              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Well, while we were opened we had good seeing.  I thought we were suppose to be clouded out tonight but we started the night clear.  However, two system converged on us, one from the west another from the east. Clouds started popping up very quickly and there were radar hits so I decided to close at 22:07.  While it never rained, it did stay cloudy for several hours.  We were able to reopen at 01:42 under completely clear skies. Poor Kristie, maybe Melissa wasn't the cursed observer after all...
No problems tonight.
