              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland

Clouds and nearby radar kept us closed at the beginning of the night. Things cleared and were able to open before 23:00. Clouds rolled in again around 2:30-3am and stayed put. But we got data nonetheless! 

No morning echelle iol, cals were being taken.
