APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday February 21, 2004 (MJD 53057) ---=== OBSERVING TEAM ===--- Mike Harvanek Steph Snedden ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The night was lost to clouds and occasional snow flurries. The orange N2 bottle (grade 2) which was replaced today is already down to 1500 psi. The 180 l imager dewar pressure was approximately constant throughout the night at 16.7 psi. ---=== OBSERVING LOG ===--- An adjustment to the spectro collimation was made. See the Problems section for details. Snow delayed building ventilation until 01:50Z. Ventilation stopped at 05:40Z due to dust. Clouds and snow flurries kept us closed all night. The orange bottle (grade 2 N2) in the lower enclosure was replaced today by Norm Blythe. The pressure at 23:30Z was 1700 psi. The pressure at 11:30Z was down to 1500 psi. We may have another leak. The 180 l imager dewar pressure remained around 16.7 psi for the entire night. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4478 23:22Z 23:36Z 100 O -149.05 -145.39 38 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 25245, plate -9999 ------- 23:17 25245 0.0 bias 23:24 25246 0.0 bias ----- sequence 25247, plate 1461 ------- 01:32 25247 2.1 arc test 01:35 25248 2.1 arc test 01:41 25249 10.0 flat test 01:43 25250 2.0 arc test 01:54 25251 10.0 flat test 02:04 25252 2.0 arc test 02:15 25253 2.0 arc test 02:28 25254 2.1 arc test 02:31 25255 2.1 arc test 02:44 25256 2.1 arc test 02:47 25257 2.1 arc test ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: None Stays: None ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:00Z 33 18 16 214 (SW) -9999 - cloudy 23:33Z 31 22 29 246 (WSW) -9999 - snow 00:05Z 30 22 8 266 (W) -9999 - snow 00:37Z 31 21 11 260 (W) -9999 - cloudy 01:10Z 31 19 11 222 (SW) -9999 - cloudy 01:42Z 32 17 17 215 (SW) -9999 - cloudy 02:12Z 33 15 18 205 (SSW) -9999 - cloudy 02:43Z 33 13 22 217 (SW) -9999 - cloudy 03:14Z 34 12 15 199 (SSW) -9999 - cloudy 03:46Z 34 12 20 204 (SSW) -9999 - cloudy 04:19Z 34 13 18 183 (S) -9999 - cloudy 04:51Z 33 15 13 187 (S) -9999 - cloudy 05:23Z 33 15 14 181 (S) -9999 - cloudy 05:55Z 32 16 24 204 (SSW) -9999 - cloudy 06:28Z 32 16 27 223 (SW) -9999 - cloudy 07:00Z 32 16 21 214 (SW) -9999 - cloudy 07:32Z 32 16 19 235 (SW) -9999 - cloudy 08:04Z 32 15 21 217 (SW) -9999 - cloudy 08:36Z 32 16 13 196 (SSW) -9999 - cloudy 09:09Z 32 15 8 258 (WSW) -9999 - cloudy 09:41Z 32 16 9 240 (WSW) -9999 - cloudy 10:13Z 31 16 16 199 (SSW) -9999 - snow 10:45Z 31 19 13 200 (SSW) -9999 - snow 11:18Z 30 20 13 198 (SSW) -9999 - snow ---=== TELESCOPE STATUS ===--- 01:50Z Enclosure doors opened, fans and blowers on, louvers opened. 05:40Z Doors closed, fans and blowers off, louvers closed (dust).
