Subject: 2.5m obslog 20190616 (SJD 58651) From: kpan@apo.nmsu.edu Date: Mon, 17 Jun 2019 11:56:52 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday June 16, 2019 (SJD 58651) ---- Observing Team ---- Karen Kinemuchi Kaike Pan Dylan Gatlin (observer candidate) ---- Observing Plan ---- Sun 16 JUN 2019 58651.0 1.00 02:55 11:15 13:32 21:54 Night APOGEE-2 ( 8.3 h) ---- Observing Summary ---- The nights was clouded out except for the last 2.5 hours which was partly cloudy with poor seeing. 5.8 hours engineering/APOGEE time was lost to weather. We tested the new Gaia catalog. No problem in slewing the telescope to pterr stars. However, it seems that the neighbor rejection doesn't work. We took images of five pterr stars for magnitude of 12.5 to 12.7, and found there are 2-4 stars with similar brightness (within 1 mag or so). within 60 arcsecond (images /data/ecam/58651/gimg.0020 - 50). We tried to take a 20-point pointing model, the telescope quickly ran away (at 4th stars) with calib offsets of 2 arc minutes in Az, 4 arc minutes in alt. Then we switched back to the old catalog and replaced filters with the old combination (Guider filter + N64). Notes: ===== 1. The rotator oscillated about 0.5 degree when slew from 121,70,0.0 to 121,30,0.0 at 02:43Z. The next slew worked fine (see log for more info). 2. Racoon waste was found on the base of the engineering camera, cleaned and disinfected the base and cables around. No damage on cables are found. Because cables are not covered there, should we leave the engineering camera on a dolly instead of put it in the bay? 3. New catalog needs more work. See above. 4. Dust: 3K. ---- Observing Log ---- Mostly clear with some clouds. Radar to the north and west of us.

Then, we found a unpleasing surprising: racoon waste on the base of the engineering camera, we cleaned and disinfected the base and cables. 02:43Z: after mounted the engineering camera, connected cables, we slow the tescope from 121,70, 0 to the stow, noticed that the rotator oscillated forward and back, a axis stop was issued immediated, and stop bottom was engaged. The rotator was found stopped at 17 arc-minutes. The next goto stow wored normally. 02:48Z: enclosure open. After open, we setup the engineering camera, took dark, and flat. Looked like that 0.3 to 0.4 s is a good exposure time for the ecamera flat (without any filter). it was cloudy, so we homed/relaxed M1 again since the F actuator was off after the afternoon home/relax. We relax M1 3 times. The Mirror numbers are fine after the 2nd home/relax. it was overcast, we could not see the moon. We slow the telescope to three stars with the new stars, slews are fine although we didn't see stars due to clouds. 05:27Z: radar approached us, close. 08:45Z: the sky got slightly better, open again. It was very cloudy, but could see a couple of stars. We focused the engineering camera. Seeing was poor at 2.5 - 3.5'. Anyway, we slow to couple of stars with the new Gaia star catalog, an took some images. No problem in slewing the telescope to pterr stars. However, it seems that the neighbor rejection doesn't work. We took images of five pterr stars for magnitude of 12.5 to 12.7, and found there are 2-4 stars with similar brightness (within 1 mag or so). within 60 arcsecond (images /data/ecam/58651/gimg.0020 - 50). We tried to take a 20-point pointing model, the telescope quickly ran away (at 4th stars) with calib offsets of 2 arc minutes in Az, 4 arc minutes in alt. We switched back to the old catalog, restarted tcc, and replaced filters with the old combination (Guider filter + N64). retook engCam flat with a 50 sec exposure time. started a 20-point pointing model, let's completed until 11:30Z. Because the seeing was very poor, the data was not good, but the sequence completed normally, so we think that we are set for tomorrow's pointing model. 11:40Z: closed. 11:48Z: started morning calib. ---- Mirror Numbers ---- PRIMARY: -------- Scale: 1.000000; MIGS TONIGHT NOMINAL Axial A: -5.316 -5.318 Axial B: -5.072 -5.073 Axial C: -5.335 -5.337 Trans D: 10.74 10.737 Lateral E: 9.0805 9.0805 Lateral F: 14.2113 14.1859 GALILS Commanded: 10250 -1100 7100 16850 12400 12400 Actual: 10250 -1100 7100 16850 12400 12400 SETMIR VALUES PrimDesOrient: 0.0 3.27 2.1 115.0 -178.65 PrimOrient: -1.06 3.29 2.19 115.07 -177.78 SECONDARY: ---------- Focus: 0.0000 Air temp: 21.6 Altitude: 30.0 MIGS TONIGHT NOMINAL Axial A: -0.908 -0.907 Axial B: -0.909 -0.908 Axial C: -0.298 -0.296 Trans D: -0.103 -0.101 GALILS Commanded: 1120800 1125450 1083650 -5700 -7450 Actual: 1086025 1106939 1046315 -5700 -7450 SETMIR VALUES SecDesOrient: 857.0 18.54 2.85 -17.2 138.98 SecOrient: 856.92 18.57 2.82 -16.99 138.77 Mirror numbers after Home/Relax process for M1 and M2: PRIMARY: -------- Scale: 1.000000; MIGS TONIGHT NOMINAL Axial A: -5.317 -5.318 Axial B: -5.071 -5.073 Axial C: -5.336 -5.337 Trans D: 10.738 10.737 Lateral E: 9.0805 9.0805 Lateral F: 13.97 14.1859 GALILS Commanded: 10250 -1100 7100 16850 12400 12400 Actual: 10250 -1100 7100 16850 12400 12400 SETMIR VALUES PrimDesOrient: 0.0 3.27 2.1 115.0 -178.65 PrimOrient: -1.06 3.29 2.19 115.07 -177.78 SECONDARY: ---------- Focus: 0.0000 Air temp: 17.5 Altitude: 30.0 MIGS TONIGHT NOMINAL Axial A: -0.905 -0.907 Axial B: -0.906 -0.908 Axial C: -0.295 -0.296 Trans D: -0.102 -0.101 GALILS Commanded: 1123400 1127750 1084250 -5750 -7400 Actual: 1086000 1107071 1046466 -5750 -7400 SETMIR VALUES SecDesOrient: 857.0 18.54 2.85 -17.2 138.98 SecOrient: 856.99 18.52 2.87 -18.1 138.8 PRIMARY: -------- Scale: 1.000000; MIGS TONIGHT NOMINAL Axial A: -5.316 -5.318 Axial B: -5.074 -5.073 Axial C: -5.333 -5.337 Trans D: 10.735 10.737 Lateral E: 9.0805 9.0805 Lateral F: 14.1859 14.1859 GALILS Commanded: 10250 -1100 7100 16850 12400 12400 Actual: 10250 -1100 7100 16850 12400 12400 SETMIR VALUES PrimDesOrient: 0.0 3.27 2.1 115.0 -178.65 PrimOrient: -1.06 3.29 2.19 115.07 -177.78 SECONDARY: ---------- Focus: 0.0000 Air temp: 14.6 Altitude: 30.0 MIGS TONIGHT NOMINAL Axial A: -0.907 -0.907 Axial B: -0.909 -0.908 Axial C: -0.297 -0.296 Trans D: -0.1 -0.101 GALILS Commanded: 1116800 1123550 1079450 -5750 -7450 Actual: 1085931 1107020 1046372 -5750 -7450 SETMIR VALUES SecDesOrient: 857.0 18.54 2.85 -17.2 138.98 SecOrient: 856.9 18.51 2.83 -17.55 139.38 ---- Telescope Status ---- 00:40Z Started ventilation 02:48, 8:58Z encl25m : open 05:28Z, 11:30Z encl25m : closed No interlocks bypassed Status at: 12:00Z Telescope stowed at: 121.0, 30.0, 0.0 mount Instrument mounted: cartridge = engCam Counterweights at: 340 LN2 autofill systems: Connected and turned on 180L LN2 dewar scales: SP1 153 lbs, 21.3 psi SP2 166 lbs, 22.8 psi ---- Software Used ---- Get Versions, 06/17/19, 00:01:22 -- STUI software: STUI : 1.7.8 alerts : trunk apo : trunk boss : v4_0 -boss.specMec : 3.0.4 gcamera : v2_2 guider : 3.8.1 hartmann : 1.6.0 hub : Tag: v4.2 mcp : v7_0_4 -mcp.plc : 34 -mcp.azFiduci : v1_137 -mcp.altFiduc : v1_137 -mcp.rotFiduc : v1_137 platedb : 2.8.0 sop : 3.12.3 tcc : 1.3.1 apogee : not availble apogeecal : not availble apogeeql : v1_6_1 APO-local : trunk -- done -- Home Disk Hogs (GB): muna 132.068 eboss 83.9934 manga 68.6892 sdss3 27.1813 apogee 17.7115 logging 13.7059 observer 10.8703 Filesystem Size Used Avail Use% Mounted on /dev/vdd 688G 629G 59G 92% /home /dev/vdc1 11T 9.3T 1.6T 86% /data Setting up: idlspec2d Flavor: Linux64 Version: v5_7_12 Setting up: |elodie Flavor: Linux64 Version: v1_3 Setting up: |spinspect Flavor: Linux64 Version: trunk Setting up: |specflat Flavor: Linux64 Version: v1_20 Setting up: |speclog Flavor: Linux64 Version: trunk Setting up: |platelist Flavor: Linux64 Version: trunk Setting up: |sdss_python_module Flavor: Linux64 Version: v1_6_7 Setting up: |sqlalchemy Flavor: Linux64 Version: 0.9.7 Setting up: |psycopg2 Flavor: Linux64 Version: 2.5.3 Setting up: |idlutils Flavor: Linux64 Version: v5_5_16 Setting up: |idl Flavor: Linux64 Version: 7.1 Setting up: |dust Flavor: Linux64 Version: v0_1 Setting up: |photolog Flavor: Linux64 Version: trunk Setting up: actorcore Flavor: Linux64 Version: v4_1_6 Setting up: |opscore Flavor: Linux64 Version: v2_5 Setting up: |external Flavor: Linux64 Version: v1_2_0 Setting up: |actorkeys Flavor: Linux64 Version: trunk Setting up: |plc Flavor: Linux64 Version: v30_2 Setting up: |sdsstools Flavor: Linux64 Version: v4_33 Setting up: |sdss3tools Flavor: Linux64 Version: v1_7_13 Setting up: |RO Flavor: Linux64 Version: 3.6.9 -- Other versions ---- idlspec2d : v5_7_12 plate-mapper3 : NOCVS:v6_0_12 petunia : git autoscheduler : 1.2.0 sdss_python_module: trunk mangadrp : trunk exported
