It is supposed to be clear but I can are a deck of stratus clouds off to the SW. The temperature hasn't changed much since last night but without the wind it almost feels warm sitting there in the Sun.

I had planned to get up at .530 EST to go out and photograph the last quarter apogean Moon but slept through the night and the alarm going off right next to my ear. It is a good thing I made those insurance pictures yesterday morning – if they turn out.

The group is over near the foreshortening zone. I can see a little but of penumbra. The central spot is still large and round.
Every day when I look up the Sun latitudes and longitudes I see the CR listed twice, once for the center of the sun and once for the sunspot location. They have always been the same number
