              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
There were some clouds at the beginning of the night but we were able to open on time.  The clouds formed over us for several hours before clearing.  We had clear skies and good seeing for the rest of the night.
No surprise, Tspec was bad. I powered it off during afternoon fills and left it off.  I left the Tspec aux tank plug out as instructed and the temp of the AUX tank quickly decreased to 80.5K and stayed there the rest of the night.
