              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Clouds, clouds, cloud.  Humidity.  Terrible seeing for most of the night.  But we observed!  I delayed opening at the beginning of the night due to nearby rain. UW01 struggled the entire shift for every photon.  However, things started clearing up around 1 am, which is when the humidity spiked but was never bad enough to close.  NM03 could not use their first hour of observations and donated it to the AD01 program. Once they were on, the seeing went subarcsecond!
No problems tonight
