              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started with distant storm clouds. The humidity was present but not high enough to cause problems and we were able to open on time.  Then, Will Robinson hour started: DANGER!!  The humidity went up very quickly and I stayed open as long as humidly possible but we had to close at 21:55.  We were not able to open the rest of the night due to humidity.
The mini mac for Dataq froze and had to be rebooted. NICFPS warmed again and may have been due to an improper fill.  It was filled again at 03:30am and has remained cold.
