APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday June 02, 2026 (SJD 61194) ---- Observing Team ---- Dan Oravetz ---- Observing Plan ---- Tue 02 Jun 2026 61194 dark until 04:31 (1.1 h), then bright (7.3 h, w/ 1.3 h for 8 deg design) ---- Observing Summary ---- Lots of clouds again tonight and some periods of light rain, in addition to some impressive lightning displays during the middle of the night. The first large weather system slowly moved east and northeast throughout the night, but never sufficiently cleared out before the next one pushed its way into the region from our south. We did not get on sky. ---- Observing Log ---- ============================================================================ AFTERNOON CHECKOUT ============================================================================ All systems alive and responsive.

Impressive lightning display, but only light rain. 09:28Z - The next storm to the south has grown bigger and is in the county to our south. We still have clouds remaining from the earlier system, but now this one has encroached and will soon take its place. There is a sucker hole potentially, but it is much too small to risk opening at this point (and not to mention the lightning in it is intimidating). 10:01Z - 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: 0.0080 0.0030 Axial B: -0.0250 -0.0300 Axial C: -0.0200 -0.0280 Trans D: -0.0140 -0.0230 Lateral E: 0.3400 0.3400 Lateral F: 0.5475 0.5475 GALILS Commanded: 8450 -1050 8800 22100 -2000 -1700 Actual: 8450 -1050 8800 22100 -2000 -1700 SETMIR VALUES PrimDesOrient: 0.0 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: -7.6400 -7.6400 Axial B: -7.5350 -7.5350 Axial C: -7.5310 -7.5270 Trans D: 0.2010 0.1960 GALILS Commanded: 2241550 2237200 2234100 -1800 -1750 Actual: 2215622 2225348 2199389 -1800 -1750 SETMIR VALUES SecDesOrient: 1757.0 7.9 1.5 -39.3 35.42 SecOrient: 1756.91 7.89 1.47 -39.32 36.36 ---- Telescope Status ---- Status at close: Telescope stowed at: 121.0, 30.0, 0.0 mount Instrument mounted: FPS Counterweights at: manually adjusted for telescope balance w/ FPS LN2 autofill systems: Connected and turned on 180L LN2 dewar scales: SP1 286 lbs, 23 psi FPS Status ========== CP10 Loop = 7.48 L/min GFA Loop = 2.43 L/min Supply pressure = 44.2 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 : 6.0.5a1 -boss.specMec : 3.0.4 apo : 4.1.0 fliswarm : 0.6.0 jaeger : 1.11.2a1 kaiju : 1.4.1 coordio : 1.18.1 fps_calibrati : 2025.12.04 cherno : 1.2.2 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_153 -mcp.altFiduc : v1_153 -mcp.rotFiduc : v1_153 tcc : 1.4.0 apogee : not available apogeecal : not available apogeeql : v1_7_0dev boson : 0.6.1 sdss-obstools : 3.9.3 TPM : 1.2-31-gd7eb MCP : 2.3.1 PLC : V35 Fiducials : v1_153 idlspec2d : v6_2_1 Kronos : 2.1.0a roboscheduler : 2.1.0 ---- APOGEE Data Summary ---- Morning cals ============ (observers39) [observer@sdss5-hub: ~]$ check_ap 61193 num field design config exptype dithpix nread relflux okay dx dy sigx sigy fpi1 fpi2 -------- ------ ------ ------ ------------ ------- ----- ------- ----- ------- ------- ------ ------ ---- ---- 56310011 -999 -999 26842 DARK 13.5 60 -18 True -- -- -- -- -- -- 56310012 -999 -999 26842 DARK 13.5 60 -13 True -- -- -- -- -- -- 56310013 -999 -999 26842 DARK 13.5 60 -10 True -- -- -- -- -- -- 56310014 -999 -999 26842 QUARTZFLAT 13.5 10 113 True -- 0.77 -- 0.86 -- -- 56310015 -999 -999 26842 QUARTZFLAT 13.5 10 114 True -- 0.78 -- 0.85 -- -- 56310016 -999 -999 26842 QUARTZFLAT 13.5 10 114 True -- 0.76 -- 0.86 -- -- 56310017 -999 -999 26842 ARCLAMP-THAR 13.5 12 1 True -3.49 -4.96 1.19 0.94 -- -- 56310018 -999 -999 26842 ARCLAMP-UNE 13.5 40 2 True -9.24 -5.02 0.75 0.96 -- -- 56310019 -999 -999 26842 ARCLAMP-THAR 13.0 12 1 True -4.02 -5.00 1.54 0.91 -- -- 56310020 -999 -999 26842 ARCLAMP-UNE 13.0 40 2 True -9.57 -5.02 0.31 0.85 -- -- 56310021 -999 -999 26842 DARK 13.0 30 7 False -- -- -- -- -- -- 56310022 -999 -999 26842 INTERNALFLAT 13.0 30 96 True -- -- -- -- -- -- 56310023 -999 -999 26842 INTERNALFLAT 13.0 30 96 True -- -- -- -- -- -- 56310024 -999 -999 26842 INTERNALFLAT 13.0 30 97 True -- -- -- -- -- -- 56310025 -999 -999 26842 DARK 13.0 30 260 True -- -- -- -- -- -- 56310026 -999 -999 26842 FPI 13.0 30 241 True -0.77 -5.06 1.08 0.89 -- -- 56310027 -999 -999 26842 FPI 13.5 30 245 True 12.04 -5.04 1.11 0.89 -- -- num exptype nread mtp1 mtp2 mtp3 mtp4 mtp5 mtp6 mtp7 mtp8 mtp9 mtp10 -------- ---------- ----- ---- ---- ---- ---- ---- ---- ---- ---- ---- ----- 56310014 QUARTZFLAT 10 74 81 90 101 100 95 97 99 99 91 56310015 QUARTZFLAT 10 77 84 91 102 100 95 97 99 100 92 56310016 QUARTZFLAT 10 78 84 91 102 101 95 97 99 100 93 (observers39) [observer@sdss5-hub: ~]$ list_ap -m 61193 APOGEE data list, mjd=61193, all raw_data: /data/apogee/utr_cdr/61193/apRaw-*.fits archive: /data/apogee/archive/61193/apR-[a,b,c]-*.apz quickred: /data/apogee/quickred/61193/apq-*.fits ------------------------------------------------------------------------------ mjd i UT File/Exp Imtype Nread A/B Dth Design-Cfg Arch Offset %Flux/FPI Comm ------------------------------------------------------------------------------ 61193 11 10:43 56310011 Dark 60 B 13.5 ---------- a-b-c -
