ENR CTIO Blanco 4-m 2016-04-10

Date: 
Sunday, April 10, 2016
Telescope: 
CTIO Blanco 4-m
Submitter: 
Arjun Dey
Submitter Email: 
dey@noao.edu
Observer Support: 
Manuel Hernandez
Night Assistant: 
Alberto Alvarez
Problems: 

Poor weather. We had thick cirrus all night long, with transparency=0 for several hours of the night

Comments: 

We used DECam and the dome stayed open all night long, but about half of the images we took are worthless. Hence we are counting this as 50% weather loss.

Instrument and telescope worked very well, and the technical and observing support was excellent as usual!
