              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
NM01 users were taking cals this afternoon.  We opened just after sunset when they had finished.
A nice clear night all night, seeing wasn't the greatest thought.  We started with around 1 arc sec seeing but soon after seeing degraded to about 2.5 arc sec.  It slowly got better during the night and back to around 1.4 by the end of the night.
My observers target was setting, so they wouldn't have enough time for another data cube, so we closed a little early.
