Observing Specialist: T.Sutherland
Thanks Candace for the remote support!
It would have been the perfect observing night, but alas, there was snow on the 3.5m dome so we had to stay closed.
Had to correct the pointing/clock time on arcsat.
Roof heaters stayed on all night.
Kosmos LN2 hose not connecting well to Kosmos. It seems to be striped.
