                ------------- ACTIVITY LOG --------------
 Observing Specialist: J. Dembicky
 I started cooling the enclosure around 19:15 and opened around 20:10
 under partly cloudy skies.
 A dust event occured around 22:30 which closed us down and then the
 humidity went thru the roof.  High humidity conditions prevailed for the
 remainder of the night.
