ENR CTIO Blanco 4-m 2026-01-19

Date: 
Monday, January 19, 2026
Telescope: 
CTIO Blanco 4-m
Submitter: 
Tim Abbott
Submitter Email:

Observer Support: 
Manuel Hernandez
Night Assistant: 
Claudio Aguilera
Also Present: 
Alfredo Zenteno, Tim Abbott
Problems: 

Keeper proxy 4 froze twice.  Claudio got it back once while we observed via Zoom (less than optimal), however this also created an oddity in which the image data was not visible on observer4, although it was still showing up on observer2.  Restarting SISPI fixed that.  On the second occasion proxy 4 failed we continued with Zoom rather than lose more time.
