Weather Report for July 6, 2013


A very slow night. The first two hours were lost to clouds. In the next three hours, only two blazars were completed through cirrus, which became thick enough after 0100 local time to force a dome closing. At just before 0300 the sky improved and roughly a half dozen blazars were observed to finish the night. The sky was never photometric and like the three previous nights, little photometry was obtained. The seeing was around 2 arcsec early in the night, but was excellent during the final 1.5 hours (1 arcsec).
