I observed the sun in hydrogen alpha both yesterday and today and was able to make sketches both days. You will see that the activity is very similar from yesterday to today, with the features moving a bit to the west from one day to the next. (Note that my North and West compass points are estimations, and not actual measurements).

Solar Dynamics Observatory's Atmospheric Imaging Assembly which is now posting real time solar data. The picture is reversed est to west from my sketches. In it, you can see the active regions and some of the filament structure that I observed in hydrogen alpha.
Jim Ferreira of Livermore, CA took this impressive photo sequence of an eruptive prominence just before sunset yesterday. Click on the image for the full size! Jim is an accomplished astrophotographer and I would recommend you visit his website by clicking on his name above. He uses Stellarvue telescopes for much of his work, which is the same company that produced my 90mm triplet refractor and two of my previous scopes.
