Solar Observation (August 22, 2009) new
      #3290095 - 08/23/09 09:30 PM Attachment (6 downloads)

I was visiting a friend who owned a Coronado PST solar telescope (1.6" F/10 refractor coupled with a hydrogen-alpha filter). The daytime sky (August 22, 2009 at 17:30 U.T.) had some intermittent cumulus clouds but we decided to take a look at the Sun. My friend had told me that the Sun has not been exhibiting any type of activity over it's surface (including prominences). We turned the PST towards the Sun and were greeted by no less than five prominences over the solar limb! It was exciting to watch these prominences at different magnifications (33-52x). I noted loop, Y-shaped, filament, and bridging prominences. It was fun watching our nearest star.

Below are detailed sectional sketches of the prominences I noted over the Sun as described above. They were all very interesting to study.

Carlos,

You have been very busy as of late. This is a tremendous whole sun sketch and group of close ups. Your sketch work is outstanding.

Frank and Tommy,

Thank you for your compliments on my H-alpha solar observation. It was fun obseerving the Sun once again. I was fun to be able to see the prominences over the solar limb. Hopefully the Sun will exhibit more activity in the future. The best of luck in your own observations.

Carlos
