              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out mostly cloudy with signs of virga, which delayed us opening by 15 min. Things cleared up several times during the night and we had good seeing.
Everything was good with NICFPS when we were on sky but after I dismounted and our user took their darks, the images were bad. There were three vertical bands of high counts. A NICFPS expose init and that solved the problem. Maybe something was jostled during dismount?
