ENR CTIO Blanco 4-m 2026-01-29

Date: 
Thursday, January 29, 2026
Telescope: 
CTIO Blanco 4-m
Submitter: 
Guillermo Damke (1st half) / Ko Ishida (2nd half)
Submitter Email: 
guillermo.damke@noirlab.edu
Observer Support: 
Manuel Hernandez
Night Assistant: 
Claudio Aguilera
Also Present: 
Rodrigo Hinojosa, Sean Points
Problems: 

We lost the connection to the 2MASS source catalog in DS9 during the pointing procedure. The actual pointing precision could no be checked as a result. We should have the option to connect to other servers (mirrors) from the NEWFIRM machine, in case that this problem happens again.

The AEON "acquisition done" button is not re-populating some of the exposure parameters in the NEWFIRM GUI, after the user modifies them to check the focus. I sent more details of the problem to Hannah Crayton, so that she can check if there are any problems.
