Solar Imaging Session - March 17, 2011 (AR11169 Sunspot Group's Mi Ultimo Adios!!!)

The sky this morning is partly cloudy and seeing is poor again. Nevertheless, when I got to peek into the Coronado PST-Ha, I was surprised to see a huge looped prominence at the NW limb! Careful checking reveals that it came from departing AR11169 Sunspot Group which makes a dramatic exit by producing a huge looped prominence and thus making a rather dull solar view into a very exciting observation and imaging session as it turned out! :)

Aside from the huge prominence, there is another large eruptive prominence that is visible near the NNE limb. The large dark filament that is visible for almost a week and now near the SW limb is still a show stopper amid its reduction in size and activity.

Remnants of AR11172 Sunspot Group can still be seen and new possible AR11174 (not yet assigned but I expect it to more or less be designated that number) is starting to get active in its core near the SE quadrant.

I was able to do any white light imaging again today because of clouds :(

Overall, a nice solar observation and imaging session today amid cloudy skies.
