Weather Report for February 17, 2015


A strange night in that Mt. Lemmon, which is only about 5 miles west of Mt. Bigelow, was in a cloud cap for nearly the entire night. The sky was mostly clear over the Bigelow observatory most of the night, although about 1.5 hours was lost to clouds starting a little past 0200 local time. Typical of this campaign so far, the seeing was abysmal. At best, the seeing was about 2.5 arcsec, but more often it was worse than 3 arcsec. Over a dozen blazars were observed successfully.
