APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday November 11, 2005 (MJD 53686) ---=== OBSERVING TEAM ===--- Swing: Olena Malanushenko Viktor Malanushenko Steph Snedden Night: John Barentine Visitors: Kaike Pan Jurek Krzesinksi Support: John Marriner (FNAL) Kurt Biery (by phone) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- After a windy and dusty start, we proceeded to image the SN Stripe 82 N from 123 < lambda < -125 with an interruption of 40 degrees (+/- 20 degrees from the Moon's position at RA=0, lambda=175). Per Jim's instructions this was split into two separate runs. We experienced DA problems (see Log) during all this, recovered, and finished the night with Legacy Stripe 17 N from -66 < lambda < -29. Quality of the SN data is acceptable, but a good part of 17 N did not meet survey quality for seeing. We need some guidance from the reduction folks as to whether, if any, of this stripe is useful. After the problems with the DA, no new information (weather, focus, offsets, imaging details, skippy, etc.) made it into the log. I restarted IOP under the current version after reverting to astroDa v15_6, but nothing past about 05:40Z appeared. I filled in some information by hand, but monitored skippy and focus throughout the night to make sure we remained in spec. ---=== OBSERVING LOG ===--- Afternoon --------- No issues. Night ----- The evening started very windy and dusty, with both over the limit at sunset plus clouds. Toward 02:00Z things were calming down, with both winds and dust diminishing. I ventilated around this time. Given the wind direction, WSW, a spike in winds would bring more dust so I waited in hopes the wind would come down further. 03:18Z Run 5864 (SN Stripe 82 N, startLambda=123). The az and alt axes aborted on the scanStripe; not clear why, but I re-initialized the axes and carried on. Guessed -200 for the focus based on last night's numbers but got that quite wrong; adjusted upward to +25 before it looked at all reasonable. Skippy happy from the start, in focus by frame 15. Seeing was not too good, around 2 arcsec, and the sky was not quite photometric but otherwise clear. Around 03:55Z, ad4 appears to have died. I got a watcher error and then the monitor corresponding to that node went solid blue. Shortly thereafter, the other astrometric monitors stopped scrolling but watcher never threw errors. Knowing that with less than 100 frames having been taken this run would be thrown away (but having no other choice), I stopped the drift at 04:00 (lambda=134, RA=319, didn't catch the frame number before it disappeared.) Also, shortly before the astro nodes crashed, it appears that the teamster had died within about the previous 15 minutes. I restarted it before the node crash. Rebooted the astro crates at 04:01Z. 04:05Z Run 58645 (SN Stripe 82 N, startLambda=131). Immediately had a skippy problem on starting this scan (see Problems) and called both Steph and Kurt to let them know what was up. I was entirely unable to get a skippy result yet decided in consulation with Steph to keep going since 1) the skippy results from the previous run showed that the pointing was good, and 2) the move to back up between stripes was very small. I also noticed that focusLoop had stopped running; Steph confirmed that it was getting bogus information and therefore not updating telescope focus. At the time, seeing was not at all good, > 2.5 arcsec, so figuring out whether focus was indeed drifting was not easy. Still, in principle it could be nudged by hand as needed. Began the ramp down 20 degrees from the Moon at RA=340, lambda=155, Frame 176, 05:40Z. Ended the drift at RA=343, lambda=158, Frame 187. At this point, on consultation with Kurt, I attempted a revert to both the pre-shakeup versions of IOP and astroDa, per Kurt's instructions over the phone and his detailed procedure in the shakeup plan for reverting astroDa. This took two attempts. On the first attempt I was unable to get the murmur server to come back up after the reboots. Trying the procedure again, I got it to work the second time around. 06:32Z Run 5866 (SN Stripe 82 N, startLambda=-168) Started at a lambda such that science would begin 20 degrees E of the Moon. Skippy happy from the get-go; in focus by frame 20. Sky stayed solidly photometric throughout this run and seeing improved to survey-quality. Ramp down began at 09:22Z (lambda=-125, RA=60, Frame 292) and the drift ended at With ~30 minutes until moonset and steady seeing below the survey threshold, we elected to wait for the moon to go down and continue imaging. Off to Legacy to fill the remainder of the night... 09:54Z Run 5867 (Legacy Stripe 17 N, startLambda =-66) Did a 3 degree ramp into science. The moon set during the ramp at 09:58Z. In focus and skippy happy from the start and throughout this run. Seeing, as if on cue, started to blow up almost immediately around 10:15Z (Frame 45). seeingRun called it bad from Frame 28 (lambda=-62.9) to Frame 139 (lambda=-46.3), then acceptable to Frame 179 (lambda=-40.3) and good thereafter. I pushed 15 minutes past twilight but did not have quite enough time to reach the end of this stripe. The data may or may not be useful because of the ~150 frames seeingRun called bad/acceptable. Ended the drift at 12:21Z, Frame 25, lambda=-29. Closed up for the night at 12:40Z. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5862 22:40Z 00:20Z 100 O 100.33 125.35 54 ignore 5863 00:21Z 00:37Z 100 O 125.70 129.66 41 bias 5864 03:18Z 04:00Z 82 N 123.31 134.02 86 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- 5864 53 4 108 1.300 0.147 -2.600 0.173 -0.01806 243 35 ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ 5864 29 1 35 297 55 -1.790 0.269 0.530 0.209 -0.00178 5864 29 1 35 297 50 -1.790 0.356 0.897 0.190 -0.00301 5864 29 1 35 297 56 -1.850 0.305 0.910 0.183 -0.00306 5864 29 1 35 297 64 -1.983 0.282 1.258 0.252 -0.00423 5864 29 1 35 297 53 -2.049 0.325 1.321 0.235 -0.00444 ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 34849, plate -9999 ------- 22:23 34849 0.0 bias ----- sequence 34850, plate 2060 ------- 22:30 34850 10.0 flat 22:33 34851 2.0 arc 22:40 34852 2.1 arc 22:42 34853 2.1 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 03:25Z imager 296.90 0.0000 35.32 0.0000 41.19 0.0000 1.000000 09:11Z imager -42.71 0.0000 48.93 0.0000 55.04 0.0000 1.000000 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL Stays: JL ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 03:25Z imager 1.00000 0 -0 30 297 35.3 6.3 24 272 -- 2.0 09:11Z imager 1.00000 0 -210 -130 -43 48.9 3.1 11 265 -- 1.5 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:04Z 51 30 29 211 (SSW) 2966 - 22:34Z 54 27 37 238 (WSW) 6160 - 23:07Z 53 23 37 253 (WSW) 7993 - 23:37Z 50 22 32 232 (SW) 8099 - 00:07Z 49 22 36 235 (SW) 6406 - 01:00Z 48 23 23 251 (WSW) 4729 - 01:32Z 46 18 23 274 (W) 3450 - 02:04Z 45 12 20 264 (W) 1344 - 02:36Z 44 11 27 263 (W) 922 - 03:06Z 44 11 16 271 (W) 927 - 03:36Z 43 13 17 271 (W) 1292 - 04:07Z 42 14 20 278 (W) 1128 - 04:37Z 41 14 19 284 (WNW) 843 - 05:11Z 41 12 20 293 (WNW) 783 - 05:43Z 41 14 14 273 (W) 733 - ---=== TELESCOPE STATUS ===--- 01:55Z Fans on, louvers open, doors cracked 02:50Z Enclosure off 12:40Z Enclosure on, louvers and doors closed, fans off Telescope parked at 121,30 with Cart 7 (Plate 2060) mounted Counterweights at 250 Spectro autofill reconnected No interlocks bypassed Dewar weights at 13:15Z Imager: 152lbs 20psi Spectro: 247lbs 18psi ---=== SOFTWARE USED ===--- IOP/SOP: v4_6_1a and v4_6_0b Watcher: v2_30_2 MCP: v5_26_0 TPM: tpm_v3_1_0 AstroDa: v15_7 and v15_6 TCC: 2.7.2.1 sdssProcedures: v2_06 SoS: v4_10_7 hoggPT: v1_6_9 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A -5.8400 -5.8440 Axial B -5.6850 -5.6770 Axial C 0.9410 0.9420 Trans D -9.9890 -9.9940 Lateral E 10.3632 10.3759 Lateral F 11.9380 11.9380 GALILS Commanded: 4700. -2450. 3000. -7800. 3300. 3000.
