APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday September 23, 2026 (SJD 61307) ---- Observing Team ---- Dmitry Bizyaev ---- Observing Plan ---- Wed 23 Sep 2026 61307 0.94 01:51 02:06 11:45 19:14 04:55 --- bright until 10:47 ( 8.9 h, w/ 0.2 h for 12 deg design), then dark ( 1.0 h) ---- Observing Summary ---- The entire night was lost to rain, fog, radars and high humidity. We had a few waves of really heavy rain. I looked at the enclosure's ceiling and didn't find any leaks other than the known place at the Southern corner - far off the telescope. Absorbent pads were placed in the lower enclosure where water got collected in some spots. ---- Observing Log ---- Afternoon ========= All systems checked and no problems noticed.

The second attempt of the evening APOGEE calibrations worked better: ------------------------------------------------------------------------------ mjd i UT File/Exp Imtype Nread A/B Dth Design-Cfg Arch Offset %Flux/FPI Comm ------------------------------------------------------------------------------ 61307 1 22:59 57450001 Arc---- 3 B 13.5 ---------- a-b-c - -6 test 61307 2 23:12 57450002 Dark 60 B 13.5 ---------- a-b-c - - 61307 3 23:13 57450003 QuarFlat 10 B 13.5 ---------- a-b-c - 104 cannot read file : /data/apogee/quickred/61307/apq-57450004.fits cannot read file : /data/apogee/utr_cdr/61307/apRaw-57450005.fits cannot read file : /data/apogee/utr_cdr/61307/apRaw-57450006.fits 61307 7 23:33 57450007 Arc---- 40 A 13.0 ---------- a-b-c - 19 61307 8 23:44 57450008 Dark 60 A 13.0 ---------- a-b-c - - 61307 9 23:49 57450009 Arc---- 30 A 13.0 ---------- a-b-c - 96 FPI A 61307 10 23:54 57450010 Arc---- 30 B 13.5 ---------- a-b-c - 95 FPI B 61307 11 00:09 57450011 QuarFlat 10 A 13.0 ---------- a-b-c - 103 61307 12 00:11 57450012 Arc-Thar 12 B 13.5 ---------- a-b-c 3.69 102 61307 13 00:18 57450013 Arc-Une 40 B 13.5 ---------- a-b-c 3.72 95 61307 14 00:20 57450014 Arc-Thar 12 A 13.0 ---------- a-b-c 3.12 103 61307 15 00:27 57450015 Arc-Une 40 A 13.0 ---------- a-b-c 3.16 97 ------------------------------------------------------------------------------ ===== Night ===== I was unable to open before sunset because of the rainy weather. 10:40Z calling it a night. num field design config exptype dithpix nread relflux okay dx dy sigx sigy fpi1 fpi2 -------- ----- ------ ------ ------------ ------- ----- ------- ----- ------- ------- ------ ------ ---- ---- 57450001 -999 -999 27789 ARCLAMP-None 13.5 3 0 False 0.00 0.00 0.00 0.00 0 0 57450002 -999 -999 27790 DARK 13.5 60 -33 True -- -- -- -- -- -- 57450003 -999 -999 27790 QUARTZFLAT 13.5 10 112 True -- 0.73 -- 0.85 -- -- 57450007 -999 -999 27790 DARK 13.0 40 70 True -- -- -- -- -- -- 57450008 -999 -999 27790 DARK 13.0 60 -2 True -- -- -- -- -- -- 57450009 -999 -999 27790 FPI 13.0 30 246 True 13.12 -5.11 1.12 0.91 -- -- 57450010 -999 -999 27790 FPI 13.5 30 243 True -11.04 -5.08 1.12 0.90 -- -- 57450011 -999 -999 27790 QUARTZFLAT 13.0 10 112 True -- 0.73 -- 0.85 -- -- 57450012 -999 -999 27790 ARCLAMP-THAR 13.5 12 1 True -1.96 -- 1.07 -- -- -- 57450013 -999 -999 27790 ARCLAMP-UNE 13.5 40 3 True -7.95 -- 1.11 -- -- -- 57450014 -999 -999 27790 ARCLAMP-THAR 13.0 12 1 True -2.58 -- 1.29 -- -- -- 57450015 -999 -999 27790 ARCLAMP-UNE 13.0 40 2 True -7.53 -- 0.30 -- -- -- 57450016 -999 -999 27790 DARK 13.0 60 -30 True -- -- -- -- -- -- 57450017 -999 -999 27790 DARK 13.0 60 -10 True -- -- -- -- -- -- 57450018 -999 -999 27790 DARK 13.0 60 -15 True -- -- -- -- -- -- 57450019 -999 -999 27790 QUARTZFLAT 13.0 10 117 True -- 0.81 -- 0.85 -- -- 57450020 -999 -999 27790 QUARTZFLAT 13.0 10 116 True -- 0.82 -- 0.85 -- -- 57450021 -999 -999 27790 QUARTZFLAT 13.0 10 118 True -- 0.81 -- 0.87 -- -- 57450022 -999 -999 27790 ARCLAMP-THAR 13.5 12 1 True -1.99 -- 1.33 -- -- -- 57450023 -999 -999 27790 ARCLAMP-UNE 13.5 40 4 True -7.73 -5.03 1.19 0.77 -- -- 57450024 -999 -999 27790 ARCLAMP-THAR 13.0 12 0 True -2.48 -5.06 1.04 0.93 -- -- num exptype nread mtp1 mtp2 mtp3 mtp4 mtp5 mtp6 mtp7 mtp8 mtp9 mtp10 -------- ---------- ----- ---- ---- ---- ---- ---- ---- ---- ---- ---- ----- 57450003 QUARTZFLAT 10 71 82 90 100 100 95 97 99 99 91 57450011 QUARTZFLAT 10 72 83 90 100 100 95 96 98 99 91 57450019 QUARTZFLAT 10 70 81 89 100 100 95 96 98 99 90 57450020 QUARTZFLAT 10 74 84 91 101 100 95 96 98 99 92 57450021 QUARTZFLAT 10 74 85 91 101 100 95 96 98 99 92 ---- Mirror Numbers ---- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A: -5.4260 -5.4260 Axial B: -5.0390 -5.0390 Axial C: -5.2790 -5.2780 Trans D: -0.8710 -0.8710 Lateral E: 0.3245 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: -1.06 -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: -6.1140 -6.1140 Axial C: -6.0770 -6.0790 Trans D: 0.2060 0.2050 GALILS Commanded: 362600 385300 341950 -1500 1800 Actual: 321920 349945 299571 -1500 1800 SETMIR VALUES SecDesOrient: 257.0 14.2 5.9 -72.0 -12.76 SecOrient: 256.97 14.19 5.88 -71.8 -12.62 ---- Telescope Status ---- Not opened.
