               ------------- ACTIVITY LOG --------------
 Observing Specialist: Jack Dembicky
 I started the cooling fans around 16:30 but kept the dome closed so that
 DIS cal lamps could be taken. I opened the enclosure and louvers around
 18:10 under partly cloudy skies.  Clouds stopped observations around
 18:40 but thinned out around 20:25 for us to get some useful data.  The
 clouds came back around 23:00 and basically closed us for the remainder
 of the night.
