APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday November 7, 2008 (MJD 54778) ---=== OBSERVING TEAM ===--- Elena Malanushenko (swing) Howard Brewington (observer) Dmitry Bizyaev (observer) and MARVELS team: Nathan De Lee Jiang Peng ---=== OBSERVING PLAN ===--- Science! 7 Nov 2008 54778.0 0.63 MARVELS until 08:26 (7.4 h), then BOSS/SEGUE (3.6 h) ---=== OBSERVING SUMMARY ===--- Clear photometric quality sky all night long. Exposed Marvels survey plates 3076 (c.9), 3077(c.3), 3075 (c.8), 3082 (c.6). Got good addition of signal to plate 3161 (c.7), SEGUE. In the evening, the cartridge lift did not work properly in "auto" position, it did not push cartridge more than ~100 lbs. Whole night we worked in "manual" position where there was no such problem. Only 3 guide stars found in field B plate 3077 (Marvels survey) cart. 3. ---=== OBSERVING LOG ===--- Afternoon: ========== All systems are checked and they work properly. Spectro collimation is adjusted for 1.5C. 23:30 ventilation Cart 9 is mounted. Lift did not go up completely when I replaced the cartridge 7 to cart 9. I used auto side of controls. Lift went up to 100lb, but not to expected ~1500 weight. Repeat and got the same. Visual inspection and interlock inspection did not show anything unusual. I moved controls to manual side, could lift up to ~1500, but could not unmount the cartridge. (It was my fault, forgot to switch the key.) Tried to use auto side again, could not move lift up to expected weight, and could not move down anymore. Switched to manulal with the Key, unmounted cartridge and replaced it right cart 9 for observations. Leave the controls for manual operation. Night: ====== 00:05Z enclosure off Telescope was fileld and ready at 00:46Z. 00:46Z gotoField with cartridge 9, plate 3076 field B (Marvels survey) fk5 used Marvels calibration with gang-connector in the floor was taken before the LN2 fill was finished, and finished right before going to the field. 00:52Z guide stars found, but on high sky background. Marvels exposure with field B. Marvels calibration 01:53Z gotoField B while calibrating. fk5 used. Calibration is over, go off field, stop, switch gand connector, start again, stars found. 02:16Z Marvels exposure with plate 3076 field A; now it is 50 min exposures. Marvels calibration between the exposured -- 03:08Z cart. 3 plate 3077 field A mounted. GSOGTF Marvers exposures with this field A (2x25 min) GangC moved to the floor 04:18Z Calibration started and gotofield with field B started 04:27Z gotofield again after switching GC to field B Marvels controls its exposure, 1x50 min We found only 3 guide stars in Field B! No more. GC switched to the floor --- 05:32Z cart.8 plate 3075 (Marvels survey) field A mounted, gotoField fk5 used Marvels survey exposure 1x50min Floor calibrations after this 06:30Z GC switched to field B 06:38Z gotoField with field B GSOGTF Marvels survey exposure 1x50 min. Floor calibration -- 07:38Z cart.6 plate 3082 field A mounted (Marvels survey) GSOGTF Marvels survey exposure, 1x50 min GC switched to the floor Strange, the plate has only two bright fibers, no more. I'm pretty sure it was plugged to field A, although there is no way to check it once the gang connector is unplugged. We'll check it tomorrow observing it again. -- 08:35Z cart. 7 plate 3161 mounted (SEGUE) fk5 used We noticed that collimation gets worse and adjusted sp1,sp2 pistons by +2000. 08:54Z precal 09:18Z science 1800 good exposure 09:51Z science 1800 '' 10:24Z midcal 10:32Z science 1800 11:05Z science 1800 11:38Z postcal 11:45Z science 1800 Finally, for this plate we have got a good signal: ------------------------------------- MJD b1 r1 b2 r2 Texp ------------------------------------- 54776 2.2 1.7 2.4 1.0 1800.0 54776 1.9 1.8 2.1 1.0 1501.0 54777 3.7 2.8 3.9 2.0 1801.0 54777 5.2 3.3 6.0 2.0 1800.0 54777 6.5 3.5 8.6 2.9 1800.0 54777 7.5 3.9 11.9 4.9 1800.0 54778 9.6 4.3 9.9 4.5 1801.0 54778 11.9 4.8 13.1 5.2 1800.0 54778 11.0 4.5 12.1 5.4 1801.0 54778 12.1 4.6 13.5 5.4 1800.0 54778 10.2 4.2 10.7 4.8 1800.0 Total: 81.8 39.4 94.2 39.1 19504.0 Total when ALL b,r values > 2.0: 77.7 35.9 89.7 37.1 16203.0 ------------------------------------- --- 12:25Z enclosure on 12:33Z endNight rejoiced ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7795 22:28Z 22:48Z 100 O 93.79 98.60 46 ignore 7796 22:57Z 23:04Z 100 O 101.03 102.79 22 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 56316, plate -9999 ------- 22:28 56316 0.0 bias ----- sequence 56317, plate 3161 ------- 22:46 56317 10.0 flat 22:49 56318 2.0 arc 22:55 56319 3.0 arc 22:57 56320 3.0 arc ----- sequence 56321, plate -9999 ------- 23:24 56321 0.0 bias 23:27 56322 0.0 bias ----- sequence 56323, plate 3161 ------- 23:31 56323 0.0 bias ----- sequence 56324, plate 3161 ------- 08:56 56324 10.0 flat 08:59 56325 2.0 arc 09:13 56326 10.0 flat 09:15 56327 2.0 arc 09:49 56328 1801.0 target 10:22 56329 1800.0 target 10:25 56330 10.0 flat 10:28 56331 2.0 arc 11:04 56332 1801.0 target 11:36 56333 1800.0 target 11:40 56334 10.0 flat 11:42 56335 2.0 arc 12:17 56336 1800.0 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:07Z 9 3076 101.80 -0.0002 50.98 0.0003 255.83 0.0043 1.000100 02:16Z 9 3076 132.50 0.0018 80.93 -0.0020 -52.53 0.0397 0.999910 03:25Z 3 3077 163.46 -0.0006 50.03 -0.0010 -41.54 0.0181 1.000000 04:33Z 3 3077 135.19 0.0003 61.24 -0.0015 -66.09 0.0191 1.000010 05:36Z 8 3075 -50.78 -0.0026 71.91 0.0006 135.95 0.0225 0.999990 07:48Z 6 3082 39.89 0.0045 72.60 0.0002 214.76 0.0216 1.000020 09:32Z 7 3161 118.21 0.0010 63.91 -0.0004 -80.87 0.0051 1.000090 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:07Z 9 3076 1.00010 -986 336 -25 102 51.0 5.8 12 13 -- 1.5" 02:16Z 9 3076 0.99991 888 1863 10 132 80.9 5.8 22 23 -- 1.3" 03:25Z 3 3077 1.00000 1 1181 0 163 50.0 5.7 25 20 -- 1.8" 04:33Z 3 3077 1.00001 -98 1143 75 135 61.2 4.4 21 31 -- 1.2" 05:36Z 8 3075 0.99999 99 1285 75 -51 71.9 3.9 5 51 -- 1.2" 07:48Z 6 3082 1.00002 -196 1049 85 40 72.6 4.4 4 180 -- 1.5" 09:32Z 7 3161 1.00009 -888 443 35 118 63.9 4.0 18 127 -- 1.8" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:22Z 37 2 4 2 (N) 693 - 21:54Z 39 -2 12 26 (NNE) 334 - 22:26Z 41 -5 17 26 (NNE) 337 - 22:58Z 40 -6 22 52 (NE) 252 - clear 23:30Z 42 -5 17 31 (NNE) 137 - '' 00:02Z 42 -7 7 358 (NNW) 132 - '' 00:35Z 42 -7 18 1 (N) 215 - '' 01:09Z 42 -7 14 31 (NNE) 152 - '' 01:43Z 42 -5 19 25 (NNE) 133 - '' 02:13Z 42 -5 24 15 (NNE) 139 - '' 02:43Z 43 -4 21 21 (NNE) 113 - '' 03:13Z 41 -4 24 20 (NNE) 124 - '' 03:44Z 42 -4 23 35 (NE) 100 - '' 04:16Z 40 -6 13 13 (NNE) 257 - '' 04:46Z 40 -5 18 26 (NNE) 221 - '' 05:18Z 39 -7 5 359 (NNW) 159 - '' 05:50Z 39 -7 9 38 (NE) 304 - '' 06:23Z 37 -8 2 96 (E) 144 - '' 06:56Z 37 -7 7 84 (E) 162 - '' 07:28Z 39 -5 4 74 (ENE) 159 - '' 08:01Z 39 -6 8 128 (SE) 141 - '' 08:33Z 40 -5 5 174 (S) 138 - '' 09:05Z 40 -7 12 146 (SE) 89 - '' 09:37Z 39 -6 17 126 (SE) 105 - '' 10:09Z 39 -5 18 135 (SE) 101 - '' 10:41Z 38 5 17 126 (SE) 65 - '' 11:13Z 38 -4 19 142 (SE) 97 - '' 11:47Z 38 -1 17 141 (SE) 92 - '' 12:18Z 38 6 19 131 (SE) 75 - '' ---=== TELESCOPE STATUS ===--- 23:30Z - Began ventilation.
