APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday January 07, 2026 (SJD 61048) ---- Observing Team ---- Dmitry Bizyaev ---- Observing Plan ---- Wed 07 Jan 2026 61048 0.73 01:10 01:25 12:53 01:32 13:03 --- dark until 05:05 ( 3.7 h), then bright ( 8.1 h, w/ 0.3 h for 12 deg design) ---- Observing Summary ---- The entire nightwas lost to showers, clouds, high humidity and high winds. ---- Observing Log ---- Afternoon ========= All software and hardware checked, no problems found. During the afternoon checjout early "fliswarm reconnect" complained to GFA3, and the GFA camera computers were rebooted. It fixed the problem. The BOSS collimation looks OK, not adjusted. 23:51:51 Hartmann collimate output sp1: offset: r= -659 (In Focus); b= -1.2 (In Focus) sp1: pred. move: spAverageMove= -137 sp1: pred. resid: r= -522, b= -1.6, txt= OK, spTemp = 4.2 cwPositions = 35 35 35 35; MCP instr = 10 (mounted); ---------- motorPosition sp1: -3341, -3324, -3307; ---------- Median spectrographs temperatures: Tsp1= 4.1 Outside air temperature= 0.0; ---------- Boss CCD Temp : sp1r0= -126.6 (-126.6); sp1b2= -101.6 (-100.0); sp1LN2: 10.0; ---------- Apogee: vacuum = 4.626e-07 ( < 1.1e-06 ) ln2Level = 93.652 ( > 85 ) ---------- Weather: Humidity = 78.8 % AirTemp = 1.8 C, DpTemp = -1.5 C diff= 3.3 C wind25m = 24.2 mph, direction = 211.0 deg ---------- semOwner = TCC:0:0 stuiVer=(1.7.19 2023-01-12), pid = 800 memory = 456 MB ---------- Jaeger disabled robots: 647, 973, 986 There are 3 disabled robots Cloudy sky, high humidity, high wind gusts and surrounding radars prevented us from starting ventilayion. ===== Night ===== Cannot open because of high humiduty and radars around. 11:46Z the weather is stil inclement.
