We continue to get sporadic solar activity, with several sunspots and flares recorded during November.

Gema Araujo took these images on November 13, 2006 in both white light and H-Alpha of active region 10923. Through her dedication, skill, and great observing location, Gema is compiling one of the most complete catalogs of (almost) daily solar drawings and photographic images. http://astrosurf.com/obsolar/

Bill Wilson has created an interesting program to calculate the length of a sunspot group from simple timings during visual observations. Its created as an Excel spreadsheet and is available at the link below. Now all we need are some big groups to measure. http://www.aavso.org/observing/programs/solar/solarsoftware.shtml

It is with sadness we report the passing of Alan H. Shapley on October 20 at age 87. Alan was instrumental in developing the AAVSO American Relative Sunspot Number (RA) in the mid 1940's. He was Director of the NOAA Geophysical Data Center in Boulder, Colorado from 1970 to 1981 and the son of Harvard astronomer Harlow Shapley. A fuller text of his career and his contributions to science and the arts can be viewed at: www.aavso.org/observing/programs/solar/shapley.shtml
