              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Closed at 21:37 because of radar returns directly overhead. Had to wait
until 00:20 before it was safe.
DD04 user accidentally switched TripleSpec slit from 1.1 to 1.7. I
reminded him that only 1.1 was available, but the instrument control panel
and the guider were already confused. I had to power-cycle the leach
controller and restart the nubs. The process took about 15 minutes.
Other than that, night was clearish and uneventful with seeing from 1.25"
to 2.5".
