APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday April 20, 2007 (MJD 54211) ---=== OBSERVING TEAM ===--- Steph Snedden Howard Brewington Elena Malanushenko (day) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Most of the night was lost because of clouds. Plate 2690 declared done. There was a small problem while dismounting Cart 07; see log. ---=== OBSERVING LOG ===--- Afternoon: --------- The telescope has been checked and prepared for observations. All systems are functioning properly. The collimation is set for 7C. It was no necessary to move the collimation pistons. I 00:40Z - Began ventilation. Doors and louvers open, fans on. Cart 7, plate 2690 is mounted. Night: ------- 02:13Z Cart 07, plate 2690 (segue 161). An Fk5 star was used to find the field in bright twilight. Plate was declared done with four exposures. 02:44 44421 10.0 flat 02:46 44422 2.0 arc 03:11 44423 1201.0 target 03:29 44424 902.0 target 03:52 44425 1201.0 target 04:17 44426 1202.0 target 04:20 44427 10.0 flat 04:22 44428 2.0 arc 04:32Z Cart 01, plate 2610 (chunk153). Found guide stars with goToField, and completed one exposure. However, clouds became a problem, and the exposure was declared bad. 04:38 44429 10.0 flat 04:40 44430 2.0 arc 05:09 44431 1501.0 target While mounting Cart 01, I had a problem dismounting Cart 07, i.e., one of the latches did not unlatch. So, I relatched the cart's latches and tried again. This time, I was able to unlatch Cart 07. French was there at this time and observed the problem. 05:30Z Enclosure on because of clouds. 10:33Z Doors and louvers closed; fans off Misc Watcher messages are posted in the Problems Section. endNight finished and was happy. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6797 21:57Z 22:18Z 100 O -112.86 -107.61 49 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): y QA Procedures Done (y/n): y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 44407, plate -9999 ------- 22:21 44407 0.0 bias ----- sequence 44408, plate 2145 ------- 22:27 44408 10.0 flat 22:30 44409 2.0 arc 22:39 44410 0.0 bias 22:49 44411 3.0 arc 22:52 44412 3.0 arc ----- sequence 44413, plate 2690 ------- 00:16 44413 10.0 flat 00:18 44414 2.0 arc 00:21 44415 2.0 arc 00:24 44416 3.0 arc 00:32 44417 2.0 arc 00:34 44418 3.0 arc 00:59 44419 0.0 bias ----- sequence 44420, plate 2690 ------- 02:44 44421 10.0 flat 02:46 44422 2.0 arc 03:11 44423 1201.0 target 03:29 44424 902.0 target 03:52 44425 1201.0 target 04:17 44426 1202.0 target 04:20 44427 10.0 flat 04:22 44428 2.0 arc ----- sequence 44429, plate 2610 ------- 04:38 44429 10.0 flat 04:40 44430 2.0 arc 05:09 44431 1501.0 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:33Z 7 2690 30.90 -0.0002 35.04 0.0007 206.67 -0.0112 1.000030 05:11Z 1 2610 13.53 0.0031 76.82 0.0032 192.01 0.0148 1.000230 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 02:33Z 7 2690 1.00003 -296 916 -75 31 35.1 10.7 20 196 gdr 1.4 05:12Z 1 2610 1.00023 -2271 -808 -50 13 76.8 9.3 10 237 gdr 1.2 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 20:47Z 56 15 25 233 (SW) 1906 - 21:19Z 58 18 13 223 (SW) 1801 - 21:51Z 58 15 26 212 (SSW) 1745 - 22:22Z 58 15 11 228 (SW) 1763 - 22:53Z 57 13 32 211 (SSW) 1977 - 23:23Z 54 12 30 197 (SSW) 1843 - 23:53Z 56 12 24 214 (SW) 1766 - 00:24Z 53 9 22 205 (SSW) 1676 - 00:55Z 52 11 20 203 (SSW) 1820 - 01:22Z 50 10 17 196 (SSW) 1738 - 01:52Z 51 7 17 183 (S) 1860 - 02:23Z 51 5 20 198 (SSW) 1799 - 02:53Z 51 5 16 192 (SSW) 1757 - 03:23Z 51 5 17 202 (SSW) 1584 - 03:53Z 51 5 17 222 (SW) 1695 - 04:23Z 48 6 11 235 (SW) 1632 - 04:53Z 48 5 8 247 (WSW) 1620 - 05:24Z 48 6 12 224 (SW) 1648 - 05:54Z 48 6 8 221 (SW) 1574 - 06:26Z 48 7 12 207 (SSW) 1486 - 06:58Z 48 7 15 212 (SSW) 1509 - 07:30Z 47 6 13 218 (SW) 1284 - 08:02Z 47 5 14 187 (S) 1315 - 08:34Z 46 7 18 202 (SSW) 1068 - 09:06Z 45 7 16 219 (SW) 1207 - 09:39Z 44 8 14 201 (SSW) 1347 - 10:11Z 44 8 21 215 (SW) 1364 - ---=== TELESCOPE STATUS ===--- 00:40Z Began ventilation.
