APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday March 29, 2007 (MJD 54189) ---=== OBSERVING TEAM ===--- Kaike Pan Dan Oravetz Justin Crepp (UF) Suvrath Mahadevan (UF) ---=== OBSERVING PLAN ===--- ET Science! ---=== OBSERVING SUMMARY ===--- 5 exposures on 5 ET plates: E8016 (50-minute template), E8017 (50-minute template), E8018 (50-minute template), E8025 (50-minute data), E8026 (50-minute data). First half of the night was clear and then we battled clouds. No telescope problems tonight...it must have just been upset the last couple of nights in response to Mike's leaving. ---=== OBSERVING LOG ===--- Afternoon: --------- Afternoon checkout went smoothly. No problems to report. 12:40Z - Began ventilation. Doors and louvers open, fans on. Night: ----- 01:25Z - Enclosure off. Opened to clear skies. 02:15Z - Cartridge 6, plate E8016. Needed an FK5 to acquire the field. One 50-minute exposure (template). Seeing: 1.3" - 1.9". 03:23Z - Cartridge 9, plate E8017. Guide stars on the gotoField. One 50-minute exposure (template). Seeing: 1.2" - 1.5". 04:30Z - Cartridge 2, plate E8018. Needed an FK5 to acquire the field. One 50-minute exposure (template). Seeing: 1.6" - 2.5". 05:38Z - Cartridge 5, plate E8025. Guide stars on the gotoField. 06:00Z - Stopped the exposure to check and clean the fibers and check that the iodine cell position was correct and not blocking light - flux was too low. The low flux seemed to be due to the iodine cell position. This was fixed and we started again and the flux was okay. One 50-minute exposure (data). Seeing: 1.9" - 2.5". Note: Every time we go to field, we receive the following error regarding guide fiber saturation for each guide fiber (we show this for fiber 2 as an example): Fiber 2 row diff: -5.820 col diff: 10.800 {mean 3670.5} {meanErr -1} {pixels 2458} {retVal 0} Fiber 2 may be saturated, counts: 3551.5 The complete listing for all fibers (tmp.log) is detailed under the Problems section. 07:16Z - Clouds. 08:06Z - Cartridge 1, plate E8026. Needed an FK5 to acquire the field. One 50-minute exposure (data). Seeing: 1.6" - 2.2". 09:16Z - Clouds. Cartridge 8, plate E8021 mounted. Did not start an exposure because of clouds. 09:34Z - Enclosure on for threatening clouds. West door open halfway and east door open entirely for ventilation. 10:57Z - Doors and louvers closed, fans off. 11:08Z - 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): yes QA Procedures Done (y/n): N/A UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 43925, plate -9999 ------- 00:25 43925 0.0 bias 00:30 43926 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:15Z 6 8016 -24.54 0.0003 54.49 -0.0001 159.54 -0.0078 1.000060 03:27Z 9 8017 -40.42 0.0003 56.05 -0.0001 146.80 -0.0078 1.000080 04:42Z 2 8018 243.64 -0.0025 50.47 -0.0010 94.32 0.0114 1.000140 05:56Z 5 8025 11.94 -0.0010 59.50 -0.0012 189.96 -0.0151 1.000030 08:14Z 1 8026 182.55 -0.0016 69.08 -0.0034 3.56 -0.0065 0.999950 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 02:15Z 6 8016 1.00006 -593 857 180 -25 54.5 -0.3 1 99 ---- 1.3" 03:27Z 9 8017 1.00008 -790 659 150 -40 56.1 -0.5 4 104 ---- 1.4" 04:42Z 2 8018 1.00014 -1383 125 90 244 50.5 0.8 11 141 ---- 1.6" 05:56Z 5 8025 1.00003 -296 1078 170 12 59.5 -0.9 12 80 ---- 1.9" 08:13Z 1 8026 0.99995 494 1632 90 182 69.1 0.3 10 136 ---- 2.2" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 00:26Z 34 0 3 305 (NW) 661 - Clear 00:58Z 32 0 0 265 (W) 686 - Clear 01:30Z 31 2 2 4 (N) 707 - Clear 02:01Z 31 1 1 6 (N) 677 - Clear 02:32Z 31 0 1 130 (SE) 701 - Clear 03:03Z 30 0 8 83 (E) 725 - Clear 03:33Z 31 -2 5 103 (ESE) 737 - Clear 04:03Z 31 -6 6 105 (ESE) 734 - Clear 04:33Z 32 -12 7 117 (ESE) 820 - Clear 05:04Z 35 -11 0 232 (SW) 800 - Clear 05:35Z 31 -12 9 82 (E) 822 - Clear 06:06Z 29 -2 13 79 (E) 781 - Clear 06:37Z 29 4 17 78 (ENE) 736 - Light clouds 07:08Z 28 6 19 81 (E) 792 - Clouds 07:38Z 29 6 10 93 (E) 798 - Clouds 08:09Z 32 3 4 152 (SSE) 825 - Clouds 08:39Z 33 2 15 152 (SSE) 879 - Mostly cloudy 09:09Z 33 2 15 158 (SSE) 923 - Mostly cloudy 09:40Z 33 2 14 155 (SSE) 1079 - Clouds 10:11Z 32 4 11 112 (ESE) 1116 - Clouds 10:42Z 32 5 11 110 (ESE) 1257 - Clouds ---=== TELESCOPE STATUS ===--- 12:40Z - Began ventilation.
