APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday October 23, 2008 (MJD 54763) ---=== OBSERVING TEAM ===--- Elena Malanushenko (swing) Viktor Malanushenko Audrey Simmons ---=== OBSERVING PLAN ===--- Science! 23 Oct 2008 54763.0 0.31 BOSS/SEGUE 10.2 hours ---=== OBSERVING SUMMARY ===--- Clear night with marginal-good seeing (1.3-1.6"). Obtained some twilight spectra. Gathered signal on: Cart 4, plate 3128 Cart 3, plate 3144 (DONE) Cart 6, plate 3135 Cart 7, plate 3314 (No signal values displayed in SOS - this should be corrected by tomorrow) Cart 9, (MARVELS) plate 3043 (DONE) ---=== OBSERVING LOG ===--- Afternoon: ========== All systems are checked and they work properly. Needed to cleanupMurmur. Spectro collimation is adjusted for 3C. Deleted some MJDs from the disk (up to 54706). 23:10 ventilation Night: ======= 00:20Z - Opened enclosure to clear skies. 00:26Z - Sunset. 00:31Z - Precals for twilight spectra test. Telescope pointed at 121,30 during the LN2 fill; cartridge 4 plate 3128 mounted. 00:37Z - Took a 300 sec exposure. Oversaturated exposure. No good. 00:48Z - 300 sec exposure. A bit saturated. Could be good. 00:57Z - 300 sec exposure. Counts a bit low. Could be good. Wind gusts up to 25mph. Seeing ~1.3". Start with spectroscopy. 01:07Z - goToField cart 4, segue plate 3128. GSFOGTF. 01:21Z - Precals. 01:35Z - 25 min exposure. Seeing 1.5" 01:45Z - Twilight ends. 02:04Z - 25 min exposure. 02:36Z - Postcals. This plate is not yet complete. 02:46Z - Mounted cart 3, segue plate 3144. GSFOGTF. 02:52Z - Precals. 02:58Z - 30 min exposure. Seeing 1.4" 03:31Z - 30 min exposure. 04:04Z - Postcals. This plate has accumulated enough signal to be declared DONE. 04:18Z - Mounted cart 6, segue plate 3135. Used fk5 to find field. 04:22Z - Precals. 04:29Z - 30 min exposure. Seeing 1.6". SOS returned a red monster warning, but there are absolutely no lights on that surround the telesope or cartridge bay. We cannot explain this error. 05:02Z - 30 min exposure. Another red monster warning. 05:35Z - Postcals. 05:43Z - 30 min exposure. During the exposure, the guider stopped working. The stars were found almost completely outside of the fibers. This exposure was declared BAD. 06:16Z - 30 min exposure. Seeing 1.1" 06:55Z - Adjusted the collimation +2 degrees, so now both spectrographs are set for ~5C. 06:57Z - Midcals. 07:03Z - 30 min exposure. 07:36Z - 30 min exposure. Seeing 1.2" 08:10Z - Postcals. This plate is not yet done. 08:22Z - Mounted cart 7, segue plate 3114. No guides stars, nor fk5. The altitude fiducial was too large. It was corrected, and then offsets were cleared. The field was found with an fk5. 08:34Z - Precals. 08:41Z - 25 min exposure. Seeing 1.5" 09:05Z - Moonrise. 09:09Z - 25 min exposure. 09:36Z - Midcals. 09:43Z - 25 min exposure. This exposure is not done yet, although SOS is still not reading out signal values. It should be corrected by tomorrow. 10:16Z - Mounted cart 9, marvel's preselection plate 3043 (field A). Altitude fiducial too large again. After correcting it, we found the field with an fk5. 10:31Z - Precals. 10:39Z - 5*20 sec exposures. Seeing 1.4" 10:56Z - Postcals. 11:02Z - goToField plate 3043, field B. GSFOGTF. 11:07Z - Precals. 11:14Z - 5*20 sec exposures. Seeing 1.3" 11:29Z - 5*30 sec exposures. 11:45Z - Postcals. 11:51Z - Twilight begins. 11:54Z - Forgot to run the series of 5*30 sec exposures on field A. Going back to the field. GSFOGTF. 11:58Z - Precals. 12:01Z - 5*30 sec exposures. Seeing 1.3" 12:21Z - Postcals. This plate is declared DONE. 12:40Z - Closed enclosure; stopped ventilating. Mounted cart 4 for tomorrow. 12:41Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7750 21:10Z 21:30Z 100 O 59.37 64.44 45 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): yes QA Procedures Done (y/n): yes UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 55761, plate -9999 ------- 21:04 55761 0.0 bias ----- sequence 55762, plate 3128 ------- 22:06 55762 10.0 flat 22:08 55763 2.0 arc 22:13 55764 3.0 arc 22:16 55765 3.0 arc ----- sequence 55766, plate -9999 ------- 23:29 55766 0.0 bias 23:53 55767 0.0 bias ----- sequence 55767, plate 3128 ------- 00:33 55768 10.0 flat 00:36 55769 2.0 arc 00:44 55770 301.0 target 00:54 55771 300.0 target 01:03 55772 301.0 target 01:23 55773 10.0 flat 01:26 55774 2.0 arc 02:03 55775 1501.0 target 02:36 55776 1801.0 target 02:39 55777 10.0 flat 02:41 55778 2.0 arc ----- sequence 55779, plate 3144 ------- 02:55 55779 10.0 flat 02:57 55780 2.0 arc ----- sequence 55779, plate 3144 ------- 03:31 55781 1802.0 target 04:04 55782 1802.0 target 04:07 55783 10.0 flat 04:09 55784 2.0 arc ----- sequence 55785, plate 3135 ------- 04:25 55785 10.0 flat 04:27 55786 2.0 arc 05:01 55787 1800.0 target 05:34 55788 1800.0 target 05:37 55789 10.0 flat 05:40 55790 2.0 arc 06:15 55791 1800.0 target 06:48 55792 1800.0 target 06:59 55793 10.0 flat 07:02 55794 2.0 arc 07:35 55795 1800.0 target 08:08 55796 1800.0 target 08:11 55797 10.0 flat 08:14 55798 2.0 arc ----- sequence 55799, plate 3114 ------- 08:37 55799 10.0 flat 08:40 55800 2.0 arc 09:08 55801 1500.0 target 09:36 55802 1500.0 target 09:39 55803 10.0 flat 09:41 55804 2.0 arc 10:10 55805 1501.0 target ----- sequence 55806, plate 3043 ------- 10:35 55806 10.0 flat 10:37 55807 2.0 arc 10:41 55808 21.0 target 10:45 55809 20.0 target 10:48 55810 21.0 target 10:52 55811 21.0 target 10:55 55812 21.0 target 10:58 55813 10.0 flat 11:01 55814 2.0 arc 11:10 55815 10.0 flat 11:12 55816 2.0 arc 11:16 55817 21.0 target 11:19 55818 21.0 target 11:23 55819 21.0 target 11:26 55820 21.0 target 11:29 55821 21.0 target 11:32 55822 31.0 target 11:36 55823 31.0 target 11:39 55824 30.0 target 11:43 55825 31.0 target 11:46 55826 31.0 target 11:49 55827 10.0 flat 11:52 55828 2.0 arc 12:01 55829 10.0 flat 12:03 55830 2.0 arc 12:07 55831 31.0 target 12:10 55832 31.0 target 12:14 55833 30.0 target 12:17 55834 31.0 target 12:20 55835 31.0 target 12:23 55836 10.0 flat 12:26 55837 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:18Z 4 3128 66.16 0.0015 53.92 -0.0011 232.29 0.0146 0.999900 03:00Z 3 3144 31.26 0.0027 42.14 0.0018 206.29 0.0508 0.999920 04:31Z 6 3135 59.70 0.0064 76.04 -0.0003 233.22 0.0289 1.000000 08:53Z 7 3114 -64.12 -0.0034 55.60 0.0009 128.82 -0.0031 1.000060 10:38Z 9 3043 23.55 0.0012 60.67 0.0007 199.76 0.0264 1.000220 11:01Z 9 3043 12.13 0.0012 62.14 0.0007 190.26 0.0264 1.000220 11:17Z 9 3043 30.54 0.0015 59.00 0.0009 205.44 0.0274 1.000120 12:09Z 9 3043 -23.57 -0.0007 60.68 0.0011 160.30 0.0203 1.000220 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:18Z 4 3128 0.99990 986 2012 25 66 53.9 5.5 11 356 -
