              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We weren't so lucky tonight. Thunderstorms started at sunset and we were never able to open. We had rain and the beginning of the night and then high dust at the end. The UW09 did their second night of pre-observing training and will ready for sky tomorrow! ...just in time for the clouds. It was so thick we never had any hope of observing tonight.
For engineering I tested the tertiary and all moved well! Dis red showed horizontal lines during checkout so I restarted the power supply and all was good.
Jack worked on updating the nightlog at it is good as well!
