ENR CTIO Blanco 4-m 2018-11-09

Date: 
Friday, November 9, 2018
Telescope: 
CTIO Blanco 4-m
Submitter: 
Arjun Dey
Submitter Email: 
dey@noao.edu
Observer Support: 
Hernan Tirado
Night Assistant: 
Claudio Aguilera
Also Present: 
Tim Abbot (remote startup support); Shadab Alam (observer)
Problems: 

- At start of the night (00:00ut) we had an interlock issue, solved by Hernan Tirado by reset on SISPI

- Seeing was mediocre through the night (and not just at airmass > 2). Help would be appreciated.

 

Comments: 

Support was excellent, as always!

Night started with some scattered cirrus, but appeared to be clear for 2nd quarter, and then cirrus began to come in again during the 3rd quarter. Seeing started at mediocre and got progressively worse through the night.

The espresso machine's button labels have worn off. We guessed, made coffee, and the machine did not explode. However, it would be great if a label maker could be employed to help future infrequent (and coffee-deprived) visitors.
