Telescope and Instruments Report
The detailed site report is included below, followed by additional information discussed during today's meeting.
3.5-m Telescope and Instruments Highlights, 12/05/2023 – 2/06/2024
1) Overview
December and January have been wintery at APO. Telescope has continued to work well. Weather has been challenging for observing. A consistent number of snow storms causing lost time for high humidity and snow on the enclosure roof have impacted multiple programs.
Planning is under way for an upcoming visiting instrument team in mid February, and a large class in early March.
2) Operations
3.5m Telescope:
3.5m Telescope: Telescope is working well, motion errors seem to be of the seasonal type.
0.5m Telescope: Nothing to report
KOSMOS new slits (high/center/low for both 1.25 and 20 arc-second widths) have arrived and after an initial issue with non captive screws, are ready to use. Vacuum is softening slightly in KOSMOS and it will need a warm up/pump/cool down cycle as soon as the schedule allows it.
ARCTIC diffuser’s rotator service is being planned for later in the spring.
Agile Instrument TEC controls failed. Attempted repairs have been unsuccessful so far.
ARCES had a failure in the fill system which has caused the instrument to start to warm up. Fill system is being repaired and the echelle will be fully warmed, vacuum pumped and cooled as quickly as it can be.
DIS red camera has experienced a failure that is causing all frames to be all the same DN value. Failure is being investigated.
