Weather Report for November 17, 2015

By the time it finished with Arizona, last night's storm system put two inches of icy snow on the ground at the observatory. There were light snow showers until well past midnight. The last three hours of the night were clear, but there was too much danger from snow on the dome being blown onto the primary mirror if the dome was opened. Tomorrow night's weather forecast is for clear skies and with luck, Campaign 77 will end with a good night.
