ENR CTIO Blanco 4-m 2013-04-19

Date: 
Friday, April 19, 2013
Telescope: 
CTIO Blanco 4-m
Submitter: 
Andrea Kunder
Submitter Email: 
akunder@ctio.noao.edu
Observer Support: 
Hernan Tirado
Night Assistant: 
Claudio Aguilera
Also Present: 
Klaus and Nick were present remotely.
Problems: 

The guider gui was not working all night.  Claudio said that guider offsets were being received by the TCS and I could see in the telemetry Guider window that guide stars were being found.  It would be nice for the guider gui to work, though.  Restarting it did not help.  The guider could not find guide stars twice (in crowded fields).

 

The observer console gui timed out twice while I was taking flats.  I restarted all the GUIs with the buttons in the scroll bar on observer1, and the GUIs did not come back in the same place they normally are.  Of course I rearranged them manually.  During the night, the observer console GUI timed out two more times.

 

Comments: 

 

The wind speed was high all night.  I asked Claudio to raise the wind screen--that did not seem to help with the seeing.  Seeing varied from 0.9" to 2.8" (ellicipties were consistently small < 0.075", which gave me some confidence that the telescope was in focus).  Claudio made sure that visually the wind screen was not eclipsing the field of view of the telescope.
