APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday October 22, 2003 (MJD 52935) ---=== OBSERVING TEAM ===--- Night: Dan Long, Pete Newman Support: Craig Loomis ---=== OBSERVING PLAN ===--- Science. ---=== OBSERVING SUMMARY ===--- 1100 frames of imaging. All of strip 82S, 126 <= lambda <= -126 (but with 7 deg of bad seeing) then strip 38S over -49 <= lambda <= -18 all with good seeing. ---=== OBSERVING LOG ===--- Pre-flight checks ----------------- No issues. Spectrographs are in focus. Night ----- Moon down and photometric from sunset (except for a set of persistent aircraft contrails to the far west), so we start with imaging. See imaging sections below for details. During run 4203 at 04:04Z, watcher reported "poolNRGangTrim 2" for all imager dewars. A search of sdsshost procedures shows "poolNRGangTrim is the number of Gangs which have been trimmed which had not been retrieved." The archiver was happily writing data to tape. We cleared the error and it did not return. We have a suspicion what this was: at the start of night, Pete made a small error in starting a doghouse bias drift before issuing a tapeLoad. Immediately after ending that drift, he issued initNight -tapeRelabel, so it is possible that some frames/gangs had not been transfered from the doghouse bias. Otherwise, no problems - a good night! endNight is running, and we will ask the day crew to remove the gangs tapes for shipping. Historical note: this is the first October 22 since 1996 that we have obtained data at APO! Fog, rain, cloud, snow, high winds and broken mirrors have plagued this date in the past (including 1995, but Dan's records get spare before that). And this year is warm: the mean temperature at midnight on October 22 between 1995 and 2002 was 40.7F (4.8C), and tonight it is 51F (10.CF). ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4200 22:50Z 23:02Z 100 O 82.70 85.68 31 ignore doghouse bias 4201 23:14Z 23:23Z 100 O 88.78 91.03 27 ignore doghouse bias 4202 00:14Z 00:34Z 100 O 103.71 108.68 47 bias T-bars free, enclosure 4203 01:14Z 09:19Z 82 S 115.00 -123.49 824 science 4204 09:25Z 12:03Z 38 S -52.59 -12.94 276 science ---=== IMAGING RUN DETAILS ===--- All seeing quality determined by seeingRun unless stated.
