- Things to keep in mind:
- Watch for opportunity to do ptc scan. "Opportunity"= dome closed at night.
- defocus_nightly.json is suppose to be run weekly- when are we running next?
- According to Aaron, photometric conditions aren't important, but seeing should be below 1.2-1.3"

Notes from the 4PM Meeting¶
- SISPI is having problems at the end of the night. Likely GUI only, likely related to number of items in queue.
Do standard star observations one star at a time.
- We are discussing the atmCam operations with Ting and Hernan
- Klaus requests a handful of diagnostics iff the SISPI guy slows way down tonight:
- try refreshing the ics guy
- try starting a SISPI guy on a laptop- no control possible but of interest is whether it is also slow
- look at network traffic on observer1
- in general keep an eye out for details of interest.
Other Notes¶
- Are there data to declare bad?
Yes, the apply_data_gui shows many (100?) main survey observations to
declare bad- these are from nights earlier in the run. It seems
processing is catching up.
- When were the SN last observered?
