              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Decent seeing, some thin clouds here and there but mostly good observing weather!
NM02 took cals until 18:40.
At checkout, gcam needed a nubs restart and the ARCTIC ion pump controller on high voltage (since yesterday evening, confirmed with Mark) but the temperature held at 182K all night.
At 19:00, the 2.5 Air TSL cycled to unreal values affecting ARCSAT.
Towards the end of the night KOSMOS exposures started failing with "Torrent Error: ERROR: command > 1u per 0.1 cubic feet.
