ENR CTIO Blanco 4-m 2013-08-17

Date: 
Saturday, August 17, 2013
Telescope: 
CTIO Blanco 4-m
Submitter: 
Kathy Vivas
Submitter Email:

Observer Support: 
Alberto Alvarez
Night Assistant: 
Leonardo Paredes
Also Present: 
Mauricio Rojas
Problems: 

Problems started exactly at midnight. There was an interlock alarm about a problem with OCS. SISPI was resarted several times. The system initialized well but when an image was taken (either a bias or an object) the failure appeared again. The crates were restarted but it did not change the situation. Same failure
appeared again. Mauricio Rojas talked extensively with Marco Bonati on the phone but they were not able to identify the problem.

Unfortunately there is no internet in the mountain and thus it was not posiible to contact via skype or e-mail the experts on the system.

At 4am I decided to close for the night.

Hopefully this can be solved during daytime. Thanks!

Comments: 

We took data from  7:15pm to midnight. The system worked perfectly well during that period of time. We had clear skies and good seeing.
