More Wow! from SDO

On second thoughts, I'm putting it behind a cut, because it is rather big. But it's pretty, and dynamic, and very, very pink. Which is an artistic choice on the part of the scientists; I suppose eventually we'll get used to 304 Angstroms being magenta instead of the black-body orange EIT has been using. The pink frame was my choice, though.

Found via Facebook. (Seriously, if you like this kind of thing and can stand Facebook, it's worth friending Little SDO over there. Only then you have to be a bit careful what you share with friends-of-friends, because zie has a LOT of friends.)

These movies look really freaky to me, because the granulation movements on the surface of the Sun look so much like the seeing-induced swimming when you look at the full Moon through a small telescope at that sort of magnification ... I have to keep reminding myself that it's convection on the Sun rather than in the intervening atmosphere.

Have the researchers got a pet name for the bit of fluff in the two-o'clock position just off the edge of the disc yet?

That reminds me that the five-minute oscillations that we use for helioseismology were originally considered as a nuisance "noise" effect.

If they've named the various bits of crud on that CCD, they haven't shared the names with the public yet.
