Solar Imaging Session - March 13, 2011 (2 New Small Sunspot Groups)

The sky this morning is partly clear and seeing again is poor. Aside from AR11166 and AR11169, there are 2 new small sized sunspot groups on the Sun. AR11172 Sunspot Group can be seen in the Eastern limb while tiny AR11173 Sunspot Group can be seen east of AR11169 Sunspot Group.

AR11166 Sunspot Group continues to deteriorate in size but the structure is still nice to look and image nevertheless, Same goes with AR11169 Sunspot Group which has almost lost all of its sunspot core but its main core is still developing and getting larger and more complex though.

Several large dark filaments can be seen also at the center of the Sun's disk as well in Ha wavelength.
