Weather Report for October 26, 2014

A complicated night for weather, but at least a lot of observing could be accomplished. The first couple of hours of the night were marred by mid-level clouds. These clouds formed, dissipated, and moved over the observatory with maddening rapidity. The sky was mostly clear by 2200 local time, but another shorter interval of clouds had to be endured around midnight. The humidity rose steadily from 61% to 89% by morning twilight. The seeing was an unremarkable 1.5-2 arcsec during the first half of the night and afterward improved to 1-1.4 arcsec.
