              ------------- ACTIVITY LOG --------------
Observing Specialist: M.Croom
A.Townsend support ObsSpec.
Did not open. Snow/ice on enclosure persisted and the limited operating conditions (esp glass temperatures below freezing) were not met all night. Otherwise, clear conditions all night.
Echelle quartz lamp was sporadic. It worked for the starting IOL and for cals supporting NM06 tonight (UT20241120) but not for ending IOL. PI A.Peck is willing to share NM06 flats taken tonight with other observers if needed.
Parked telescope at 45,75 with heaters on.
