              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
During my checkout yesterday the echelle slit camera failed. A hub restart, init, and removing the ecam directory for that UT date fixed it.  THe same thing happened again today while doing checkout.  Same fix.  Not sure if this is becoming a recurrent problem or not.
Humidity was borderline at sunset but we opened.  Clouds started forming/coming in around 22:30.  We closed at 23:00 due to clouds and humidity.
We opened briefly around 01:40 but closed only a couple minutes later when the humidity rose above the closure limit again.  We never re-opened for the remainder of the night due to high humidity.
