Weather Report for September 21, 2014

This was truly one of the best nights for seeing during the entire monitoring project. The seeing was usually better than 1 arcsec and often around 0.8 arcsec even through the guider's optical system. The sky was photometric until about 0200 local time when mostly thin cirrus moved through the sky. The humidity was was 80-90% all night long and thick clouds started forming all around the observatory right at the start of morning twilight. Over a dozen blazars were observed, with photometry obtained for most of them.
