Another relative clear and sunny morning with steady skies.  If the Astronomical League’s Solar Ha program called for a Dinosaur Prom, today was the day to observe.  Some nice proms at the Western limb, and the top one resembles a Dinosaur climbing the Sun .  The sun’s activity is down again with only 4 regions with a total of 16 spots covering an area of 480 millionth and to top it off, only 4 C-Class flares in the last 2 days.  Today a full disk image with a closeup of the west limb regions as well as the Dinosaur Prom and a close up in WL/continuum of AR2305.
