Weather Report for February 11, 2018


High winds on Kitt Peak prevented observations for the first four hours of the night. After the wind had finally abated enough, spectropolarimetric observations could be made for only three blazars before thick clouds moved over the observatory. After waiting around for another four hours, the clouds finally thinned enough that the final two hours of the night could be used to do some work. During this period, the once howling wind had completely disappeared and the seeing was about 2 arcsec. In total, only about a half dozen blazars were observed for the night.
