APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday November 14, 2004 (MJD 53324) ---=== OBSERVING TEAM ===--- Jurek Krzesinski Steph Snedden Mike Harvanek (swing) Visitor: Douglas Tucker (FNAL) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Nothing done, we never opened. During afternoon checkout Mike reported: Something weird is going on with collimator motor C on sp1. It went from reading -7875 on 53322 to 0 on 53323 to -7875 on 53324 (today) without having been moved. See the log for more. ---=== OBSERVING LOG ===--- Afternoon: ---------- Spectro collimation was adjusted. Details are in the Problems section. Something weird is going on with collimator motor C on sp1. It went from reading -7875 on 53322 to 0 on 53323 to -7875 on 53324 (today) without having been moved. It doesn't appear to have actually moved because the collimation was okay during this period yet it doesn't seem to have been a reset either because it went back to what it was reading before it read 0. Maybe it was just a communications problem? Windscreen touches during checkout: altitude (Windscreen touched in altitude: UP (2004-11-14 23:46:19Z sdssmcp): 2004-11-14 23:46:36Z) and altitude (Windscreen touched in altitude: UP (2004-11-15 00:20:50Z sdssmcp): 2004-11-15 00:21:08Z) It's getting to the point where windscreen touches occur almost every time the telescope is released from its stow position. Snow is drifting into the upper enclosure under and around the east door. Nothing was found in the rest of the building (both upper and lower enclosure). Nothing else to report. Night: ------ Due to bad weather we never opened. Nothing was done. endNight run on cloudy tapes. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4965 23:19Z 23:52Z 100 O 113.48 121.58 68 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 29387, plate -9999 ------- 23:12 29387 0.0 bias ----- sequence 29388, plate 1925 ------- 23:52 29388 10.0 flat collimation 23:55 29389 2.0 arc collimation 23:58 29390 2.1 arc collimation 00:00 29391 2.1 arc collimation 00:12 29392 2.1 arc collimation 00:15 29393 2.1 arc collimation ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL none Stays: JL none ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:41Z 28 25 19 84 (E) 43 - 23:13Z 26 24 21 98 (E) 744 - 23:45Z 27 26 22 110 (ESE) 277 - 00:18Z 30 28 21 120 (ESE) 190 - clouds, snow 00:50Z 26 25 20 83 (E) 102 - clouds, snow 01:22Z 27 26 25 77 (ENE) 414 - clouds, snow 01:50Z 28 27 22 102 (ESE) 3221 - 02:22Z 28 27 19 91 (E) 2535 - 02:55Z 29 28 26 111 (ESE) 1252 - 03:31Z 30 29 25 124 (SE) 444 - 04:03Z 29 29 23 110 (ESE) 418 - 04:39Z 31 30 22 107 (ESE) 262 - 05:12Z 31 31 25 117 (ESE) 165 - 05:48Z 31 30 20 107 (ESE) 2800 - 06:20Z 31 31 20 117 (ESE) 11554 - 06:52Z 30 30 25 111 (ESE) 3519 - 07:24Z 30 30 27 123 (ESE) 4008 - 07:57Z 32 32 21 120 (ESE) 16564 - 08:29Z 32 32 30 123 (ESE) 8583 - 09:01Z 32 32 21 144 (SE) 28589 - 09:33Z 33 32 26 147 (SSE) 49425 - 10:05Z 33 32 25 141 (SE) 22600 - 10:42Z 32 32 20 121 (ESE) 12775 - ---=== TELESCOPE STATUS ===--- We never opened. ---=== SOFTWARE USED ===--- IOP/SOP: v3_142_0 Watcher: v2_29_0 MCP: v5_25_0 TPM: tpm_v2_43_0 AstroDa: v14_47 TCC: TCC 2.7.2.1 August 6 2004 sdssProcedures: v1_95 SoS: v4_10_7 hoggPT: v1_6_9 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A 0.5400 0.5250 Axial B 0.5990 0.6020 Axial C 0.9280 0.9050 Trans D -8.6040 -8.6120 Lateral E 10.0330 10.0203 Lateral F 11.6205 11.5951 GALILS Commanded: 4800. -2150. 2600. -6900. -7850. -7900.
