ENR CTIO Blanco 4-m 2016-09-11

Date: 
Sunday, September 11, 2016
Telescope: 
CTIO Blanco 4-m
Submitter: 
Kyle Story
Submitter Email: 
kstory@stanford.edu
Observer Support: 
Carlos Corco
Night Assistant: 
Alberto Alvarez
Problems: 

# Before observations began, the dome encoder readout stopped working.  TelObs fixed this by re-booting the encoder readout computer.  This is now working fine.
# The afternoon dome flats were taken, however the images from the flats are not in the expected foulder on observer2.  We have not been able to run "flatcheck."
# RASICAM was not responding at the beginning of the night.  TelObs went out and re-booted it.  It is now working.

Comments: 

# At the beginning of the night, the total seeing was terrible.  The DIMM seeing was as high as 3.8.  Seeing is improving, but is still not very good.

# The primary mirror was hotter than the low dome for most of the observing night.  This contributed to the bad seeing for the night.
