APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday December 9, 2007 (MJD 54444) ---=== OBSERVING TEAM ===--- Kaike Pan Audrey Simmons ---=== OBSERVING PLAN ===--- SEGUE Science! ---=== OBSERVING SUMMARY ===--- We fought with clouds all night, as well as humidity for the first couple of hours and with radar returns and high wind the latter portion of the night. Nevertheless, we were able to obtain some signal on cartridge 1, plate 2824. ---=== OBSERVING LOG ===--- We wanted to set the spectrograph temperature for ~3C tonight, but we had a hard time adjusting the motors. Moving the motors individually worked, but the spectrographs did not seem to respond to the temperature change (see SOS results). We got it to work after a few tries. Night: ------ 23:16Z - Opened doors and louvers, and turned on fans for ventilation. 00:13Z - Stopped ventilating because of high humidity. We closed doors and louvers and turned the fans off. 02:03Z - Started ventilating again since the humidity went down. However, thicker clouds came in and the wind picked up (about 20mph) from the east. We delayed opening. 03:01Z - Opened enclosure. 03:11Z - Mounted cart 1, seguefaint167 plate 2824. Took postcals to double check collimation. We did not find any stars on goToField, nor did we see an fk5. We applied offsets inside the TCC from a couple nights ago with no luck either. Next, we tried a large spiralPattern (in steps of 20") and finally found the fk5 star. 03:55Z - Precals. 04:02Z - 25 min exposure. Seeing 1.4" 04:30Z - 25 min exposure. 04:57Z - Postcals. Did not finish plate. 05:15Z - Mounted cart 5, chunk171 plate 2878. Used spiral pattern with fk5 to find field (see offest section). 05:23Z - 15 min exposure. Seeing 1.4" Thick clouds came through. This exposure was aborted. We decided to wait and see if the clouds will clear. We sent the telescope to stow position and closed the flat field screens as a precaution. 06:43Z - We put on the enclosure because of nearby radar returns, but stayed ventilating. 07:33Z - Stopped ventilating. It started snowing and the wind became too high. 11:27Z - Called it a night because of nearby radar returns, thick clouds, high wind, and high humidity... 11:35Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7226 22:53Z 23:12Z 100 O 130.78 135.50 44 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 47813, plate -9999 ------- 22:33 47813 0.0 bias 22:37 47814 0.0 bias ----- sequence 47815, plate 2309 ------- 22:46 47815 10.0 flat 22:49 47816 2.0 arc 22:56 47817 3.0 arc 22:59 47818 3.0 arc 23:43 47819 10.0 flat 23:45 47820 2.0 arc 00:11 47821 10.0 flat 00:13 47822 2.0 arc 00:17 47823 3.0 arc 00:20 47824 2.0 arc 00:32 47825 10.0 flat 00:34 47826 2.0 arc ----- sequence 47827, plate 2824 ------- 03:12 47827 10.0 flat 03:14 47828 2.0 arc 03:58 47829 10.0 flat 04:00 47830 2.0 arc 04:29 47831 1501.0 target 04:57 47832 1501.0 target 05:00 47833 10.0 flat 05:03 47834 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 04:03Z 1 2824 -89.51 -0.0256 61.56 0.0004 107.40 0.0000 1.000020 05:23Z 5 2878 -40.85 -0.0133 38.21 0.0007 146.09 -0.0096 1.000100 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 04:03Z 1 2824 1.00002 -198 1135 150 -90 61.5 2.6 24 199 - 1.4 05:23Z 5 2878 1.00010 -988 515 110 -41 38.2 2.2 17 156 - 1.4 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:07Z 40 27 9 189 (S) 467 - Cloudy, humid 22:39Z 38 25 14 192 (SSW) 401 - " 23:10Z 38 25 18 207 (SSW) 465 - " 23:43Z 34 28 15 181 (S) 610 - " 00:14Z 32 29 12 164 (SSE) 644 - " 00:47Z 32 29 19 148 (SSE) 694 - " 01:19Z 32 29 19 168 (SSE) 757 - " 01:51Z 33 27 17 176 (S) 692 - " 02:24Z 33 27 18 166 (SSE) 740 - Clear 02:56Z 34 21 19 184 (S) 510 - " 03:27Z 36 18 21 191 (S) 348 - Cloudy 04:00Z 36 22 20 198 (SSW) 329 - Clear 04:32Z 36 26 23 172 (S) 399 - " 05:03Z 37 25 24 183 (S) 457 - Cloudy 05:35Z 36 27 20 178 (S) 563 - " 06:07Z 36 26 13 216 (SW) 496 - " 06:39Z 36 26 21 174 (S) 470 - " 07:11Z 38 24 14 184 (S) 468 - Cloudy. snowy, windy 07:44Z 37 25 26 192 (SSW) 483 - " 08:16Z 35 26 18 140 (SE) 489 - " 08:48Z 36 27 22 161 (SSE) 477 - Cloudy 09:20Z 36 26 23 178 (S) 536 - " 09:52Z 36 27 20 177 (S) 457 - " 10:25Z 35 28 26 173 (S) 432 - " 10:57Z 34 29 21 147 (SSE) 551 - " 11:29Z 34 30 25 149 (SSE) 731 - ---=== TELESCOPE STATUS ===--- 23:16Z - Began ventilation.
