                ------------- ACTIVITY LOG --------------
 1st/2nd Half Observing Specialist: N.C. Hastings
 DIS engineering went until about 18:30, but I opened at 17:00 to begin
 cooling the dome. I actually saw a spectrum from the red DIS camera
 tonight, looks GREAT. George Wallerstein started the night with the
 echelle. Good seeing, lots of cirrus though. No problems encountered.
 The GFP is on the vacuum pump in preparation for cooling.
 Seeing deteriorated when the clouds from first half cleared around
 midnight. Switchover went without incident. Winds picked up second
 half and remained near 30mph for most of the night.
