APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday April 25, 2006 (MJD 53851) ---=== OBSERVING TEAM ===--- Days: Howard Brewington Observers: Elena Malanushenko Dan Long Shannon Watters (training) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Tonight was a pretty good night. We finished 5 plates 2480, 2023, 1798, 2094, and 1817. Certainly a better haul than last night. Dust counts averaged a little over 3000 all night and we collected about 32k dust-hours. Humidity was at times a bit higher than previous nights (15%-45%) so a check/snowing? of the primary is in order. We also noticed upon closing that the grade 5 nitrogen pressure is at 500 PSI. ---=== OBSERVING LOG ===--- Afternoon: ---------- Except for the noise bars in the astro/photo monitors, I found no problems during the afternoon checkout. Spectro collimation was checked but not adjusted; it's set to ~+8-degrees C. See Problem Section for the spectro focus numbers. Night: ---------- 02:23Z Cartridge 5 2480 Survey 7.2 5.9 7.5 5.6 Guide stars on slew. 12.6 11.6 12.5 12.3 53849 --------------------- 19.8 17.5 20.0 17.9 Done There are a fair amount of high clouds around. Seeing is about 1.5 - 1.7 arcseconds. We shall see if we have better luck tonight getting that last exposure than we did last night. The first attempt at an exposure near the end of twilight was aborted due to very low efficiencies of 10% or so. 03:30Z Clouds thin enough to warrant another exposure attempt. Nope. 1's on that exposure - 38827 declared bad 03:58Z Trying again. This time efficiency is staying over 50%. Got it that time. 04:26Z postCalib 04:33Z instChange 04:37Z Cartridge 7 2023 Survey 18.4 17.6 22.3 16.1 Done Needed FK5 Clouds slow setup. 04:50Z preCalib 04:56Z First science 38833 Part way through second exposure, seeing worsens to over 2". Done in three. Clouds retreat, leaving skies mostly clear. 05:56Z instChange 06:00Z Cartridge 2 1798 Survey 18.8 13.1 20.7 13.2 Needed FK5 4.4 2.7 5.0 3.2 ------------------- 23.2 15.8 25.7 16.4 Done 06:13Z preCalib 06:19Z First Science 38838 Done in three exposures when combined with last night's data. Dust levels went from 3000 to 8000 for about 15 minutes or so before dropping back to 4000. 07:26Z instChange 07:31Z Cartridge 8 2094 Survey 26.0 13.8 25.6 24.8 Done Guide stars on slew. 07:37Z preCalib 07:43Z First Science 38845 Done in three. r1 was quite a bit lower than all the rest. 08:47Z instChange 08:52Z Cartridge 9 1817 Survey 20.8 20.2 22.1 18.1 Done Guide stars on slew. 08:59Z preCalib 09:15Z First science 09:45Z Seeing goes over 2.5 arcseconds Done in three. Taking extra exposure anyway since there is not enough time to start another plate. 11:10Z Closing 11:44Z endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6112 23:28Z 23:55Z 100 O -85.05 -78.24 56 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 38819, plate -9999 ------- 23:28 38819 0.0 bias ----- sequence 38820, plate 2077 ------- 23:57 38820 10.0 flat 23:59 38821 2.0 arc 00:08 38822 2.1 arc 00:10 38823 2.1 arc ----- sequence 38824, plate -9999 ------- 01:08 38824 0.0 bias ----- sequence 38825, plate 2480 ------- 7.2 5.9 7.5 5.6 12.6 11.6 12.5 12.3 53849 02:50 38825 10.0 flat --------------------- 02:53 38826 2.0 arc 19.8 17.5 20.0 17.9 Done 03:57 38827 1500.1 target 04:24 38828 1500.1 target 04:27 38829 10.0 flat 04:30 38830 2.0 arc ----- sequence 38831, plate 2023 ------- 18.4 17.6 22.3 16.1 Done 04:52 38831 10.0 flat 04:54 38832 2.0 arc 05:18 38833 1200.1 target 05:36 38834 900.1 target 05:54 38835 900.1 target ----- sequence 38836, plate 1798 ------- 18.8 13.1 20.7 13.2 06:14 38836 10.0 flat 4.4 2.7 5.0 3.2 06:17 38837 2.0 arc ------------------- 06:36 38838 900.1 target 23.2 15.8 25.7 16.4 Done 06:54 38839 900.1 target 07:18 38840 1300.1 target 07:21 38841 10.0 flat 07:24 38842 2.0 arc ----- sequence 38843, plate 2094 ------- 26.0 13.8 25.6 24.8 Done 07:38 38843 10.0 flat 07:41 38844 2.0 arc 08:05 38845 1200.1 target 08:23 38846 900.2 target 08:46 38847 1200.1 target ----- sequence 38848, plate 1817 ------- 20.8 20.2 22.1 18.1 Done 09:00 38848 10.0 flat 09:02 38849 2.0 arc 09:37 38850 1200.1 target 09:59 38851 1200.1 target 10:32 38852 1800.1 target 10:55 38853 1200.2 target 10:58 38854 10.0 flat 11:01 38855 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 03:01Z 5 2480 25.23 -0.0031 71.72 0.0015 201.79 -0.0038 1.000170 05:08Z 7 2023 105.96 0.0039 77.84 0.0034 -82.22 0.0219 1.000230 06:24Z 2 1798 -11.33 -0.0053 66.47 0.0016 170.26 0.0208 0.999980 07:45Z 8 2094 273.98 -0.0028 73.61 0.0012 103.85 0.0020 1.000130 09:19Z 9 1817 -40.33 -0.0016 58.52 0.0019 146.61 -0.0054 1.000020 ---=== 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 ------------------------------------------------------------------------------ 03:01Z 5 2480 1.00017 -1679 -161 100 25 71.7 6.9 19 149 - 1.6 05:08Z 7 2023 1.00023 -2271 -860 -100 106 77.8 8.4 12 182 - 1.4 06:24Z 2 1798 0.99998 198 1201 -100 -11 66.5 8.2 19 174 - 2.1 07:45Z 8 2094 1.00013 -1284 -7 -70 274 73.6 8.1 18 185 - 1.3 09:19Z 9 1817 1.00002 -198 967 -25 -40 58.5 6.5 17 158 - 1.8 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:24Z 56 12 4 216 (SW) 2650 - Mostly Clear 22:56Z 57 14 21 201 (SSW) 2586 - Mostly Clear 23:26Z 56 12 15 228 (SW) 2858 - Mostly Clear 23:57Z 56 14 18 196 (SSW) 2862 - Partly Cloudy 00:27Z 50 11 11 187 (S) 2986 - Partly Cloudy 01:00Z 50 7 11 181 (S) 3381 - Partly Cloudy 01:32Z 48 10 9 180 (S) 3225 1.6k Partly Cloudy 02:13Z 46 13 17 157 (SSE) 2793 3.0k Partly Cloudy 02:43Z 45 17 18 140 (SE) 2553 4.3k Partly Cloudy 03:13Z 44 18 17 149 (SSE) 2335 5.4k Partly Cloudy 03:45Z 44 16 12 149 (SSE) 2872 6.9k Partly Cloudy 04:18Z 47 6 16 180 (S) 3235 8.5k Partly Cloudy 04:49Z 48 5 14 178 (S) 3334 10.2k Partly Cloudy 05:20Z 47 3 9 186 (S) 3090 11.7k Partly Cloudy 05:50Z 43 10 9 168 (SSE) 2915 13.2k Mostly Clear 06:21Z 45 8 14 171 (S) 3121 14.7k Mostly Clear 06:52Z 46 11 17 174 (S) 5637 17.6k Clear 07:23Z 47 17 19 172 (S) 4327 19.7k Clear 07:53Z 46 18 15 182 (S) 3529 21.5k Clear 08:24Z 46 18 16 173 (S) 3444 23.2k Mostly Clear 08:55Z 43 18 14 169 (S) 3116 24.8k Clear 09:27Z 43 19 11 170 (S) 3025 26.3k Clear 09:57Z 41 21 10 119 (ESE) 3272 27.9k Clear 10:27Z 41 21 11 139 (SE) 3586 29.7k Clear 10:59Z 40 22 15 142 (SE) 3595 31.5k Clear 11:30Z 40 20 2 97 (E) 3487 32.4k Clear ---=== TELESCOPE STATUS ===--- 01:00Z Doors Open, Fans On, Louvers Open 01:57Z Enclousure Open 11:20Z Enclosure Closed, Louvers Closed, Fans Off.
