APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday March 24, 2004 (MJD 53089) ---=== OBSERVING TEAM ===--- Swing: Pete Newman Night: Howard Brewington, Steph Snedden Support: Craig Loomis (monitoring network traffic) ---=== OBSERVING PLAN ===--- Science. ---=== OBSERVING SUMMARY ===--- Eight plates finished amid pointing inaccuracy and some cloud. A good night, overall! ---=== OBSERVING LOG ===--- Swing shift ----------- See end of the log for spectrographic focus checks. No adjustments were required. Night: ------ Moon plus clouds ==> spectroscopy. Note: tonight's apo_plotbias results are in the problems section. There is also a list of missing science fibers for the engineering crew to compare with their list. Cartridge 7, plate 1779 Needed an FK5 in twilight. Stars were at the edges of the fibers. Science was underway by the end of twilight. This plate was completed with a total exposure time of 2160 s. One spectro guider failure (see problems section). 03:11Z Cartridge 3, plate 1599 Clearing the offsets and adding a 10 asec E offset found the FK5. Finished with a total exposure of 2620 s. 04:32Z Cartridge 5, plate 1455 Needed an FK5 to find the field. Another guider failure (problems section). Finished the plate with a total exposure of 2520 s. 05:35Z Cartridge 8, plate 1623 Needed an FK5 to find the field. Fiber 11 is out of focus relative to the other guide fibers..a known problem, as I recall, but still with us. A guider flat failure during precal (problems section). Clouds thickened during the first exposure, so our efficiency started to drop. Finished the plate with a total exposure of 3000 s. 07:03Z Cartridge 1, plate 1369 Needed a spiral pattern on an FK5 to find the field. Finished the plate with a total exposure time of 2100 s. 08:20Z Cartridge 9, plate 1376 Needed a spiral pattern to find the FK5. Finished the plate with a total exposure time of 1920 s. 09:30Z Cartridge 6, plate 1772 Spiral pattern plus extra searching needed. Offset 20 asec E needed. Finished this plate with a total exposure of 2600 s. We got warnings about scattered light: sdR-r2-00025831.fit: WARNING: Scattered light max = 103 electrons (Warm CCD or twi?) sdR-r2-00025832.fit: WARNING: Scattered light median = 41 electrons (Warm CCD or twi?) sdR-r2-00025832.fit: WARNING: Scattered light max = 259 electrons (Warm CCD or twi?) sdR-r2-00025833.fit: WARNING: Scattered light max = 85 electrons (Warm CCD or twi?) A look at the sky spectra didn't show much difference between r1 and r2, so we are not too worried by these messages. 10:42Z Cartridge 4, plate 1381 Guide stars on goToField! Woo-hoo. Finished this plate with a total exposure of 2520 s. DIMM: At the end of the night, we left Armin's software running, but shut down the VNCviewer. If the DIMM computer reboots itself today, the next step will be to look at the VNC server as the culprit. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4530 23:48Z 00:06Z 100 O -111.05 -106.46 45 ignore doghouse bias ---=== 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 25789, plate -9999 ------- 23:42 25789 0.0 bias 23:53 25790 0.0 bias ----- sequence 25791, plate 1779 ------- 00:08 25791 10.0 flat test 00:12 25792 2.1 arc test 00:15 25793 2.1 arc test 00:25 25794 2.0 arc 00:41 25795 10.0 flat focus checks 00:44 25796 2.0 arc 01:12 25798 0.0 bias ----- sequence 25798, plate 1779 ------- 02:09 25799 10.0 flat 02:11 25800 2.0 arc 02:37 25801 720.1 target 02:52 25802 720.1 target 03:07 25803 720.1 target ----- sequence 25804, plate 1599 ------- 03:24 25804 10.0 flat 03:27 25805 2.0 arc 03:45 25806 900.1 target 04:00 25807 720.1 target 04:20 25808 1000.1 target ----- sequence 25809, plate 1455 ------- 04:36 25809 10.0 flat 04:38 25810 2.0 arc 04:57 25811 900.1 target 05:15 25812 900.1 target 05:30 25813 720.1 target ----- sequence 25814, plate 1623 ------- 05:52 25814 10.0 flat 05:54 25815 2.0 arc 06:24 25816 1200.1 target 06:47 25817 1200.1 target 07:00 25818 600.1 target ----- sequence 25819, plate 1369 ------- 07:31 25819 10.0 flat 07:33 25820 2.0 arc 07:52 25821 900.1 target 08:05 25822 600.1 target 08:18 25823 600.1 target ----- sequence 25824, plate 1376 ------- 08:37 25824 10.0 flat 08:39 25825 2.0 arc 08:54 25826 720.1 target 09:07 25827 600.1 target 09:20 25828 600.1 target ----- sequence 25829, plate 1772 ------- 09:42 25829 10.0 flat 09:44 25830 2.0 arc 09:58 25831 600.1 target 10:21 25832 1200.1 target 10:38 25833 800.1 target ----- sequence 25834, plate 1381 ------- 10:51 25834 10.0 flat 10:53 25835 2.0 arc 11:11 25836 900.1 target 11:29 25837 900.1 target 11:44 25838 720.1 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:30Z 7 0 167.98 -0.0053 73.67 0.0018 -15.38 0.0000 1.000180 03:30Z 3 1599 56.39 0.0042 56.31 0.0010 225.46 -0.0021 1.000390 04:42Z 5 1455 127.01 -0.0010 54.37 0.0027 -81.92 -0.0302 1.000380 05:58Z 8 1623 30.52 0.0064 61.38 0.0013 205.43 -0.0032 1.000270 07:41Z 1 1369 214.18 -0.0078 74.69 0.0067 41.75 0.0004 1.000220 08:44Z 9 1376 206.57 -0.0096 77.29 0.0075 31.40 0.0188 1.000250 09:47Z 6 1772 -60.35 0.0051 59.39 0.0061 130.85 0.0082 1.000070 11:12Z 4 1381 249.68 0.0017 66.25 0.0058 86.32 0.0046 1.000020 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL7357 Stays: JL7358 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 02:30Z 7 0 1.00018 -1778 -221 125 168 73.7 9.2 14 239 - 1.2 03:30Z 3 1599 1.00039 -3850 -1901 125 56 56.3 9.1 12 254 - 1.5 04:42Z 5 1455 1.00038 -3751 -1813 125 127 54.4 9.3 11 237 - 1.8 05:58Z 8 1623 1.00027 -2665 -1033 25 31 61.4 9.5 14 268 - 1.1 07:41Z 1 1369 1.00022 -2171 -674 0 214 74.7 9.0 12 270 - 1.2 08:44Z 9 1376 1.00025 -2468 -922 0 207 77.3 8.9 8 266 - 1.2 09:47Z 6 1772 1.00007 -691 582 0 -60 59.4 9.0 12 278 - 1.4 11:12Z 4 1381 1.00002 -198 1025 50 250 66.3 8.5 12 276 - 1.2 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:58Z 56 29 19 223 (SW) 588 - pcl 23:30Z 54 29 11 264 (W) 655 - " 00:01Z 55 31 14 234 (SW) 694 - " 00:33Z 53 31 13 262 (W) 766 - " 01:04Z 51 28 16 233 (SW) 816 - " 01:14Z 50 28 13 260 (W) 747 - " 01:46Z 49 26 12 261 (W) 738 - " 02:20Z 49 27 15 237 (WSW) 886 - " 02:50Z 49 28 15 234 (SW) 784 - " 03:24Z 48 28 13 240 (WSW) 799 - " 03:56Z 48 26 13 235 (SW) 803 - " 04:28Z 48 24 12 236 (SW) 731 - " 04:59Z 49 23 11 223 (SW) 732 - " 05:32Z 49 23 13 247 (WSW) 669 - " 06:03Z 49 22 15 266 (W) 686 - " 06:33Z 48 24 15 264 (W) 672 - " 07:03Z 48 24 12 268 (W) 776 - " 07:34Z 48 26 11 267 (W) 807 - " 08:06Z 48 26 9 269 (W) 842 - " 08:38Z 48 26 7 267 (W) 796 - " 09:09Z 48 26 8 269 (W) 842 - " 09:45Z 48 26 12 278 (W) 899 - " 10:19Z 47 25 16 272 (W) 906 - mclear 10:52Z 47 25 14 284 (WNW) 898 - " 11:22Z 47 25 10 265 (W) 857 - " 11:56Z 46 25 12 263 (W) 904 - " 12:28Z 46 24 14 271 (W) 912 - " ---=== TELESCOPE STATUS ===--- 00:45Z (approx.)
