Weather Report for January 25, 2015

A difficult night with a lot of thick cirrus to contend with that streamed into southern Arizona in advance of a coming storm. Thinner patches of cirrus and occasional holes just allowed spectropolarimetry of less than 10 of the brighter blazars. Photometry was out of the question. Seeing hovered around 2 arcsec when stars could be seen. The forecast is for much worse conditions for the next two nights as the wet, warm storm will be nearly centered on Kitt Peak.
