              ------------- ACTIVITY LOG --------------
Observing Specialist:    J.Dembicky
Some pesky clouds during the first program, mostly clear the remainder of the night.
 NA2 guider quit a couple times during the first half of the night (SPIcam), it needed to be
restarted from TUI.  We didn't have any problems with the NA2 guider during the second half
(DIS).
At the end of the night when I went to park the telescope, DIS did not want to rotate to 0 deg.  I
had to stop the drives and re-start them, which fixed the problem.  RotDTime error.
I parked the telescope at 15 deg to change out one of the truss lamps.
