Our high in Central Texas today was 107F; during my imaging session, it was only 106F. Fortunately, I can set up my solar rig on the deck, focus the instrument, and then go back into my study where I can control the laptop and astronomy gear from my desktop. Air conditioning is the only way to survive this heat.
Nearing the sun’s western limb, sunspot group AR3784 has almost disappeared into the far side of the sun. Groups AR3794, now past the center of the disk, and AR3790 & AR3794 in the southern hemisphere are now more prominent. Sunspot group AR3796 just north and east of AR3792 has a surrounding active plage. Sunspots AR3796 and AR3798 are emerging from the eastern limb.
The solar disk today looks like this:
There are prominences on the eastern limb, and prominences on the western limb as well. Other prominences can be seen in larger instruments. Check EarthSky to see those and other features in today’s solar images from NASA.
