              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started clear with good seeing. NM02 opened a little after sunset in order to finish up their epic cals. I did a quick and dirty fixed to the NAIC instrument block in order to improve pointing (it did!). Clouds starting rolling in around midnight and it got pretty cloudy, but we were able to punch through. We saw more comets! Sadly, not more moon. Maybe next time.
No problems tonight.
