ENR CTIO Blanco 4-m 2018-07-11

Date: 
Tuesday, July 10, 2018
Telescope: 
CTIO Blanco 4-m
Submitter: 
Clara Martinez-Vazquez
Submitter Email: 
cmartinez@ctio.noao.edu
Observer Support: 
Manuel Hernandez
Night Assistant: 
Claudio Aguilera
Also Present: 
Alistair Walker
Problems: 

1) Several faliures while restarting SISPI  (interlock, DHSA, pipeline3). Marcos, Klaus and Heinrich helped with this and we could be on sky around 09:00 PM local time.

2) The telescope mirror support air system failed at 11:20 PM local time. The image 754229 is not good (you can see triangles instead of donuts). Javier came at the telescope and fixed it with the help of Claudio. We went back to sky again at 01:10 AM local time.

Comments: 

Image quality seems to be good. Ellipticity around 0.05.
