ENR CTIO Blanco 4-m 2016-06-11

Date: 
Friday, June 10, 2016
Telescope: 
CTIO Blanco 4-m
Submitter: 
Eric Mamajek
Submitter Email: 
emamajek@pas.rochester.edu
Observer Support: 
David James
Night Assistant: 
Claudio Aguilera
Also Present: 
Hernan Tirado, Markus Rabus
Problems: 

Clouded out first quarter and last quarter.
Observed through thin clouds ~11:30-3:30.
Very dense cloud bank associated with large system moved in - closed up for night.

Comments: 

Issue with ARCoIRIS calibration lamps from the previous night of engineering was fixed during the day before we started.
Pointing model generated during previous engineering night worked great - very repeatable pointing all night.
All systems were operating smoothly - ARCoIRIS, TCS, etc. Thank you Hernan, Claudio, and David for your help. 
With the thin clouds during middle of night we were only able to observe a small number of our
brightest targets (J~14 just visible with slitviewer; mostly stuck to J~11-13 targets).
I have more general comments on ARCoIRIS that I will save for the EOR.
