Weather Report for February 2, 2013

Observing campaign 47 starts off with a usable night at the Bok Telescope on Kitt Peak. Light cirrus clouds were present throughout the night, limiting attempts at photometry. After a brighter-than-third-quarter moon rose, conditions became even more challenging. Over 15 blazars were successfully measured for polarization. The seeing varied between 1.2-2 arcsec. The cloud cover moving in from the southwest is unfortunately expected to be much more extensive during the next few days.
