Solar Imaging Session - October 25, 2011 (Huge Eruptive Prominence & Hook Shaped Dark Filament !!! )

The sky this morning is clear so I started observing and imaging the Sun as I wake up. There is a huge spike like eruptive prominence that is visible in the eastern limb! One of the the biggest in the past months :) Together with AR11330 Sunspot Group, they form a beautiful pair in the eastern limb :) There are 2 new sunspot groups on the Sun today but they are very small with AR11331 near the edge of NW limb while AR11332 Sunspot Group can be seen in the NE limb above AR11330 Sunspot Group.

AR11324 Sunspot Group continues to decay fast but is still very big in terms of area. AR11330 Sunspot Group has a beautiful dual umbral & penumbral core structure that is worth imaging and observing. Since the sky in the early morning was good at around 3/5 , I can see some solar granulation on the Sun's surface.

AR11324 and AR11327 Sunspot Groups are also starting to decay and becoming dull to view :( There is also a very beautiful hook shaped dark filament above AR11324 group. It was almost straight line the past few days ago. Also another nice big dark filament can be seen soaring near the new AR11332 sunspot group.

Seeing started to deteriorate a bit at the end of the Ha imaging session and deteriorated further after I imaged AR11330 Sunspot Group :(

Overall, it was a very good solar imaging session and I'm looking forward to another fruitful session tomorrow and hope the eastern huge eruptive prominence will grow further :)
