                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 We were closed all night for a variety of weather including snow,
 clouds, and high winds, but especially high humidity because the
 primary mirror was still cool from the previous night.  I did a
 little cloudy-night working testing new slit wheels for DIS.
