                               ACTIVITY LOG
The telescope was opened at 18:00. Early in the afternoon, Bob Lowenstein
updated the GRIM software to GRIM2.com.  Karen Gloria tested the new
controller software by running a long exposure sequence, with no hang ups.
At 19:00, Karen and I did a short amount of GUIDER test exposures, because
the GUIDER MAC was moved to the observing level.  They seemed to work well.
Karen then began slewing the telescope to test the TCC to see if the slews
ran properly and there were no problems with communications to the axis
controllers.
We had to close at 19:50 due to overcast skies that persisted through the
night.
The DIS LN2 Status was fine all evening.
I had to fill SPICAM at 19:30, 00:05 and 05:30.
