The tail end of the large batch of clouds that prematurely ended last night's observing
rapidly moved off to the east during the first hour of the night, leaving clear
skies. The seeing was around 2.5 arcsec for the first half of the
night, but at the end of the night was 1.5 arcsec. There were some periods of
very good seeing (1.1 arcsec) during the night.
