APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday October 19, 2026 (SJD 61333) ---- Observing Team ---- Audrey Oravetz ---- Observing Plan ---- Mon 19 Oct 2026 61333 0.65 01:19 01:33 12:03 20:24 06:55 --- bright until 07:32 ( 6.2 h, w/ 0.2 h for 12 deg design), then dark ( 4.5 h) ---- Observing Summary ---- The weather was decent enough to open at sunset and gather APOGEE twilight flats (though I may have started them slightly late as the counts amounted to ~10k instead of the targeted 12-20k). Afterwards, the humidity spiked and set us close to the 2.5 dewpoint difference limit. We stayed opened long enough to get one exposure set on a bright design before closing. Not long after we closed, a wild thunderstorm hit from the west. I placed absorbent pads down in the enclosure before it hit. We had patches of clear sky after the storm passed, but the humidity remained elevated and low clouds with radar blips would appear just to the west. We unfortunately never had a good chance to reopen. ---- Automatic Summary ---- Time Field-Design-Conf DesignType BOSS/APOGEE Seeing Overhead Complete?

It is an annoyance and sets us back 5-10 minutes. ---- Observing Log ---- Afternoon: ========== 21:06:33 boss exposure 0.0, file=405487 21:07:58 boss exposure 20.0, file=405488 21:09:45 boss exposure 4.0, file=405489 21:10:26 boss exposure 4.0, file=405490 21:11:11 sp1.motor.move= 2628, 2628, 2628 21:11:11 Hartmann collimate output sp1: offset: r= 1979 (Out of focus); b= -10.3 (Out of focus) sp1: pred. move: spAverageMove= 2628 sp1: pred. resid: r= -649, b= -2.0, txt= OK, spTemp = 7.8 21:11:48 boss exposure 4.0, file=405491 21:14:11 boss exposure 25.0, file=405492 21:14:15 Config Loaded: -999-27992 21:15:17 jaeger.jaeger 187 fliswarm i filename_bundle=/data/fcam/61333/fimg-fvc1n-0001.fits 21:15:17 jaeger.jaeger 187 fliswarm : 21:15:17 CmdDone: jaeger.jaeger 187 fliswarm talk -c fvc expose 5.0 21:16:32 APO.aoravetz2 40 fliswarm i filename_bundle=/data/fcam/61333/fimg-fvc1n-0002.fits 21:16:32 APO.aoravetz2 40 fliswarm : 21:16:32 CmdDone: APO.aoravetz2 40 fliswarm talk -n fvc expose 50 jaeger configuration random --danger 21:18:26 Jaeger collision: 932 jaeger configuration reverse (observers39) [observer@sdss5-hub: ~]$ list_ap APOGEE data list, mjd=61333, all raw_data: /data/apogee/utr_cdr/61333/apRaw-*.fits archive: /data/apogee/archive/61333/apR-[a,b,c]-*.apz quickred: /data/apogee/quickred/61333/apq-*.fits ------------------------------------------------------------------------------ mjd i UT File/Exp Imtype Nread A/B Dth Design-Cfg Arch Offset %Flux/FPI Comm ------------------------------------------------------------------------------ 61333 1 21:17 57710001 Dark 60 B 13.5 ---------- a-b-c - - 61333 2 21:18 57710002 QuarFlat 10 B 13.5 ---------- a-b-c - 100 61333 3 21:21 57710003 Arc-Thar 12 B 13.5 ---------- a-b-c 3.90 103 61333 4 21:28 57710004 Arc-Une 40 B 13.5 ---------- a-b-c 3.92 94 61333 5 21:30 57710005 Arc-Thar 12 A 13.0 ---------- a-b-c 3.33 102 61333 6 21:37 57710006 Arc-Une 40 A 13.0 ---------- a-b-c 3.38 96 61333 7 21:48 57710007 Dark 60 A 13.0 ---------- a-b-c - - 61333 8 21:54 57710008 Arc---- 30 A 13.0 ---------- a-b-c - 96 FPI A 61333 9 21:59 57710009 Arc---- 30 B 13.5 ---------- a-b-c - 94 FPI B fliswarm talk -c gfa expose --bias --count 10 fliswarm talk -c gfa expose --dark --count 5 5 fliswarm talk -c gfa expose --flat 1 00:00Z - Started ventilating.
