              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
ecam needed to be rebooted through obs1 at the beginning of the night.
The evening started with complete cloud coverage.  There was a possibility of rain at the beginning of the night but we were able to open right on time. We fought with the clouds for all of A half and some of B half.  However, everything cleared up nicely around 2am.
No problems tonight.
