APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday May 23, 2003 (MJD 52783) ---=== OBSERVING TEAM ===--- swing Dan Long night Jurek Krzesinski Howard Brewington ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We opened only for a few hours tonight and got 3 exposures on one plate, but did not get enough S/N on it. There were no problems tonight. ---=== OBSERVING LOG ===--- Afternoon: ========== This afternoon the spectrographs were not refocused. Below are the mean offset values from collimate.

Waiting... 05:58Z still there are lightnings around us, but less clouds. 07:11Z We opened doors and switched fans on - maybe we can open? 07:40Z OPENED. 07:40Z Cart 8 plt 1350 mounted. Stars on slew. Clouds came in the middle of the third exposure and we did not get enough S/N on that plate, that is: the lowest S/N was 13.8 but since other two chips did not get more S/N than 15 (14.7, 14.1), and we did not get smear, we did not declare plate done. 09:54Z There is something wet comming on us from north east, visible on the radar, we decided to move enclosure over the telescope and waited. 10:23Z Closing. endNight finished ok. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 3950 21:43Z 21:49Z 100 O -83.96 -82.44 24 ignore 3951 22:03Z 22:11Z 100 O -78.84 -76.91 27 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 Bias levels and comments r2-L: 544 r2-R: 1491 hot col 1475.5 two fibers cut off at upper right ( low row, high col ) r1-L: 1155 r1-R: 1210 hot col 1152.5- 1153.5 two fibers cut off at upper right b2-L: 1220 b2-R: 1200 no fibers run off chip b1-L: 1262 b1-R: 1017 high col 154.5 no fibers run off chip UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 21069, plate 1360 ------- 21:26 21069 0.0 bias 21:29 21070 0.0 bias 21:32 21071 0.0 bias 21:35 21072 10.0 flat 21:39 21073 2.1 arc 21:41 21074 2.1 arc 21:50 21075 0.0 bias 02:40 21077 0.0 bias ok. ----- sequence 21078, plate 1350 ------- 07:51 21078 10.0 flat 07:54 21079 2.0 arc 08:23 21080 1500.1 target 08:51 21081 1500.1 target 09:16 21082 1354.1 target 09:25 21083 240.0 smear bad (done on thick clouds, zero signal) 09:28 21084 10.0 flat 09:30 21085 2.0 arc ok. ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 07:57Z 8 1350 247.53 0.0057 62.03 0.0027 87.70 -0.0075 1.000130 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL6424 Stays: JL6425 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 07:57Z 8 1350 1.00013 -1283 -115 -200 248 62.1 12.5 21 139 gdr 1.8 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:15Z 76 36 14 231 (SW) 1231 - Partly Cloudy 21:48Z 79 37 10 248 (WSW) 941 - Cloudy, Thunder 22:18Z 74 35 9 256 (WSW) 874 - Mostly Cloudy 22:50Z 64 30 19 158 (SSE) 1211 - Cloudy 02:50Z 54 37 21 111 (ESE) 1014 - 03:22Z 53 37 9 72 (ENE) 986 - 03:55Z 54 36 9 85 (E) 985 - 04:27Z 59 31 0 156 (SSE) 1574 - 04:59Z 61 30 4 269 (W) 1283 - 05:31Z 60 30 1 272 (W) 1175 - 06:03Z 60 31 0 214 (SW) 1191 - 06:36Z 60 30 8 157 (SSE) 1084 - 07:07Z 59 33 11 176 (S) 1361 - 07:39Z 55 34 18 156 (SSE) 1088 - 08:11Z 54 35 19 132 (SE) 1253 - 08:43Z 54 36 21 141 (SE) 1235 - 09:15Z 54 37 20 134 (SE) 1404 - 09:45Z 55 35 17 142 (SE) 1175 - 10:16Z 56 35 17 146 (SE) 1141 - ---=== TELESCOPE STATUS ===--- 07:10Z Fans on doors open, dwars refilled. 07:40Z Telescope opened. 10:30Z Telescope closed.
