              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Relaxed the primary during checkout per Bill's instructions. Saw normal
noise on PMSS.
Dust and high winds closed us at 20:02. Opened again at 20:23. Finished at
21:47. Checked collimation and pointing with Echelle before switching to
NICFPS.
During CU02- User Francisco Mueller had connection issues from CU. He was
not able to get ob sky until 01:34.
During CU01, at ~05:25, saw a lot of noise in the pmss system, and the
telescope would not obey small offsets in altitude. I stopped and
restarted the axes. This seemed to clear the error.
The rest of the night went okay, even though the seeing was horrible for
the majority of the night.
