Weather Report for November 14, 2015

An excellent, photometric night. The seeing was quite good during the first 2/3 of the night (1-1.5 arcsec). It deteriorated to 2-2.5 arcsec during the last few hours. Over 20 blazars observed.

It is hard to believe that by the start of tomorrow night, the weather forecast has overcast skies with a fair chance of rain before dawn. Two strong storm systems, one from the south and one from the north, are expected to converge over Arizona and make things difficult for the next few days.
