20080221 Quiet Sun

We finally got sunny day, seeing is low at 3/10, transparency like 8/10, better than even last night. Exposure like 1/800s can be used for surface detail, and this is rare these days. Surface activity remains low, and there're a couple of interesting but small prominences around the solar limb, nice view.

1150 (GMT+8), surface detail:-

Telescope, filter, cameras: Borg 45ED II, SM40/BF10, DMK31AF03.
