October Clear Spell Continues

Improved Seeing

On October 19th, one day after my previous observing session, seeing conditions were much improved. This time it was a bit warmer, with temperature ranging from 50 to 53 degrees and only a light puffy breeze. There wasn't a cloud in sight. Seeing was good enough to see pointed spicules on the solar limb. These spicules were smeared and blurry during the previous day of poor seeing. 

On this nearly perfect day there were no prominences around the edge of the Sun. But sunspots and filaments on the solar disc showed up nicely in the following 21-panel mosaic reduced to one third of the original size. (Click on the images for a larger view.)

The inverted version of the previous image highlights filaments.

The two major sunspots are 2436 on the left and 2434 on the right in the next closer view.

Near the end of my session I captured sunspot 2434 with a 2000 frame video and stacked the best 100 frames to produce the following image.

Interesting swirling structure and filaments surround the sunspot.
