 0500 UTC), continuing into Tuesday.
If you have a UPS/voltage controller, make sure it's working. If you don't and you're worried, just unplug any sensitive electronics if you're at high latitudes and make sure you know where a flashlight is :D

Each image is a different instrument on the SDO (+ combination images) and some are annotated. Most of the colorful stuff you're seeing is from the atmospheric imaging assembly (AIA), which measures intensities of various wavelengths of light (measured in A on the bottom left). Let me know if you want to know more :D
The SDO takes images every minute and they are published online. Pic is the most recent image (there is some lag between when the photo is taken and once it is received on Earth and processed). If you need help navigating the SDO website, just ask!

what is the surface of the sun like?
flat from high gravity, or like a massive storm at sea with mountains of plasma?

Great question! :D
In very simple terms, you described it best: like a stormy sea of plasma.
However, your question brings up an important concept; if the entire sun is plasma, where do we define the "surface" of the sun? Generally, the uppermost surface of the convective zone (photosphere) is treated as "the surface" of the sun, as it is the lowermost portion that is visible to us. It looks like boiling water on your stove :)

That's a pretty cool photo. H-alpha?
