Solar Imaging Session - April 5, 2012 (Huge NE Dark Filaments !!!)

The sky this morning is clear and seeing condition is also very good. With a 5 day holiday break, I was very relax and did my solar observation and imaging at a nice pace. The main feature for today's solar session was the long dark filament in the NE quadrant which still haven't snap till now. The huge hedgerow prominence visible yesterday at the SW limb is still visible but has already disintegrated a bit. The other big eruptive prominence in the NW limb is still big and has maintain its size.

AR11450 Sunspot Group is still large but very quiet as well as the other remaining 2 sunspot groups namely AR11452 and AR11453 Sunspot Groups.In white light wavelength, I couldn't see AR11453 anymore despite it visible remnant in Ha wavelength.
