              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley, R.McMillan
Dewar 5 has a leak on the liquid valve.  See PR.
Worked on DIS collimator (Russet)
Reset axis controllers
Dis throughput cals via Jack's script
Dis slitviewer vs spectro focus (some clouds)
Feige 34  (clear)
Feige 67
Feige 66
Shack-Hartmann, corrected collimation
Did an altitude sweep with SH
Zeroed rotator
NA2 pointing model, implemented
NA1 pointing model, not implemented
Problems:
06:01:58 UT  While doing the altitude sweep, found a high frequency shiver mostly in altitude.
09:42:56 UT  Had a "motion error too large" in altitude during the NA1 pointing model.  The usual stop button press/release cleared it.
