ENR CTIO Blanco 4-m 2025-07-29

Date: 
Tuesday, July 29, 2025
Telescope: 
CTIO Blanco 4-m
Submitter: 
Farzaneh Zohrabi
Submitter Email: 
fzohra2@lsu.edu
Observer Support: 
Hernan Tirado
Night Assistant: 
Alberto Alvarez
Problems: 

Due to bad weather, we had to close the dome twice in the beginning of the night and skip twillight observations. 
Observation was interrupted by two system errors during night, however we resumed observing after few minutes.
Due to overcast we had to close the dome at 4:16 CLT.

Observing was switched to the Zoom control laptop after Keeper failure. The ToO json scripts were not on the machine, and an attempt to do a git transfer failed (possilby due to expired credentials?). In the future, could the jsons be added to the Zoom laptop as well, in case Keeper fails? Alternatively, if there is a way to update the git credentials on the Zoom laptop for the ToO program, that would work too.
