APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday April 4, 2007 (MJD 54195) ---=== OBSERVING TEAM ===--- Kaike Pan Audrey Simmons Justin Crepp (UF) Suvrath Mahadevan (UF) French Ledger (support by phone) Steph Snedden (support by phone) Connie Rockosi (support by phone) ---=== OBSERVING PLAN ===--- ET Science! ---=== OBSERVING SUMMARY ===--- Mostly clear skies for the night. We had an imager power supply failure, which made us lose about 50 min of sky time. It was replaced with a spare. See log. Observed plates: Cart 6, plate 8016 Cart 9, plate 8017 Cart 2, plate 8018 Cart 3, plate 8024 Cart 5, plate 8025 Cart 1, plate 8026 Cart 8, plate 8021 (2 exposures) Cart 7, plate 8022 ---=== OBSERVING LOG ===--- Night: ----- Checkout went smoothly. Clear skies at opening. 00:30Z Started ventilation with doors and louvers open, fans on. 01:20Z Opened enclosure. 01:32Z Cart 6, plate 8016 mounted. Offsets were used to find guide stars. 50 min exposure. Seeing varied from 1.3-2.5". 03:21Z Cart 9, plate 8017. GSFOGTF. 50 min expousre. 04:24Z Cart 2, plate 8018. GSFOGTF. 50 min exposure. 05:24Z Cart 3, plate 8024. GSFOGTF. 50 min exposure. Seeing varied from 1.3-1.0". 05:35Z watcher complained about imager voltages and CCD temperatures. All of voltages went red. Steph was called, then Connie. Connie suspected the problem was due to a power supple failure, and told us that it should be okay for us to take care of the problem after finishing the ongoing exposure (30 min). After the exposure, we checked and confirmed that one (P3) SDSS camera power supper went bad, then french was called to find spare power supply. Per Frech's and Connie's instructions, we replaced the P3 power supply with a spare. About 50 min was lost. 06:28Z ET mid-night calibration. 07:28Z Cart 5, plate 8035. GSFOGTF. 50 min exposure. 08:30Z Cart 1, plate 8026. GSFOGTF. 50 min exposure. 09:28Z Cart 8, plate 8021. Used offsets to find guide stars. 50 min exposure. 10:25Z Started second 50 min exposure. 11:31Z Cart 7, plate 8022. Used offsets to find guide stars. 50 min exposure. 12:20Z Enclosure on. 12:21Z endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== 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 43992, plate -9999 ------- 00:15 43992 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:21Z 6 8016 -35.81 0.0000 51.33 0.0000 150.52 0.0000 1.000210 03:25Z 9 8017 -47.90 -0.0006 52.90 0.0010 141.20 -0.0131 1.000260 04:26Z 2 8018 243.46 -0.0013 49.07 0.0010 95.39 0.0046 1.000310 05:27Z 3 8024 -49.65 -0.0013 69.14 0.0010 137.56 0.0046 1.000190 07:30Z 5 8025 -41.39 -0.0008 52.76 -0.0005 146.11 -0.0306 1.000110 08:29Z 1 8026 197.82 -0.0008 67.60 -0.0005 25.66 -0.0306 1.000160 09:30Z 8 8021 61.19 0.0017 80.32 0.0008 236.27 -0.0136 1.000140 11:33Z 7 8022 238.83 -0.0038 77.83 0.0027 66.48 0.0448 1.000190 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 00:24Z 1 0 1.00018 -1778 -224 -10 121 30.0 13.1 12 234 - N/A 02:21Z 6 8016 1.00021 -2074 -500 40 -36 51.3 9.7 13 226 - 1.3 03:25Z 9 8017 1.00026 -2568 -974 -20 -48 52.9 8.4 6 195 - 1.5 04:26Z 2 8018 1.00031 -3061 -1370 -20 243 49.1 10.7 10 226 - 1.3 05:27Z 3 8024 1.00019 -1876 -460 -40 -50 69.2 10.5 10 221 - 1.3 07:30Z 5 8025 1.00011 -1086 293 20 -41 52.8 9.1 10 232 - 1.2 08:29Z 1 8026 1.00016 -1580 -152 20 198 67.6 8.4 9 210 - 1.3 09:30Z 8 8021 1.00014 -1383 4 30 61 80.3 9.0 10 229 - 1.3 11:33Z 7 8022 1.00019 -1876 -393 40 239 77.8 7.2 9 186 - 1.3 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:10Z 56 27 17 223 (SW) 795 - Clear 23:42Z 59 26 19 226 (SW) 800 - " 00:14Z 55 26 7 255 (WSW) 787 - " 00:44Z 53 27 9 228 (SW) 785 - " 01:14Z 51 29 9 179 (S) 813 - " 01:45Z 50 25 7 200 (SSW) 896 - " 02:15Z 50 24 8 193 (SSW) 937 - " 02:45Z 48 25 3 98 (E) 897 - " 03:15Z 47 28 4 188 (S) 850 - " 03:47Z 48 26 4 185 (S) 883 - " 04:19Z 51 20 7 225 (SW) 1100 - " 04:50Z 51 18 11 195 (SSW) 1005 - " 05:22Z 51 19 10 192 (SSW) 1005 - " 05:52Z 50 21 9 193 (SSW) 1002 - " 06:24Z 49 23 9 248 (WSW) 990 - " 06:56Z 49 24 9 211 (SSW) 918 - " 07:28Z 48 27 8 228 (SW) 944 - Partly cloudy 07:56Z 47 28 8 231 (SW) 904 - " 08:32Z 47 28 9 199 (SSW) 775 - " 09:04Z 48 26 10 261 (W) 745 - " 09:35Z 48 26 8 217 (SW) 784 - " 10:05Z 46 28 12 206 (SSW) 814 - " 10:37Z 45 32 11 179 (S) 934 - Clearing up 11:09Z 45 32 11 199 (SSW) 875 - " 11:40Z 45 34 10 196 (SSW) 988 - 12:13Z 44 34 10 184 (S) 910 - ---=== TELESCOPE STATUS ===--- 00:30Z - Started ventilation with doors and louvers open, fans are on. 01:20Z - Enclosure off. 12:20Z - Enclosure on, doors and louvers closed, fans off.
