                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Barentine
 Stayed closed longer than usual at the beginning of the night to allow
Paula to get some dome cals with DIS.  Around 21:30 the wind calmed and
swung to the east, bringing the usual seeing degradation, but this
resolved within about two hours as the wind calmed once again.  The rest
of the night was clear and quiet, the seeing relatively steady in the
neighborhood of one arcsecond.
