APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday October 09, 2025 (SJD 60958) ---- Observing Team ---- Dan Oravetz ---- Observing Plan ---- Thu 09 Oct 2025 60958 dark until 02:18 (0.6 h), then bright (10.1 h, w/ 0.4 h for 12 deg design) ---- Observing Summary ---- Persistent humidity and unforecasted clouds kept us closed tonight. The clouds were unpredictable and low, and encroached from different directions, sometimes with an associated mist or a light drizzle that was sufficient to trigger the rain sensor. ---- Observing Log ---- ============================================================================ AFTERNOON CHECKOUT ============================================================================ All systems alive and responsive.

Mostly cloudy, but not actively raining, so probably just some fog or quick drizzle. There are radar returns associated with the clouds encroaching from the south, though. 07:13Z - It's less cloudy overhead, but this is a sucker hole and the clouds encroaching from the south will worsen the sky conditions soon. Of course, humidity is still an issue, too. 11:16Z - Called it a night. Morning cals started. FPS powered-off. Positioners are home/folded. ---- 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: -0.0310 -0.0280 Lateral E: 0.3400 0.3400 Lateral F: 0.5455 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: -7.5380 -7.5410 Axial C: -7.5310 -7.5320 Trans D: 0.1800 0.1800 GALILS Commanded: 2249550 2247000 2244750 -1750 -1750 Actual: 2215685 2225449 2199288 -1750 -1750 SETMIR VALUES SecDesOrient: 1757.0 7.9 1.5 -39.3 35.42 SecOrient: 1756.94 7.92 1.45 -38.75 35.75 ---- 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 balance LN2 autofill systems: Connected and turned on 180L LN2 dewar scales: SP1 275 lbs, 20 psi FPS Status ========== CP10 Loop = 7.58 L/min GFA Loop = 2.27 L/min Supply pressure = 44.4 psi Return pressure = 29.8 psi Chiller Status ============== Set temperarature = 13.0 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 ---- 60957 morning cals: num field design config exptype dithpix nread relflux okay dx dy sigx sigy fpi1 fpi2 -------- ----- ------ ------ ------------ ------- ----- ------- ----- ------- ------- ------ ------ ---- ---- 53950011 -999 -999 21660 DARK 13.5 60 -20 True -- -- -- -- -- -- 53950012 -999 -999 21660 DARK 13.5 60 -27 True -- -- -- -- -- -- 53950013 -999 -999 21660 DARK 13.5 60 -3 True -- -- -- -- -- -- 53950014 -999 -999 21660 QUARTZFLAT 13.5 10 100 True -- 0.64 -- 0.86 -- -- 53950015 -999 -999 21660 QUARTZFLAT 13.5 10 101 True -- 0.62 -- 0.86 -- -- 53950016 -999 -999 21660 QUARTZFLAT 13.5 10 100 True -- 0.64 -- 0.85 -- -- 53950017 -999 -999 21660 ARCLAMP-THAR 13.5 12 95 True 23.33 1.27 1.06 0.82 -- -- 53950018 -999 -999 21660 ARCLAMP-UNE 13.5 40 3 True -11.02 -5.23 0.85 0.79 -- -- 53950019 -999 -999 21660 ARCLAMP-THAR 13.0 12 100 True 22.81 1.24 1.07 0.88 -- -- 53950020 -999 -999 21660 ARCLAMP-UNE 13.0 40 139 True 22.60 -5.18 1.01 0.87 -- -- 53950021 -999 -999 21660 DARK 13.0 30 3 False -- -- -- -- -- -- 53950022 -999 -999 21660 INTERNALFLAT 13.0 30 100 True -- -- -- -- -- -- 53950023 -999 -999 21660 INTERNALFLAT 13.0 30 101 True -- -- -- -- -- -- 53950024 -999 -999 21660 INTERNALFLAT 13.0 30 101 True -- -- -- -- -- -- 53950025 -999 -999 21660 DARK 13.0 30 253 True -- -- -- -- -- -- 53950026 -999 -999 21660 FPI 13.0 30 252 True 9.82 -5.15 1.10 0.88 -- -- 53950027 -999 -999 21660 FPI 13.5 30 252 True -1.99 -5.19 1.12 0.90 -- -- num exptype nread mtp1 mtp2 mtp3 mtp4 mtp5 mtp6 mtp7 mtp8 mtp9 mtp10 -------- ---------- ----- ---- ---- ---- ---- ---- ---- ---- ---- ---- ----- 53950014 QUARTZFLAT 10 67 71 81 90 90 87 88 89 89 82 53950015 QUARTZFLAT 10 70 74 82 91 91 88 89 90 90 84 53950016 QUARTZFLAT 10 71 75 83 92 91 88 89 90 90 84 (observers39) [observer@sdss5-hub: ~]$ check_ap 60958 num field design config exptype dithpix nread relflux okay dx dy sigx sigy fpi1 fpi2 -------- ----- ------ ------ ------------ ------- ----- ------- ---- ------- ------- ------ ------ ---- ---- 53960001 -999 -999 21660 DARK 13.5 3 67 True -- -- -- -- -- -- 53960002 -999 -999 21661 DARK 13.5 60 5 True -- -- -- -- -- -- 53960003 -999 -999 21661 QUARTZFLAT 13.5 10 98 True -- 0.55 -- 0.86 -- -- 53960004 -999 -999 21661 ARCLAMP-THAR 13.5 12 99 True 23.35 1.24 1.06 0.87 -- -- 53960005 -999 -999 21661 ARCLAMP-UNE 13.5 40 4 True -10.91 -5.18 0.99 0.96 -- -- 53960006 -999 -999 21661 ARCLAMP-THAR 13.0 12 104 True 22.82 1.19 1.08 0.91 -- -- 53960007 -999 -999 21661 ARCLAMP-UNE 13.0 40 134 True 22.59 -5.35 1.04 0.87 -- -- 53960008 -999 -999 21661 DARK 13.0 60 -2 True -- -- -- -- -- -- 53960009 -999 -999 21661 FPI 13.0 30 248 True 9.81 -5.26 1.11 0.89 -- -- 53960010 -999 -999 21661 FPI 13.5 30 244 True -1.99 -5.31 1.11 0.89 -- -- num exptype nread mtp1 mtp2 mtp3 mtp4 mtp5 mtp6 mtp7 mtp8 mtp9 mtp10 -------- ---------- ----- ---- ---- ---- ---- ---- ---- ---- ---- ---- ----- 53960003 QUARTZFLAT 10 67 72 82 91 91 87 89 90 90 82 ---- BOSS Data Summary ---- Reading FITS from /data/spectro//60958 -
