              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Did anyone expect us to open tonight?  No?  Great, then hopefully no one was overly disappointed :( The night started out with rain, hail, snow, wind, fog, frogs. JK, no raining frogs...yet.  Total snow accumulation between 2-4 inches.
CU05 was supposed to be on site tonight to begin their training but the trip was cancelled due to the extreme weather and unsafe driving conditions.  However, we were able to conduct a Skype training! They didn't get on sky but they slewed around and took lots of cals and had a lot of fun!
There were several light power flickers but nothing to bother the DIS blue pump until 05:30am. Emergency valve is closed as is the pump valve. Winds are reaching 50 mp but power is still good. Fingers crossed things aren't too bad during the afternoon winds...
