              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Before getting on sky, NICFPS gave us some trouble. During Cu04's cals, I
had to do a nicfps expose init. That resolved the problem to finish darks
and biases. Before getting on sky, I opened the dome and took some test
exposures with NICFPS, but they failed or hung up. I restarted the nubs,
the ICS, and the leech controller. Each time I re-initialized the
instrument, I exposed with NFS=0. Upon chaging them to NFS=8, the exposure
would fail.
After going through this a few times, I called Bill for help. He was able
to get it going again. Several of the error were because I did not have
long enough exposure times for NFS=8. I will familiarize myself with this
in the future. The pressure went to 8.9e-6 torr at 21:10. At this, even
with the current load was maxed out, we decided to let it be and monitor
the temperature.
The rest of the night was productive, with good, nearly-constant seeing.
