February 25, 2016: Brief solar session


Recommended Posts

I managed to find a gap between storms and look at the sun in H-alpha today over lunch. It took a bit of time to sort the tuning out, but once sorted the view was very detailed. The long straight prom in the south-west is marching inexorably towards the limb as the sun rotates, and the semicircular filament is already quite close to it. North-west of centre there is still a dark, complex filament, with a smaller, more transparent one to its south. Trailing these two filaments is a curiously disturbed area on the disk some way to the east. Two further plage areas can be seen, with attendant filament further east and southwards. Clouds then threatened rain and hail once more, so I had to stop. A brief session, but rewarding.
