Support Astronomer : D. Thompson
Instrumentation        :


Summary: At sunset: clear sky, humidity 40%.  SW wind 9 m/s

There is still a problem with the secondary, so we are forced to use to LBC.
If the seeing is significantly worse than required by the projects, we will take "free" data.

we are monitoring the seeing. In case it is stable and under 0.8 for the next exposure we’ll move to the OSU_QSO program

seeing red~0.8 blue~1.0
seeing red~0.9 blue~1.1
psf slightly elongated in the blue but not enough to refocus 
seeing red~1.0 blue~1.6 (repeated)
loosing focus on the blue arm
06:40: aborted exposures, refocusing
created new OB to finish remaining exposures  
06:53:
start again
still slightly elongated in the blue but much better than previous exposures

either out of focus or really bad seeing 
09:12
try to refocus (seeing went up, but it is going down again)
copoint done (Scarlata doesn’t have copoint script)


09:16

move to Claudia Scarlata’s field
No focusing script, making focusing field
hopefully seeing will go down again
