              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Engineering was co-opted at the start of the night by NA01.  Was able to reset axes and zero rotator during checkout. We let NA01 AP01 and NM04 have time on the scope, then did a collimation check (no change), pointing model (not yet implemented) and an instrument block for another one of arctic's quads.
Skies were clear with good to excellent seeing. Some clouds started coming in around 05:00. Dome was open until twilight.
