Hold on to your eyepieces.

There is major activity on the Sun at this time. A whopping thirty-one sunspots (most of them tiny) are the accompaniment to eight Active Regions! We now have ARs 2906, 2907, 2908, 2909, 2910, 2911, 2912 and 2913 available to view. I sketched as much as I could, as quickly as I could, as the Sun was getting quite low. My sketching lasted from 3:16pm to 3:24pm and the sight was excellent with a 25mm in an Orion Skyquest Dobsonian--yielding 48x.

All those interested who can safely do so should attempt a view of this wonderful collection of spots and plage within the next twenty-four hours. The Highland Road Park Observatory will be open to the public on Thursday the 23rd from 11am to 1pm.
