APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday October 11, 2026 (SJD 61325) ---- Observing Team ---- Dan Oravetz ---- Observing Plan ---- Sun 11 Oct 2026 61325 dark (10.3 h) plus 0.2 h for 12 deg design ---- Observing Summary ---- Tonight was again lost to unusual weather, but which the forecast discussions still attribute at least partly to remnant moisture from hurricane Rachel. We had high humidity all night long, and four different waves of downpours, including some thunderstorms early in the night. Between waves of rain, and for most of the last several hours, the sky was dominated by very low and fast-moving clouds, which sometimes abruptly cleared for a minute or two to reveal stars before the next clouds covered them back up completely. ---- Engineering Issues ---- The UPS (Axxium 3000 Best Power) below the APOGEE calibration sources in the lower enclosure was beeping during my end-of-night checkout. The A/C LED was green, but there is a battery and warning LED (each is amber) lit. Since we didn't get on sky tonight I decided to hold off on the APOGEE morning calibrations in case those calibration sources would have issues given the state of the UPS. Day crew, can you please take a look at the UPS fault? There is water on the floor near that particular rack, FYI. ---- Observing Log ---- ============================================================================ AFTERNOON CHECKOUT ============================================================================ All systems alive and responsive.

Shortly after sunset, the incoming precipitation arrived. We had a downpour and thunder and lightning. 08:28Z - As of now we've had three more waves of downpours, each lasting only about 5-10 minutes, but dumping a lot of rain. 11:41Z - Called it a night. High humidity, still cloudy with some occasional fog. FPS powered-off. Positioners are home/folded. APOGEE morning cals NOT started due to an apparent fault on the UPS in the rack below the APOGEE cal box sources. ---- Mirror Numbers ---- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A: -5.4280 -5.4260 Axial B: -5.0380 -5.0390 Axial C: -5.2780 -5.2780 Trans D: -0.8740 -0.8710 Lateral E: 0.3240 0.3245 Lateral F: 0.5335 0.5335 GALILS Commanded: 11450 -1050 5900 26550 -14400 -13850 Actual: 11450 -1050 5900 26550 -14400 -13850 SETMIR VALUES PrimDesOrient: 0.0 -43.05 -8.77 -751.82 -556.2 PrimOrient: -1.06 -43.05 -8.77 -751.82 -556.2 SECONDARY: ---------- Focus: 0.0000 Air temp: 0.00 Altitude: 30.0 MIGS TONIGHT NOMINAL Axial A: -7.9550 -7.9570 Axial B: -6.1100 -6.1140 Axial C: -6.0770 -6.0790 Trans D: 0.2060 0.2050 GALILS Commanded: 359800 381150 340350 -1550 1800 Actual: 321599 349567 299609 -1550 1800 SETMIR VALUES SecDesOrient: 257.0 14.2 5.9 -72.0 -12.76 SecOrient: 256.79 14.03 5.88 -72.36 -11.95 ---- Telescope Status ---- Status at close: Telescope stowed at: 121.0, 30.0, 0.0 mount Instrument mounted: FPS Counterweights at: manually adjusted for telescope balanced w/ FPS LN2 autofill systems: Connected and turned on 180L LN2 dewar scales: SP1 162 lbs, 25 psi FPS Status ========== CP10 Loop = 7.55 L/min GFA Loop = 2.44 L/min Supply pressure = 43.2 psi Return pressure = 28.3 psi Chiller Status ============== Set temperarature = 13.5 C Flow = 5.2 Gpm ---- Software Used ---- STUI : 1.7.21 alerts : 2.3.0 boss : 6.0.5a1 -boss.specMec : 3.0.4 apo : 4.1.0 fliswarm : 0.7.0 jaeger : 1.11.2a1 kaiju : 1.4.1 coordio : 1.18.1 fps_calibrati : 2025.12.04+3e7e2d8 cherno : 1.2.2 astrometrynet : 0.97 hal : 1.4.1 hartmann : 2.0.2 hub : 5.0.1a0 mcp : 2.3.1 -mcp.plc : 35 -mcp.azFiduci : v1_154 -mcp.altFiduc : v1_154 -mcp.rotFiduc : v1_154 tcc : 1.4.0 apogee : not available apogeecal : not available apogeeql : 2.0.0a0 STUIAdditions : 3.1.18 boson : 0.7.0 sdss-obstools : 3.9.3 TPM : 1.2-31-gd7eb MCP : 2.3.1 PLC : V35 Fiducials : v1_154 idlspec2d : 6.3.0dev Kronos : 2.1.0a roboscheduler : 2.1.0 ---- APOGEE Data Summary ---- 61324 morning cals: APOGEE data list, mjd=61324, all raw_data: /data/apogee/utr_cdr/61324/apRaw-*.fits archive: /data/apogee/archive/61324/apR-[a,b,c]-*.apz quickred: /data/apogee/quickred/61324/apq-*.fits ------------------------------------------------------------------------------ mjd i UT File/Exp Imtype Nread A/B Dth Design-Cfg Arch Offset %Flux/FPI Comm ------------------------------------------------------------------------------ 61324 11 11:28 57620011 Dark 60 B 13.5 ---------- a-b-c -
