ENR CTIO Blanco 4-m 2016-04-16

Date: 
Saturday, April 16, 2016
Telescope: 
CTIO Blanco 4-m
Submitter: 
Sean Johnson
Submitter Email: 
seanjohnson@uchicago.edu
Observer Support: 
Sean Points
Night Assistant: 
Claudio Aguilera
Problems: 

The data acquisition software crashed five times, four of which were after 900s science exposures. Including the lost exposures and time taken to restart nocs, total time lost was 1.25 hrs.

The afternoon biases on COSMOS showed unusual variation. I am taking a long series of biases this morning to help diagnose.

Seeing was good (regularly 1" measured in COSMOS at airmass 1.4) and skies clear most of the night.
