1st half observing specialist: Karen Gloria
	The telescope was opened at 23:00 after a night of clouds and wind.
Karen had nothing special to report.
2nd half observing specialist: Camron Hastings
	I took over with everything running smoothly, as usual with Karen. The
seeing was atrocious at 2.5-3.0" until about 00:35, when it clouded up
again and we closed. We opened again at 04:40. It remained clear for the
remainder of the evening with poor seeing. It never averaged out as well
as the focus images showed. Usually 1.8-2.5".
