Weather Report for April 17, 2013

What looked to be shaping up as the third photometric night in a row to finish campaign 49 turned into a surprising disappointment. Only 2 hours into the night, and with very good conditions during this period, a thick cloud cap quickly and unexpectedly formed over Mt. Bigelow and ended the night and a successful campaign nearly entirely devoted to following Mrk421 during its VHE "mega-flare". This weather event was not foreseen by the forecasters. Seeing was 1.5 arcsec while data were taken.

SPOL will now be packed up to go back to the Bok Telescope for the May campaign.
