              ------------- ACTIVITY LOG --------------
Observing Specialist:    J.Dembicky
New cold weather limits imposed today. Wind limit of 20MPH also for tonight due to ice on
lightning arrestors on building.
Temps hovered between -17C to -18C 1st half and the winds picked up to nearly 40MPH after sunset.
Temps rose slightly but winds stayed above 20MPH closure the entire night.  We gave up at 05:00.
Echelle temp -107C @05:25
Vac pump moved over to DIS (DIS is inverted to get to blue camera). 2 Heaters turned on.
I noticed there was frost on the DIS blue camera @ 05:15  (well the part from the camera to the
vacuum connection).  This was not present on the red camera.
