Solar Imaging Session - December 27, 2011 (Huge Long Dark Filaments Remnants & New AR11388 Sunspot Group)

The sky this morning is partly clear and seeing was fair at the start of my solar observation and imaging session. There is a new possible AR11388 Sunspot Group in the eastern limb and its size looks promising to monitor in the days to come. AR11384 Sunspot Group still has a big main umbral core structure. AR11387 Sunspot Group is very active in its core while exiting AR11382 Sunspot Group is near the SW limb already. AR11386 Sunspot Group is very quiet in its core and has almost the same size as AR11387 Sunspot Group.

As I was about to start imaging in white light wavelength, clouds suddenly start to cover the Sun and this caused a sudden drop on the seeing condition from fair to poor :( I still nevertheless proceeded to image AR11384, AR11387 and AR11386 Sunspot Group up close. Afterwards, the sky totally shut me down thus I wasn't able to image full disk :(
