The Sun on February 9, 2013

Although there are no actively-flaring regions on the sun at the moment, the current active regions show interesting structures in H-alpha.  I also captured some long filaments and a loop prominence. Each image was captured with a PST/SolarMaxII and a modified Microsoft Lifecam.  1000 frames were captured for each image and the best 200 frames were stacked and processed (Registax 6).  Final finishing was done in Photoshop.
Active regions and filaments--AR 1665 and 1670 are particularly prominent
