Solar Imaging Session - January 30, 2011 (AR11150 Sunspot Group with Large Eruptive Prominence and Dark Filament )

The sky this morning is fair and seeing is just ok. AR11150 Sunspot Group continues to grow and develop its structure but is till a small fair complex group. In Ha light, the group shows some good solar activity inside its main core. The remnant of the huge eruptive prominence last January 27th can still be seen and is starting to collapse back to the solar limb after its major eruption last Jan 27th. The large dark filament near the NE quadrant has disappeared.

Another sight interesting to view on the Sun in Ha on the other hand is the emergence of a new huge dark filament that is visible in the NW quadrant. This is interesting to monitor as it might still extend more in length in the days to come. Inconspicious small AR11151 Sunspot Group has already disappeared into the NW limb.
