ENR CTIO Blanco 4-m 2015-07-21

Date: 
Tuesday, July 21, 2015
Telescope: 
CTIO Blanco 4-m
Submitter: 
Eduard Rusu
Submitter Email: 
cerusu@ucdavis.edu
Observer Support: 
Leonardo Paredes
Night Assistant: 
Alberto Alvarez
Problems: 

Lost guiding at 06:50 UT due to clouds - lost frame 872 and put queue on hold.  We were a bit fooled by the weather, since the Rasicam display froze.

Shutting the dome at 07:25 UT due to the weather conditions.  Called it a night at 08:05 UT.

 

Comments: 

Most of the seeing measurements were taken in  u-band.

Amount of sky covered by clouds was highly variable for the first part of the night as a system came in from the Pacific.  Conditions continued to deteriorate during the third quarter of the night, until we had to close the dome at 07:25 UT.
