Cronan Ranch 04-09-10
About 15-20 total observers were there. When we, TAC-SAC, arrived, the Sierra Star Gazers were already there. There were some high thin clouds for the first hour after darkness, but most of it cleared out by 9PM. We stayed ‘till a little after 11PM, when more of the high stuff came in…by the time we packed and left, it started clearing again. The naked eye limiting magnitude is about 5.8 to 6.0 as expected for this site, which is not even 1000 feet above sea level and it proximity to the Sacramento area. Our usual high altitude site has at least 3’ of snow on it.
