Solar Imaging Session - March 14, 2011 (Huge Dark Filament !)

The sky this morning is partly cloudy and seeing is once again poor. AR11166 Sunspot Group is nearing the NW limb and maybe gone in 2 days. AR11169 Sunspot Group, on the other hand has almost lost all of its small components but its main core have developed further and now more photogenic than before.

But one thing that overshadow both big sunspot groups is the sudden increase the the large dark filament that was visible for the past several days. It is not huge in size and length and is quite beautiful to view in Ha wavelength !!!
