              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out *not* super humid!!  There were some gray rain clouds but they were small and cleared out by sunset to be replaced by white clouds.  Seeing was moderate all night. We closed at 20:54 due to threat of rain.  We reopened at 21:43 and remained open until the end of CU03s time even though the humidity was high.  This made me very nervous but I wanted Bally to get his time.  I closed at switch over at 01:04 and remained closed until 02:00.  We fought the humidity as long as we could but the clouds hunkered over the star CU04 was interested in.  At 03:55 I called it due humidity and the fact that we just couldn't punch through the clouds.
No problems tonight.
