ENR CTIO Blanco 4-m 2013-06-19

Date: 
Wednesday, June 19, 2013
Telescope: 
CTIO Blanco 4-m
Submitter: 
Christopher Klein
Submitter Email: 
cklein@berkeley.edu
Observer Support: 
David James
Night Assistant: 
Claudio Aguilera
Problems: 

Continued to experience the bug in the exposure queue where the telescope waits until the previous exposure is digitized before slewing for the next exposure. (Normally it should start slewing as soon as the shutter closes on the previous exposure.) At the suggestion of David James (who was in communication with the software author) we allowed the exposure queue to empty out before loading up the next script. This seems to work most of the time and prevents the unnecessary overhead.

Comments: 

The DIMM seeing monitor says the seeing varied between 0.5 and 0.7 arcsec, but the actual seeing through DECam was around 1.5 arcsec (also corroborated with 1.3-m observer). We think that the seeing and flux plots are incorrectly labeled in the DIMM monitor webpage.
