APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday April 24, 2006 (MJD 53850) ---=== OBSERVING TEAM ===--- Days: Howard Brewington Observers: Dan Long, Elena Malanushenko Shannon Watters, Sloanie-In-Training(TM) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The weather was cloudy for all night. We worked with 4 plates, but obtained 2 good exposures only. One exposure finished plate 1718 (cart.1) and another collected useful signal 2.7 on plate 1798 (cart.2). Watcher complained about excessive Front-Back M1 T Difference. ---=== OBSERVING LOG ===--- Afternoon: ---------- Found a few problems during the afternoon checkout. I had to reboot photo-two again today because id-5 was unhappy again. As a few days ago, the monitor for id-5 was dark and without a normal display during a goDrift -bias. We still have the vertical noise bars in the the astro/photo monitors. The spectro collimation was checked and adjusted to ~+8-degrees. The final collimation numbers were posted in the Problem Section. Night: ---------- Opened telescope 1:35Z Cartridge 5, plate 2480, chunk Previous signal 11.5 T=8.6C, dust 3800, wind 20 mph, humidity 15.5, clouds Found Stars on GTF. Focus=0, efficiency is 30-60% 3:00Z Precalibration 3:07, 3:39, 4:11, 4:44, 5:17Z - DoNextScience Exposure from 1500 to 1800, paused for clouds several times. All exposures have been declared as bad because of low signal. "Continue" Cartridge 2, plate 1798, chunk. T=8.6C, dust 3000, wind 22 mph, humidity 15.3, clouds. Found Stars on GTF. Focus=-50, efficiency is 14-50% 5:45 Precalibration. 5:53 (abort), 7:44 (good), 8:16 DoNextScience, 1800 sec exposures. The plate was expired. 8:49Z PostCalibration.

Found Stars on GTF. Focus=-50, efficiency is 30-80% 9:07 Precalibration. 9:12 DoNextScience, 1500 9:40 DoNextScience, 1200 - aborted as we obtained the sufficient signal "Done" Cartridge 9, plate 1817, chunk T=7.8C, dust 2800, wind 16 mph, humidity 15.2, clear. Found Stars on GTF. Focus=-50, efficiency is 30-60% 9:59 Precalibration. 10:04 (aborted), 10:35 (bad) DoNextScience, 1500 "Continue" We have watcher complain that one sensor on M1 mirror has 7C less than others. We think this is not real. The message is: "m1 temp (Excessive Front-Back Difference (Right Half):Excessive Front-Back Difference (Upper Half): 2006-04-25 10:37:52Z )" EndNight is completed. 11:30 Closed telescope. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6110 23:23Z 23:29Z 100 O -87.08 -85.70 23 ignore 6111 23:34Z 23:54Z 100 O -84.49 -79.33 49 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): yes QA Procedures Done (y/n): yes UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 38793, plate -9999 ------- 23:16 38793 0.0 bias ----- sequence 38794, plate 2077 ------- 23:44 38794 10.0 flat 23:46 38795 2.0 arc 23:55 38796 2.1 arc 23:58 38797 2.1 arc 00:13 38798 2.1 arc 00:16 38799 2.1 arc ----- sequence 38800, plate -9999 ------- 01:24 38800 0.0 bias ----- sequence 38801, plate 2480 ------- 03:03 38801 10.0 flat 03:05 38802 2.0 arc 03:38 38803 1500.1 target 04:11 38804 1800.1 target 04:43 38805 1800.1 target 05:16 38806 1800.2 target ----- sequence 38807, plate 1798 ------- 05:47 38807 10.0 flat 05:50 38808 2.0 arc 08:16 38809 1800.1 target 08:48 38810 1800.1 target 08:51 38811 10.0 flat 08:53 38812 2.0 arc ----- sequence 38813, plate 1718 ------- 09:09 38813 10.0 flat 09:11 38814 2.0 arc 09:39 38815 1500.1 target ----- sequence 38816, plate 1817 ------- 10:01 38816 10.0 flat 10:04 38817 2.0 arc 11:07 38818 1500.1 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 04:06Z 5 2480 -22.97 -0.0001 71.99 0.0030 159.94 -0.0039 1.000110 05:56Z 2 1798 8.12 -0.0016 66.65 0.0030 186.83 0.0258 1.000050 09:08Z 1 1718 -39.62 -0.0010 63.36 0.0034 146.73 -0.0161 1.000160 10:07Z 9 1817 -55.18 -0.0018 51.69 0.0014 135.77 -0.0113 1.000060 ---=== 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 ------------------------------------------------------------------------------ 04:06Z 5 2480 1.00011 -1086 229 0 -23 72.0 8.0 13 290 -- 1.3 05:57Z 2 1798 1.00005 -494 779 50 8 66.7 8.7 14 286 -- 1.6 09:08Z 1 1718 1.00016 -1580 -213 -50 -40 63.3 8.3 14 318 -- 1.3 10:06Z 9 1817 1.00006 -593 634 -50 -55 51.7 7.8 10 311 -- 1.3 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:13Z 52 8 30 241 (WSW) 4185 - clouds 21:45Z 51 6 18 241 (WSW) 3851 - 22:17Z 54 9 17 206 (SSW) 3908 - 22:49Z 57 10 13 289 (WNW) 3943 - 23:22Z 54 8 17 214 (SW) 3580 - 23:54Z 51 7 22 232 (SW) 4134 - 00:25Z 52 8 24 248 (WSW) 3978 - 01:02Z 51 7 13 257 (WSW) 3643 - 01:32Z 49 4 16 264 (W) 3696 - 02:35Z 47 2 10 265 (W) 3765 - 03:05Z 46 2 14 273 (W) 3656 - 03:37Z 46 1 9 298 (WNW) 3553 - 04:07Z 46 1 12 301 (WNW) 3435 - 04:38Z 46 2 15 296 (WNW) 3066 - 05:08Z 47 2 16 275 (W) 3006 - 05:39Z 47 2 9 289 (WNW) 3084 - 06:11Z 46 2 12 293 (WNW) 3026 - 06:42Z 47 1 14 299 (WNW) 2853 - 07:12Z 46 1 8 307 (NW) 2856 - 07:42Z 47 2 9 328 (NNW) 2832 - 08:12Z 46 2 17 334 (NNW) 2780 - 08:44Z 46 2 14 308 (NW) 2894 - 09:15Z 46 1 8 318 (NW) 2784 - 09:46Z 46 1 11 298 (WNW) 2784 - 10:16Z 46 1 12 310 (NW) 2771 - 10:48Z 45 1 12 310 (NW) 3050 - 11:20Z 45 1 11 315 (NW) 3209 - ---=== TELESCOPE STATUS ===--- 00:55Z Doors and louvers opened, fans on. 01:51Z Enclosure off. 11:30Z Enclosure on, fans off, louvers and doors closed Telescope is parked at 121,30 with Cart 9 (Plate 1817) mounted No interlocks bypassed Spectro autofill reconnected Dewar weights at 11:35Z Imager: 205lbs 20 psi Spectro: 160lbs __ psi ---=== SOFTWARE USED ===--- IOP/SOP: v4_21_0 Watcher: v2_34_0 MCP: v6_3_1 TPM: tpm_v3_3_0 AstroDa: v15_11_1 TCC: TCC 2.7.2.1 August 6 2004 sdssProcedures: v2_11 SoS: v5_1_0 hoggPT: v1_6_9 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A -5.8540 -5.8440 Axial B -5.6740 -5.6770 Axial C 0.9410 0.9420 Trans D -10.0010 -9.9940 Lateral E 10.3759 10.3759 Lateral F 11.9507 11.9380 GALILS Commanded: 4700. -2450. 3000. -7800. 3300. 3000.
