ENR CTIO Blanco 4-m 2013-06-18

Date: 
Tuesday, June 18, 2013
Telescope: 
CTIO Blanco 4-m
Submitter: 
Christopher Klein
Submitter Email: 
cklein@berkeley.edu
Observer Support: 
David James
Night Assistant: 
Mauricio Rojas
Also Present: 
Claudio Aguilera
Problems: 

Overheads longer than they should have been for many of our observations. The telescope waited until the previous image reached the digitized stage before slewing the telescope for the next observation (instead of slewing directly after the end of the exposure). This caused an extra ~24 seconds of overhead for these observations. This aberrent behavior halted around 2/3 through the night, we don't know why.
