Telescope: 
CTIO Blanco 4-m
Submitter:

Observer Support: 
Alberto Alvarez
Night Assistant: 
Zenteno
Problems: 

There was a login issue at the beginning of the night, where there was no 2014A-0386 directory and new images couldn't be sent there. Restarting SISPI seemed to resolve the issue. As it turns out, all tonight's calibration files were run under the previous observer's login. Perhaps the exact procedure for creating new logins could be made more explicit?

Also, the Exposure Table GUI kept throwing "Page(s) Unresponsive" errors.

Otherwise, there weren't any errors that weren't seeing related!

Comments: 

Seeing was pretty bad; never below 1.2", usually at 1.5" and sometimes as high as 2.5". Of course, we lost guiding when the seeing got this bad, but it only happened 4th quarter.
