Wednesday, February 9, 2022

Observer Support: 
Jacqueline Seron
Night Assistant: 
Alberto Alvarez
Also Present: 
Alfredo Zenteno, Erik Wasleske, Xiaojing Lin, Alistair Walker
Problems: 

Issue directly after handoff. Alfredo and Alistair investigate what is believe to be a Guilder Fiber issue, resulting in a max exposure time of 100sec and a need of "exclude" : "guider", command in the .json files. This issue lost us roughly 1 hour of exposure to diagnostic runs and forced us to adjust our scripts for the rest of the night to a stacking method of shorter exposures. Alistair reached out to the engineer with plans to address this come morning.
