The forecasted storm rapidly approached from the west during the daylight hours and there was some rain at sunset. However, by 2200 local time, the sky had cleared and about two hours could be spent observing before more clouds moved over the observatory. Five blazars were observed before the dome had to be closed a little after midnight just before the next band of light rain arrived. The seeing started out at 1.5 arcsec, but was between 3 and 4 arcsec for the last successfully observed target of the night. By 0200, heavy rain reached Mt. Bigelow.
