I joined Tony Donnangelo and his Takahashi FS-102 apochromat briefly on a chilly Saturday morning (~14:35 UT 2003/1/18) for our first H-alpha solar observing session of the new year. The sky was quite clear but the seeing was nothing to brag about. We first used Tony's Lumicon Solar Prominence Filter with a 12mm Tele Vue Nagler type 4 (68x), a 9mm Nagler type 6 (91x), and a 5.2mm Pentax SMC XL (158x). A fairly large but limb-hugging prominence was visible on the trailing limb. On the opposite limb a prominence in the shape of a thin arc was rather striking.
After a bit we went to a Baader AstroSolar white light filter and the 9 and 5.2mm eyepieces to view the spread of moderately large sunspots such as 250, 254, and 258.

Chance favors the prepared mind.
