Weather Report for February 27, 2017

Luck was running high tonight as a gap between cloud/storm systems moving through the area was almost perfectly timed and lasted through most of the night. Light cirrus and very poor seeing (2.5-3 arcsec) had to be tolerated during much of the first third of the night, but photometry was obtained in earnest after about 2300 local time. Observing had to be stopped twice after 0200 for high humidity and/or clouds. Over 2.5 hours were lost to these episodes. Despite the rapidly deteriorating weather near the end of the night, over 15 blazars were observed. During the last half of the night, the seeing was 1.5-2.5 arcsec.

A major winter storm is set to hit Arizona and with luck, some more data may be collected before the end of the campaign.
