              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We had a clearing around 01:30.  When I went to prep the telescope to open (set instrument) I encounted an error with the Secondary mirror.  Similiar to the other night, this time when switching to the echelle.  I called Russet to re-home things.  Russet recommeded slewing the telescope first before doing a set inst to help the actuators, in case of failure.
We had clouds re-forming to our west and move over us by 02:00.
We finally opened around 03:00.
