APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday July 7, 2005 (MJD 53559) ---=== OBSERVING TEAM ===--- Howard Brewington John Barentine ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- ---=== OBSERVING LOG ===--- Afternoon --------- No issues during checkout. Spectro focus looked good so we made no changes. Night ----- Mostly clear at sunset with low clouds off to the northwest, winds light, humidity low. We were open and cooling at 02:20Z, starting with spectro. 03:15Z Cart 2 Plate 1806 (tile 1318, chunk94). We begin with (S/N)^2=12.8 on this plate, so one science exposure ought to finish it. No GSOGTF but an fk5InFiber number 10 found it. Finished in one exposure. 04:06Z Cart 6 Plate 2202 (tile 1586, chunk116). GSOGTF. This plate already has a (S/N)^2 of 6.4 on it, so we imagine two exposures will finish it. After the first exposure read out we began to get clouds; by the start of the second science exposure the clouds were thick enough to pause, then abort, the science exposure. Returns nearby on radar began to scare us, so we closed up at 04:50Z. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5435 23:11Z 23:32Z 100 O -16.90 -11.80 43 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 33315, plate -9999 ------- 23:14 33315 0.0 bias 23:19 33316 0.0 bias ----- sequence 33317, plate 1806 ------- 23:26 33317 10.0 flat 23:28 33318 2.0 arc 23:35 33319 10.0 flat ----- sequence 33320, plate -9999 ------- 23:58 33320 0.0 bias ----- sequence 33320, plate 1806 ------- 03:31 33321 10.0 flat 03:33 33322 2.0 arc 03:54 33323 900.1 target ----- sequence 33324, plate 2202 ------- 04:12 33324 10.0 flat 04:14 33325 2.0 arc 04:33 33326 900.1 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 03:39Z 2 0 -52.45 0.0020 55.80 0.0058 137.42 0.0083 1.000070 ---=== 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 ------------------------------------------------------------------------------ 03:39Z 2 0 1.00007 -691 351 -240 -53 55.8 20.9 5 273 -- 1.1 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:06Z 75 23 14 263 (W) 587 - 23:37Z 77 24 11 262 (W) 508 - 00:09Z 74 21 12 268 (W) 513 - 00:42Z 75 21 17 273 (W) 473 - 01:14Z 72 21 6 318 (NW) 460 - 01:46Z 71 21 4 301 (WNW) 514 - 02:18Z 70 20 4 349 (NNW) 536 - 03:15Z 70 20 4 277 (W) 600 - 03:46Z 69 21 3 264 (W) 596 - 04:19Z 68 21 1 238 (WSW) 599 - 04:51Z 69 21 3 205 (SSW) 596 - 05:24Z 67 23 9 346 (NNW) 677 - 05:56Z 67 27 7 104 (ESE) 610 - ---=== TELESCOPE STATUS ===--- 02:20Z Fans and blowers on, louvers open, enclosure off 04:50Z Enclosure on, doors half-open, fans left on ---=== SOFTWARE USED ===--- IOP/SOP: v3_149_0 Watcher: v2_30_0 MCP: v5_26_0 TPM: tpm_v2_47_0 AstroDa: v14_47 TCC: TCC 2.7.2.1 August 6 2004 sdssProcedures: v2_02 SoS: v4_10_7 hoggPT: v1_6_9 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A 0.5500 0.5770 Axial B 0.5930 0.5880 Axial C 0.9850 0.9460 Trans D -8.1860 -8.1960 Lateral E 10.0457 10.0330 Lateral F 11.5951 11.5951 GALILS Commanded: 4300. -1900. 2850. -13300. -7600. -7650.
