Solar Imaging Session - January 4, 2013

The sky this morning is partly cloudy and hazy. I proceeded with the session despite so many clouds passing in front of the Sun :( AR11640 Sunspot Group is huge but is nearing the NW limb already while another nice large group, AR11644 Sunspot Group just entered the NE limb. Several sunspot groups namely AR11642, 11643, 11641, and 11638 are scattered across the solar disk. A huge group of eruptive prominences can be seen in the SW limb. As I was about to finish my Ha imaging, clouds started to get thick and covered the Sun thus I wasn't able to image in white light anymore as I'm late for work already. I hope to be able to image AR11640 Sunspot Group tomorrow before it undergoes WIlson Effect in the NW limb.
