Gusty southwest winds continued tonight for the fourth straight night. However, it was a bit more civilized tonight, with peak wind gusts of only about 20 mph. Wetter air moved in as well. The humidity reached nearly 60% during the night; a nice change from the desiccating blasts of air that we've received all week.
As with last night, the sky was photometric and after a promising start, the
seeing degraded to 2-3 arcsec for most of time.
