ENR CTIO Blanco 4-m 2014-04-07

Date: 
Monday, April 7, 2014
Telescope: 
CTIO Blanco 4-m
Submitter:

Observer Support: 
Alfredo Zenteno
Night Assistant: 
Juan Espinosa
Problems: 

The dome failed to work at the beginning of the night.  I think the error was that the encoders could not be read; anyway the result was that we could not rotate the dome.  This was resolved after a little over an hour.  

A minor, unrelated issue: it appears that Image 300398 was not delivered, though it was built and saved locally.

Comments: 

Although this form will not allow me to submit a seeing value larger than 3 arcsec, the seeing was in fact worse than this for much of the night, ranging from 3.5 to 4.5 arcsec.  It was considerably better, about 1.5-2 arcsec, in the last hour of the night.
