              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had some motion errors during check out and during one of the first slews of the night.  I'm guessing there was a collision yesterday morning due to wind and that was messing with the drives tonight.
Things were clear at the beginning of the night but poor seeing which improved...for a time.  Then the clouds rolled in and seeing became very bad but...it's spectroscopy, right?
