It continued to drizzle for quite awhile afterwards. 05:13Z - A nice sucker-hole appeared, but there was not enough time to open and get set up before the threat of rain came back. 05:45Z - Lots of clouds returned, as well as some radar. Absorbent pads were placed in the enclosure. There is no hope for observing tonight. Started APOGEE morningcals and turned off the FPS. ---- Mirror Numbers ---- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A: -5.4290 -5.4280 Axial B: -5.0490 -5.0490 Axial C: -5.2780 -5.2770 Trans D: -0.8720 -0.8730 Lateral E: 0.3240 0.3240 Lateral F: 0.5330 0.5330 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: -7.9570 -7.9570 Axial B: -6.1080 -6.1070 Axial C: -6.0780 -6.0780 Trans D: 0.1940 0.2040 GALILS Commanded: 354300 371850 335050 -1500 1850 Actual: 321731 349876 299533 -1500 1850 SETMIR VALUES SecDesOrient: 257.0 14.2 5.9 -72.0 -12.76 SecOrient: 256.9 14.16 5.92 -72.34 -13.16 ---- Telescope Status ---- Telescope stowed at: 121.0, 30.0, 0.0 mount Instrument mounted: FPS Counterweights at: manually adjusted for telescope balance w/ FPS mounted LN2 autofill systems: Connected and turned on 180L LN2 dewar scales: SP1 175 lbs, 20 psi FPS Status ========== CP10 Loop = 7.60 L/min GFA Loop = 2.30 L/min Supply pressure = 42.8 psi Return pressure = 28.6 psi Chiller Status ============== Set temperarature = 17.0 C Flow = 5.0 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 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 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 ---- 61286 morning cals: APOGEE data list, mjd=61286, all raw_data: /data/apogee/utr_cdr/61286/apRaw-*.fits archive: /data/apogee/archive/61286/apR-[a,b,c]-*.apz quickred: /data/apogee/quickred/61286/apq-*.fits ------------------------------------------------------------------------------ mjd i UT File/Exp Imtype Nread A/B Dth Design-Cfg Arch Offset %Flux/FPI Comm ------------------------------------------------------------------------------ 61286 53 12:10 57240053 Dark 60 B 13.5 ---------- a-b-c -
