APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday October 12, 2025 (SJD 60961) ---- Observing Team ---- Dan Oravetz ---- Observing Plan ---- Sun 12 Oct 2025 60961 dark until 05:16 (3.6 h), then bright (7.1 h, w/ 0.4 h for 12 deg design) Pointing model, weather permitting ---- Observing Summary ---- Lots of fog to begin the night. Around 07:00Z, the sky remarkably cleared, but the humidity persisted and outside surfaces remained dripping-wet. Beginning ~08:00Z there were pockets of fog actively moving through again (not just "stable" high humidity), so despite getting to see stars tonight, we still remained closed. ---- Engineering Issues ---- The 1/4" orange vinyl tubing that supplies the PMSS Pressure gauge in the lower enclosure has a leak. Pictures and email sent to John and Katie. ---- Observing Log ---- ============================================================================ AFTERNOON CHECKOUT ============================================================================ All systems alive and responsive.

Note that the 2.5m-reported humidity, while having been seemingly stable and reasonable earlier tonight, is all over the place now (again), and won't be trusted. 08:48Z - Went outside to measure humidity down at the enclosure again and then I saw more fog just below on the escarpment. Bottom line: clear (mostly; sometimes a cloud or two shows up) sky, but too humid to open. 11:06Z - Called it a night. FPS powered-off. Positioners are home/folded. APOGEE morning cals started. ---- Mirror Numbers ---- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A: 0.1030 0.1040 Axial B: 0.0019 0.0019 Axial C: -0.1750 -0.1740 Trans D: -0.0290 -0.0280 Lateral E: 0.3400 0.3400 Lateral F: 0.5460 0.5460 GALILS Commanded: 8450 -1050 8800 22100 -2000 -1700 Actual: 8450 -1050 8800 22100 -2000 -1700 SETMIR VALUES PrimDesOrient: 1.06 2.03 16.67 -410.97 -787.67 PrimOrient: 1.06 2.03 16.67 -410.97 -787.67 SECONDARY: ---------- Focus: 0.0000 Air temp: 0.00 Altitude: 30.0 MIGS TONIGHT NOMINAL Axial A: -7.6430 -7.6450 Axial B: -7.5400 -7.5410 Axial C: -7.5310 -7.5320 Trans D: 0.1810 0.1800 GALILS Commanded: 2249400 2249050 2244800 -1750 -1700 Actual: 2215710 2225594 2199313 -1750 -1700 SETMIR VALUES SecDesOrient: 1757.0 7.9 1.5 -39.3 35.42 SecOrient: 1756.97 7.94 1.49 -39.31 35.16 ---- Telescope Status ---- Status at close: Telescope stowed at: 121.0, 30.0, 0.0 mount Instrument mounted: FPS Counterweights at: manually adjusted for FPS mounted LN2 autofill systems: Connected and turned on 180L LN2 dewar scales: SP1 115 lbs, 22 psi FPS Status ========== CP10 Loop = 7.58 L/min GFA Loop = 2.32 L/min Supply pressure = 44.4 psi Return pressure = 29.7 psi Chiller Status ============== Set temperarature = 12.0 C Flow = 5.0 Gpm ---- Software Used ---- STUI : 1.7.21 alerts : 2.3.0 boss : 6.0.3 -boss.specMec : 3.0.4 apo : 4.1.0 fliswarm : 0.5.1a0 jaeger : 1.10.3a1 kaiju : 1.4.1 coordio : 1.17.1a0 fps_calibrati : 2025.02.24+ccdaeaa cherno : 1.1.0 astrometrynet : 0.93 hal : 1.4.1 hartmann : 2.0.2 hub : 5.0.1a0 mcp : 2.3.1 -mcp.plc : 35 -mcp.azFiduci : v1_151 -mcp.altFiduc : v1_151 -mcp.rotFiduc : v1_151 tcc : 1.4.0 apogee : not available apogeecal : not available apogeeql : v1_7_0dev STUIAdditions : 3.1.18 boson : 0.5.1 sdss-obstools : 3.9.3 TPM : 1.2-31-gd7eb MCP : 2.3.1 PLC : V35 Fiducials : v1_151 idlspec2d : v6_2_1 Kronos : 2.1.0a roboscheduler : 2.1.0 ---- APOGEE Data Summary ---- 60960 morning cals: num field design config exptype dithpix nread relflux okay dx dy sigx sigy fpi1 fpi2 -------- ------ ------ ------ ------------ ------- ----- ------- ----- ------- ------- ------ ------ ---- ---- 53980011 -999 -999 21674 DARK 13.5 60 -27 True -- -- -- -- -- -- 53980012 -999 -999 21674 DARK 13.5 60 -8 True -- -- -- -- -- -- 53980013 -999 -999 21674 DARK 13.5 60 -13 True -- -- -- -- -- -- 53980014 -999 -999 21674 QUARTZFLAT 13.5 10 99 True -- 0.61 -- 0.86 -- -- 53980015 -999 -999 21674 QUARTZFLAT 13.5 10 99 True -- 0.62 -- 0.85 -- -- 53980016 -999 -999 21674 QUARTZFLAT 13.5 10 100 True -- 0.61 -- 0.85 -- -- 53980017 -999 -999 21674 ARCLAMP-THAR 13.5 12 95 True 23.33 1.25 1.06 0.92 -- -- 53980018 -999 -999 21674 ARCLAMP-UNE 13.5 40 4 True -10.91 -5.13 0.91 0.86 -- -- 53980019 -999 -999 21674 ARCLAMP-THAR 13.0 12 99 True 22.82 1.26 1.07 0.97 -- -- 53980020 -999 -999 21674 ARCLAMP-UNE 13.0 40 133 True 22.59 -5.12 1.04 0.92 -- -- 53980021 -999 -999 21674 DARK 13.0 30 3 False -- -- -- -- -- -- 53980022 -999 -999 21674 INTERNALFLAT 13.0 30 100 True -- -- -- -- -- -- 53980023 -999 -999 21674 INTERNALFLAT 13.0 30 101 True -- -- -- -- -- -- 53980024 -999 -999 21674 INTERNALFLAT 13.0 30 101 True -- -- -- -- -- -- 53980025 -999 -999 21674 DARK 13.0 30 260 True -- -- -- -- -- -- 53980026 -999 -999 21674 FPI 13.0 30 240 True 9.83 -5.18 1.11 0.89 -- -- 53980027 -999 -999 21674 FPI 13.5 30 237 True -1.97 -5.22 1.12 0.89 -- -- num exptype nread mtp1 mtp2 mtp3 mtp4 mtp5 mtp6 mtp7 mtp8 mtp9 mtp10 -------- ---------- ----- ---- ---- ---- ---- ---- ---- ---- ---- ---- ----- 53980014 QUARTZFLAT 10 66 70 81 90 90 85 88 89 89 82 53980015 QUARTZFLAT 10 70 74 82 91 91 86 89 90 89 83 53980016 QUARTZFLAT 10 71 75 83 92 91 87 89 90 90 84 (observers39) [observer@sdss5-hub: ~]$ check_ap 60961 num field design config exptype dithpix nread relflux okay dx dy sigx sigy fpi1 fpi2 -------- ----- ------ ------ ------------ ------- ----- ------- ---- ------- ------- ------ ------ ---- ---- 53990001 -999 -999 21674 DARK 13.5 3 0 True -- -- -- -- -- -- 53990002 -999 -999 21675 DARK 13.5 60 -15 True -- -- -- -- -- -- 53990003 -999 -999 21675 QUARTZFLAT 13.5 10 97 True -- 0.55 -- 0.86 -- -- 53990004 -999 -999 21675 ARCLAMP-THAR 13.5 12 97 True 23.35 1.27 1.07 0.97 -- -- 53990005 -999 -999 21675 ARCLAMP-UNE 13.5 40 3 True -10.57 -5.05 0.75 0.73 -- -- 53990006 -999 -999 21675 ARCLAMP-THAR 13.0 12 102 True 22.82 1.23 1.08 0.89 -- -- 53990007 -999 -999 21675 ARCLAMP-UNE 13.0 40 129 True 22.60 -5.20 1.01 0.81 -- -- 53990008 -999 -999 21675 DARK 13.0 60 -8 True -- -- -- -- -- -- 53990009 -999 -999 21675 FPI 13.0 30 236 True 9.83 -5.26 1.09 0.88 -- -- 53990010 -999 -999 21675 FPI 13.5 30 233 True -1.98 -5.29 1.11 0.90 -- -- num exptype nread mtp1 mtp2 mtp3 mtp4 mtp5 mtp6 mtp7 mtp8 mtp9 mtp10 -------- ---------- ----- ---- ---- ---- ---- ---- ---- ---- ---- ---- ----- 53990003 QUARTZFLAT 10 67 70 81 91 90 86 88 90 89 82 ---- BOSS Data Summary ---- Reading FITS from /data/spectro//60961 -
