              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland,C.Gray
Opened the dome at 4:40 to ventilate.
Closed at 6:30 since the sky was too bright to effectively observe.
Overall it was a pretty quiet night with good seeing.
Obs-specs, just remember to keep an eye on the ion pump for arctic, its been slowly increasing/softening.
Happy holidays everyone :)
