Subject: 2.5m obslog 20250912 (SJD 60931) From: asimmons@apo.nmsu.edu Date: Sat, 13 Sep 2025 10:56:22 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday September 12, 2025 (SJD 60931) ---- Observing Team ---- Audrey Oravetz Conor Sayres (online) Kaike Pan (online) John Donor (online) ---- Observing Plan ---- Pointing model Guide on fields Focus BOSS cameras/collimator ---- Observing Summary ---- Lots of clouds, rain, and humidity tonight. We never opened but many in-dome tasks were completed. The BOSS cameras were focused with the collimator actuators just above the center of their ranges for a temperature at around 9C. Both rings were verified to likely have enough play in them to handle temperature swings throughout the year. XMID and WAVEMID values were adjusted and now they should be in spec. BOSS monthly biases, darks, and flats were taken. Conor pushed some new FPS calibrations to the robots and tested their motion. Images look great. Robot 1324 looks a bit off from where it is commanded to go. No collisions were witnessed. We now have permission to move the robots during the night. Kaike and JohnD checked in online for a bit. ---- Observing Log ---- Afternoon: ========== The weather does not look promising tonight. Lots of clouds around.
