AR1476 and her “children” on the face of the Sun. Photo by James Guilford.

Sunday, May 13 dawned reasonably clear and so, with cloudy skies anticipated, a few rushed observations were made of our Sun. AR1476 continues to dominate the solar disk through it has been joined by several smaller but notable sunspots. A CME was Earthbound and expected within a few hours with minimal effects expected. Also visible in this photo are granulation and other disturbances in the solar atmosphere. The photo above was made by CAA member James Guilford: Canon EOS 50D: ISO 400, f/8, 1/1,250 sec., 400mm, AstroZap white light film solar filter, May 13, 2012 at 9:15 AM.
