APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday April 14, 2005 (MJD 53475) ---=== OBSERVING TEAM ===--- Scot Kleinman Atsuko Nitta Mike Harvanek (swing) Visiting: Howard Brewington Jurek Krzesinski Steph Snedden ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Four plates done. Variable/bad seeing prevented imaging. No major problems. ---=== OBSERVING LOG ===--- Afternoon: ---------- During checkout there was an az slip/az windscreen touch (00:33:44Z). Not sure which caused which but both az slip lights were triggered. Based on the temperatures forecast for tonight, no adjustments to the spectro collimation were made. Numbers are in the Problems section. High dust prevented early ventilation. Nothing else to report. Night: ------ Slightly high dust (with a possibly significant pollen component), along with clouds, kept us from ventilating/opening by twilight. Later, nearby bad radar echoes kept us closed. 05:46Z: safe enough to open - start with cart 3 plate 1986. fk5 on the edge. 07:30Z: finished in 3 exposures (3600s) - on to cart 7 plate 1977. GSOTGTF. 08:10Z: finished in one additional exposure. We now have a photometric sky, but our seeing and the DIMM seeing are not imaging-quality. And, besides, the Happy Fun Ball (R) said "Don't press your luck." On to cart 5, plate 2021. GSOTGTF. 09:17Z: finished in 3 exposures (2700s). On to cart 8 plate 1690 (priority 4). Needed an fk5 star (~-10" in RA). 10:51Z: finished in 3 exposures (3600s) in variable seeing. on to cart 9 plate 1574. fk5 star needed, but not easily found. A spiralPattern found it +10" away (not the usual of late -20") in RA. 11:42Z: Not finished in two exposures (2100s)- twilight! We rejoiced for endNight. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5249 23:50Z 00:04Z 100 O -90.12 -86.50 38 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): y QA Procedures Done (y/n): y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 32072, plate -9999 ------- 23:48 32072 0.0 bias ----- sequence 32073, plate 1690 ------- 23:56 32073 10.0 flat collimation check 23:59 32074 2.0 arc collimation check 00:04 32075 2.1 arc collimation check 00:06 32076 2.1 arc collimation check ----- sequence 32077, plate -9999 ------- 00:36 32077 0.0 bias 01:43 32078 0.0 bias ----- sequence 32079, plate 1986 ------- 06:00 32079 10.0 flat 06:03 32080 2.0 arc 06:25 32081 900.1 target 06:49 32082 1200.1 target 07:17 32083 1500.1 target 07:20 32084 10.0 flat 07:23 32085 2.0 arc DONE ----- sequence 32086, plate 1977 ------- 07:37 32086 10.0 flat 07:40 32087 2.0 arc 08:01 32088 900.1 target DONE ----- sequence 32089, plate 2021 ------- 08:11 32089 10.0 flat 08:14 32090 2.0 arc 08:33 32091 900.1 target 08:51 32092 900.2 target 09:09 32093 900.1 target DONE ----- sequence 32094, plate 1690 ------- 09:24 32094 10.0 flat 09:27 32095 2.0 arc 09:46 32096 900.1 target 10:19 32097 1500.1 target 10:43 32098 1200.1 target DONE ----- sequence 32099, plate 1574 ------- 11:24 32099 1200.1 target 11:42 32100 900.1 target 11:45 32101 10.0 flat 11.0 10.3 11.4 10.5 11:48 32102 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 06:12Z 3 1986 203.01 0.0133 81.84 0.0072 25.40 0.0582 1.000410 06:41Z 3 1986 227.93 0.0133 78.15 0.0072 54.70 0.0582 1.000370 07:45Z 7 1977 235.10 0.0092 77.44 0.0044 62.84 0.0152 1.000230 08:19Z 5 2021 244.63 0.0049 66.72 0.0037 81.12 -0.0068 1.000230 09:39Z 8 1690 61.79 -0.0072 80.44 0.0059 236.84 0.0308 1.000290 11:07Z 9 1574 290.34 0.0040 71.75 0.0037 119.43 0.0109 1.000090 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL8466 Stays: JL8467 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 06:11Z 3 1986 1.00041 -4048 -1910 325 203 81.9 8.4 20 142 gdr 1.7 07:45Z 7 1977 1.00023 -2270 -709 50 235 77.5 7.8 13 153 gdr 1.6 08:19Z 5 2021 1.00023 -2270 -693 50 245 66.7 8.1 14 157 gdr 1.4 09:39Z 8 1690 1.00029 -2863 -1303 -50 62 80.4 7.3 8 151 gdr 1.8 11:07Z 9 1574 1.00009 -889 343 -50 290 71.8 8.4 8 148 gdr 1.4 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:34Z 53 28 17 207 (SSW) 2202 - 00:09Z 53 29 9 184 (S) 2141 - 00:42Z 51 30 11 165 (SSE) 2325 - 01:14Z 50 30 19 144 (SE) 2191 - mostly cloudy 01:34Z 50 30 18 148 (SSE) 2431 - 02:06Z 49 31 21 128 (SE) 2240 - 02:38Z 48 31 23 139 (SE) 2208 - 03:10Z 48 31 15 137 (SE) 2111 - 03:43Z 47 31 18 119 (ESE) 2004 - 04:15Z 47 31 17 123 (ESE) 2032 - 04:47Z 46 31 23 126 (SE) 2165 - 05:19Z 46 31 19 121 (ESE) 2200 - 05:50Z 46 32 22 124 (SE) 2293 - 06:21Z 46 32 17 125 (SE) 2185 - 06:51Z 46 31 21 125 (SE) 2171 - 07:22Z 46 31 17 130 (SE) 2067 - 07:53Z 46 31 14 146 (SE) 2148 - 08:24Z 46 31 11 159 (SSE) 2108 - 08:54Z 46 30 11 162 (SSE) 2023 - 09:25Z 44 31 6 150 (SSE) 2061 - 09:58Z 46 31 11 149 (SSE) 1992 - 10:30Z 46 31 10 139 (SE) 2031 - 11:03Z 47 30 8 174 (S) 1914 - 11:35Z 47 30 9 144 (SE) 2007 - 12:06Z 46 29 5 146 (SE) 2035 - ---=== TELESCOPE STATUS ===--- 05:30Z: opened and ventilated ~12:00Z: closed ; fans off - cart 9 mounted ---=== SOFTWARE USED ===--- IOP/SOP: v3_143_1 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: v1_98 SoS: v4_10_7 hoggPT: v1_6_9 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A 0.5780 0.5770 Axial B 0.5910 0.5880 Axial C 0.9480 0.9460 Trans D -8.1990 -8.1960 Lateral E 10.0457 10.0330 Lateral F 11.5951 11.5951 GALILS Commanded: 4300. -1900. 2850. -13300. -7600. -7650.
