Weather Report for July 26, 2016

The monsoon took a break around Kitt Peak tonight. One large storm developed just west of the mountain in the afternoon and tracked to the northwest through evening twilight. The clouds from this disturbance prevented several early evening objects from being observed. The sky improved and nearly 20 blazars were observed and plenty of photometric data were obtained. The seeing started out at about 2 arcsec, but by midnight it stabilized to under 1.5 arcsec.
