Solar activity is finally picking up again after a spell of near spotlessness on our star. Despite fine weather country wide I was away from home and unable to get any serious imaging done. I did manage to catch this double disk before the sun slipped closer to the horizon and into the trees. With another large active region just rounding the limb solar astronomers can expect to see plenty in the days ahead, and as we head towards the end of the week then also the chance of auroras also increases!

Latest data released by NOAA shows solar cycle 24 really isn't living up to expectations. Cycle 24 was always predicted to be less intense than cycle 23, but this november batch of data shows if anything since early 2012 activity has actually been falling off. To date there is very little on the near side of our star and the STEREO spacecraft shows there is very little on the far side of the sun. So, what happens from here? Short of an upturn in activity it would appear that this current solar cycle has peaked early and a steady decline is now in effect. However, sunspot numbers are notoriouslly variable and could show an increase as we head into 2013. Really all we can do is monitor things and see what happens!

Our star was at its most photogenic at this wavelength today, though, it has to be said there isn't much going on in the grand scheme of things; very small active regions, very small spots, but the best things were happening with the filaproms today, of which there were numerous small ones aswell as the large one at the solar south pole.
This was taken with the DS40 @ f10.5 with the DMK31 camera, stacked in avistack 2 and post processing done in photoshop CS4.
All todays disks were taken at 420mm focal length using the DMK31. I had to be quick as the sun was nearing the trees and I only have a very brief observing window this time of year!
