APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday January 18, 2008 (MJD 54484) ---=== OBSERVING TEAM ===--- Viktor Malanushenko (swing) Audrey Simmons (observer) Dan Oravetz (observer) ---=== OBSERVING PLAN ===--- Bright-time Science! ---=== OBSERVING SUMMARY ===--- Acquired signal on cartridge 2, 2851. Acquired enough signal on cartridge 4, 1249 to declare it done and we updated the database with the signal, but did not declare it done because we were told it would probably be re-plugged. Finished cartridge 3, 2656. Finished cartridge 5, 2604. Finished cartridge 6, 2605. The west rail stop button (just to the south of the dimm) was flickering almost all night long. We didn't notice it at opening, but we noticed it during the first cartridge change. The stop button can be seeing flickering on the 2.5m webcam. The manipulator arm functioned just fine with the interlocks logic ON and despite the cold temperatures (as low as -11.2C). ---=== OBSERVING LOG ===--- Afternoon: ---------- All equipment checked and working properly. Like two last days, there is a big difference between temperature inside both sp1 and sp2 (+0.4C and -1.6C) and air temperature (-5.7C). By that reason, I adjusted collimation on -2.3C lower as curremt moment (see in 'problem' section). Spectro collimation set for -4.0C for spectro or -8.0C for the air temperature. Bias level of left side of CCD33 is off again (it is uniformly > 16500 counts). 23:30Z - Began ventilation. Doors and louvers opened, fans on. Cartridge 2 is mounted. Night: ------ 00:25Z - Enclosure off. 00:28Z - Sunset. Cartridge 2, plate 2851, segue169 ********************************* 00:56Z - gotoField. The sky brightness was too bright to find guide stars, so we used an fk5 and found it in guide fiber 10 without applying any additional offsets. 01:28Z - Pre-Calibs. 01:34Z - 900-second exposure. 01:49Z - End twilight. 01:52Z - 900-second exposure. 02:09Z - 900-second exposure. 02:28Z - Mid-Calibs. 02:36Z - 1200-second exposure. Seeing: 1.5" - 2.3" fwhm. SOS warned of bad sky residuals, scattered light, a whopping fiber, and a red monster (exposure 49143). 03:10Z - We noticed the west rail stop button flickering again. Cartridge 4, plate 1249, orion61 ******************************** 03:10Z - gotoField. Guide stars found on gotoField. There was a large scale change (0.03 percent scale) for this old plate. 03:19Z - Pre-Calibs. 03:26Z - 900-second exposure. Guider on, no offset. 03:48Z - 900-second exposure. Guider off, +9 offset in A. 04:08Z - 900-second exposure. Guider on, no offset. 04:26Z - 900-second exposure. Guider off, -9 offset in A. 04:44Z - 900-second exposure. Guider on, no offset. 05:02Z - Mid-Calibs. 05:10Z - 900-second exposure. Guider off, +9 offset in A. 05:29Z - 900-second exposure. Guider on, no offset. 05:47Z - 900-second exposure. Guider off, -9 offset in A. 06:07Z - 900-second exposure. Guider on, no offset. 06:25Z - 900-second exposure. Guider off, +9 offset in A. 06:44Z - 900-second exposure. Guider on, no offset. 07:02Z - 900-second exposure. Guider off, -9 offset in A. 07:20Z - Post-Calibs. Seeing: 1.3" - 2.0" fwhm. Enough signal has been acquired on this plate to declare it done, but we did not declare it done because we were told that it would probably be re-plugged since the signal was obtained under very moony conditions and therefore there would be not point in removing it from the database. Cartridge 3, plate 2656, chunk153 ********************************* 07:30Z - gotoField. Guide stars found on gotoField. 07:39Z - Pre-Calibs. 07:46Z - 1500-second exposure. 08:14Z - 1500-second exposure. 08:42Z - 1500-second exposure. 09:10Z - 1500-second exposure. 09:38Z - 1800-second exposure. 10:11Z - Post-Calibs. Seeing: 1.3" - 2.1" fwhm. This plate is DONE. Cartridge 5, plate 2604, chunk153 ********************************* 10:22Z - gotoField. Guide stars found on gotoField. 10:28Z - Pre-Calibs. 10:34Z - 1800-second exposure. Seeing: 1.2" - 1.9" fwhm. This plate is DONE. Cartridge 6, plate 2605, chunk153 ********************************* 11:12Z - gotoField. Guide stars found on gotoField. 11:17Z - Pre-Calibs. 11:24Z - 1500-second exposure. 11:52Z - 1500-second exposure. 12:19Z - 1200-second exposure. Seeing: 1.2" - 1.7" fwhm. This plate is DONE. SOS recommended post-cal's after the last exposure, but it was too late. 12:50Z - Enclosure on, doors and louvers closed, fans off. 13:00Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7292 22:06Z 22:26Z 100 O 158.45 163.38 47 ignore CCD33 left side high ---=== 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 49127, plate -9999 ------- 22:01 49127 0.0 bias ----- sequence 49128, plate 2604 ------- 22:27 49128 10.0 flat 22:29 49129 2.0 arc 22:33 49130 3.0 arc 22:36 49131 3.0 arc 23:19 49132 3.0 arc 23:22 49133 3.0 arc ----- sequence 49134, plate -9999 ------- 23:46 49134 0.0 bias 23:51 49135 0.0 bias ----- sequence 49136, plate 2851 ------- 2.8 2.9 14.9 3.8 01:28 49136 10.0 flat 01:31 49137 2.0 arc 01:51 49138 900.0 target 02:09 49139 901.0 target 02:27 49140 900.0 target 02:30 49141 10.0 flat 02:32 49142 2.0 arc 02:59 49143 1200.0 target 03:02 49144 10.0 flat 03:05 49145 2.0 arc ----- sequence 49146, plate 1249 ------- 22.0 23.9 03:22 49146 10.0 flat 03:24 49147 2.0 arc 03:43 49148 901.0 target 04:06 49149 901.0 target 04:25 49150 900.0 target 04:43 49151 900.0 target 05:02 49152 901.0 target 05:05 49153 10.0 flat 05:08 49154 2.0 arc 05:27 49155 901.0 target 05:46 49156 900.0 target 06:04 49157 900.0 target 06:24 49158 901.0 target 06:42 49159 901.0 target 07:01 49160 901.0 target 07:19 49161 900.0 target 07:22 49162 10.0 flat 07:25 49163 2.0 arc ----- sequence 49164, plate 2656 ------- 16.0 23.8 16.0 20.6 07:42 49164 10.0 flat 07:44 49165 2.0 arc 08:13 49166 1500.0 target 08:41 49167 1500.0 target 09:09 49168 1500.0 target 09:37 49169 1500.0 target 10:10 49170 1801.0 target 10:13 49171 10.0 flat 10:16 49172 2.0 arc ----- sequence 49173, plate 2604 ------- 20.0 15.3 19.0 16.3 10:30 49173 10.0 flat 10:33 49174 2.0 arc 11:06 49175 1800.0 target ----- sequence 49176, plate 2605 ------- 32.6 24.8 37.2 23.0 11:19 49176 10.0 flat 11:22 49177 2.0 arc 11:51 49178 1501.0 target 12:19 49179 1500.0 target 12:42 49180 1201.0 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:36Z 2 2851 -10.87 0.0033 56.78 0.0003 170.88 0.0277 0.999960 03:27Z 4 1249 44.68 0.0045 47.83 0.0005 216.28 0.0377 1.000160 06:44Z 4 1249 -35.78 0.0048 51.58 0.0005 150.59 0.0377 1.000040 07:47Z 3 2656 94.58 0.0037 43.51 -0.0007 247.52 0.0302 1.000070 09:16Z 3 2656 81.66 0.0065 62.11 -0.0026 246.53 0.0328 0.999980 10:34Z 5 2604 64.29 0.0036 60.44 -0.0019 232.32 0.0219 0.999890 11:30Z 6 2605 45.23 0.0097 68.69 -0.0013 218.54 0.0279 0.999860 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:36Z 2 2851 0.99996 395 1863 375 -11 56.8 -7.7 6 0 ---- 1.7" 03:27Z 4 1249 1.00016 -1580 131 250 45 47.8 -8.9 3 323 ---- 1.9" 06:44Z 4 1249 1.00004 -395 1149 300 -36 51.6 -10.0 17 6 ---- 1.5" 07:47Z 3 2656 1.00007 -691 906 275 95 43.5 -10.4 20 2 ---- 2.1" 09:16Z 3 2656 0.99998 198 1611 300 82 62.1 -11.1 12 24 ---- 1.3" 10:34Z 5 2604 0.99989 1086 2276 225 64 60.5 -10.2 14 14 ---- 1.3" 11:30Z 6 2605 0.99986 1383 2503 225 45 68.7 -9.7 11 4 ---- 1.2" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:22Z 23 1 3 336 (NNW) 495 -
