ENR CTIO Blanco 4-m 2015-03-29

Date: 
Sunday, March 29, 2015
Telescope: 
CTIO Blanco 4-m
Submitter: 
Anna Patej
Submitter Email: 
apatej@physics.harvard.edu
Observer Support: 
Manuel Hernandez
Night Assistant: 
Alberto Alvarez
Also Present: 
David Schlegel, Greg Rudnick
Problems: 

There was another telescope driver failure tonight.  This caused a loss of about 1.75 hours of observation.  The operators determined that we could avoid the problem by limiting ourselves to targets with dec <+13 deg.  We were able to comply with this constraint.  Observations in our program's run in a week's time will need to be conducted at dec >+13 deg and so this problem will need to be fixed by then.
