APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday January 3, 2008 (MJD 54469) ---=== OBSERVING TEAM ===--- Viktor Malanushenko (days) Stephanie Snedden (observer) Dmitry Bizyaev (observer) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We got some signal with cartridge 9 plate 2865 cartridge 1 plate 2866 and two under-threshold exposures with cartridge 2 plate 1631 (low signal in clouds), all in gradually thickened cirrus clouds. Finally clouds became very thick and we closed. According to request from Steve Kent, we ask to unplug 2872 from cartridge 6 and plug plate 2608 (moirning chunk). ---=== OBSERVING LOG ===--- Afternoon: ---------- All equipment are checked and work properly. Spectro collimation set for 0C. Ventilation is started at 23:40Z. Cartridge 6 is mounted. Nigt: ----- 00:20Z opened dome Cart. 9 plate 2865 (seguefaint) is on the telescope Offsets cleared, then applied those from previous night. GSOGTF. 01:16Z precal Ups, flat and arc indicate not perfect collimation for both sp1,sp2. Moved pistons -3000 on both 01:33Z one more precal; it's getting worse. Piston moved back and 3000 more 01:49Z and now the good precal 01:53Z science 1500 cirrus clouds everywhere 02:28Z science 1500 clouds postcal 02:50Z Cart 1 plate 2866 mounted GSOGTF 03:05Z precal 03:12Z science 1500 cirrus clouds 03:40Z science 1500 cirrus clouds postcal Cart. 2 plate 1631 mounted 04:24Z science 1500 --> 1800 clouds getting worse 04:58Z postcal 05:13Z science 1800 dense clouds 06:57Z enclosure is put back on because of radar returns and dangerous clouds coming. 11:45Z very dense clouds, no hope to open, less than an hour to twilight. We decided to stow the telescope and stop ventillation. 11:52Z endNight rejoiced ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7268 21:40Z 22:06Z 100 O 137.08 143.59 57 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- 7268 46 4 0 0.000 0.000 0.000 0.000 -0.00000 0 0 ---=== 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 48598, plate -9999 ------- 21:38 48598 0.0 bias ----- sequence 48599, plate 2872 ------- 22:07 48599 10.0 flat 22:10 48600 2.0 arc 22:15 48601 3.0 arc 22:17 48602 2.0 arc ----- sequence 48603, plate -9999 ------- 23:07 48603 0.0 bias 23:11 48604 0.0 bias ----- sequence 48605, plate 2865 ------- 01:19 48605 10.0 flat 01:21 48606 2.0 arc 01:35 48607 10.0 flat 01:37 48608 2.0 arc 01:46 48609 10.0 flat 01:48 48610 2.0 arc 02:20 48611 1500.0 target 02:48 48612 1500.0 target 02:51 48613 10.0 flat 02:54 48614 2.0 arc ----- sequence 48615, plate 2866 ------- 03:08 48615 10.0 flat 03:10 48616 2.0 arc 03:39 48617 1500.0 target 04:07 48618 1501.0 target 04:10 48619 10.0 flat 04:12 48620 2.0 arc ----- sequence 48621, plate 1631 ------- 04:56 48621 1801.0 target 05:00 48622 10.0 flat 05:02 48623 2.0 arc 05:44 48624 1801.0 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:58Z 9 2865 -2.24 0.0049 47.85 0.0020 178.10 0.0301 1.000120 03:19Z 1 2866 -29.42 0.0072 53.57 0.0031 155.60 0.0170 1.000190 04:30Z 2 1631 -15.06 0.0042 49.66 0.0028 167.31 0.0120 1.000110 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 23:26Z 9 0 1.00000 0 1231 0 121 30.1 3.3 6 262 01:58Z 9 2865 1.00012 -1185 387 180 -2 47.8 1.0 10 234 -- 1.7" 03:18Z 1 2866 1.00019 -1876 -203 180 -29 53.6 1.7 8 246 -- 2.3 04:30Z 2 1631 1.00011 -1086 383 100 -15 49.7 1.4 17 257 -- 1.4" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 20:51Z 40 19 10 212 (SSW) 1750 - clouds 21:23Z 42 20 10 226 (SW) 2274 - '' 21:55Z 41 18 10 240 (WSW) 1809 - '' 22:26Z 42 20 9 272 (W) 1904 - '' 22:59Z 39 20 6 264 (W) 1662 - '' 23:51Z 36 20 6 259 (W) 1576 - '' 00:23Z 36 20 7 264 (W) 1111 - '' 00:55Z 35 20 12 250 (WSW) 1463 - '' 01:26Z 35 21 9 234 (SW) 1502 - '' 01:56Z 33 20 10 249 (WSW) 1643 - '' 02:28Z 34 18 9 236 (SW) 1624 - '' 03:01Z 34 13 13 253 (WSW) 1125 - '' 03:31Z 35 12 16 267 (W) 942 - '' 04:03Z 35 11 12 262 (W) 825 - '' 04:36Z 35 11 14 264 (W) 555 - '' 05:06Z 35 10 20 256 (WSW) 572 - '' 05:37Z 34 11 15 267 (W) 823 - '' 06:07Z 34 11 12 266 (W) 736 - '' 06:37Z 35 9 13 274 (W) 577 - '' 07:09Z 35 8 17 281 (W) 619 - '' 07:42Z 35 7 14 267 (W) 644 - '' 08:14Z 34 11 22 263 (W) 670 - '' 08:46Z 34 13 13 277 (W) 937 - '' 09:18Z 33 15 23 273 (W) 1025 - '' 09:50Z 35 13 20 283 (WNW) 1083 - '' 10:23Z 35 14 8 278 (W) 808 - '' 10:55Z 36 18 9 267 (W) 884 - '' 11:27Z 35 15 17 282 (WNW) 905 - '' 11:59Z 36 17 18 273 (W) 1022 - ---=== TELESCOPE STATUS ===--- 23:40Z - Began ventilation.
