ENR CTIO Blanco 4-m 2014-09-28

Date: 
Sunday, September 28, 2014
Telescope: 
CTIO Blanco 4-m
Submitter: 
Chris Curtin
Submitter Email:

Observer Support: 
None
Night Assistant: 
Alberto Alvarez
Also Present: 
Leonardo Paredes
Problems: 

Had to close dome for ~40 min at ~2:30 AM due to heavy clouds, potential rain showers

Comments: 

Difficulty finding guide stars in the second half of the night.  It would be nice to be able to restart an exposure (neglecting dithering) and look for guide stars a second time for an exposure, or just look again during exposure.

I had hoped to comment on certain exposures, leaving notes for follow up or to be included with the data, but there seems to be no easy way to add a comment to an exposure in the electronic log book.
