APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday September 30, 2007 (MJD 54374) ---=== OBSERVING TEAM ===--- Swing: Kaike Pan, Audrey Simmons Night: Dan Oravetz, Howard Brewington ---=== OBSERVING PLAN ===--- SN Science! ---=== OBSERVING SUMMARY ===--- The night was lost to clouds and/or high humidity. ---=== OBSERVING LOG ===--- Afternoon: ---------- Everything is checkout and okay. Spectro monthly checkout out was done (position fibers on CCDS and position spectra in wavelength on CCDS). We took a look at fiducial crosse data took on last friday, and are convinced the data set needs to be re-collected. 23:45Z Opened doors/louvers and turned on fans. Night: ------ 00:45Z Clouds and humidity increased at sunset, so we waited. 02:04Z Closed doors/louvers and turned off fans as humidity became a problem. 02:53Z Opened doors/louvers and turned on fans after humidity decreased. Clouds were still a problem. 03:23Z Closed doors/louvers and turned off fans as humidity became a problem again. 03:54Z Opened doors/louvers and turned on fans after humidity decreased. Clouds were still a problem. 04:30Z Mounted imager as sky began to clear. 04:37Z Did an on-telescope bias (run #7010) and forced filled the spectro dewars while we monitored the cloud cover. 05:10Z Clouds increased again. 08:09Z We got a Watcher error that the PT's LN2 was empty; this was a little confusing since the PT uses a cryoTiger. We, nevertheless, checked the gas pressure of the meter on the backside of the Tigers's compressor. The pressure was 270psi, which was within the normal range. 09:01Z Closed doors/louvers and turned off fans because of high humidity. 11:23Z unmounted imager endNight finished and was happy. 11:30Z Went to bed. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7007 22:03Z 22:20Z 100 O 49.11 53.53 44 ignore 7008 23:53Z 00:13Z 100 O 76.91 81.69 46 ignore 7009 04:37Z 04:38Z 100 O 148.10 148.35 16 ignore 7010 04:40Z 04:56Z 100 O 148.66 152.87 42 bias ---=== 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 46440, plate -9999 ------- 22:19 46440 0.0 bias ----- sequence 46441, plate 2805 ------- 22:34 46441 10.0 flat 22:50 46442 10.0 flat 23:04 46443 10.0 flat 23:08 46444 2.0 arc 23:29 46445 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== 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 22:06Z 60 24 4 317 (NW) 380 - 22:38Z 60 24 0 275 (W) 449 - 23:08Z 60 23 2 304 (NW) 367 - 23:39Z 59 24 3 270 (W) 418 - 00:09Z 57 27 0 7 (N) 684 - 00:42Z 57 33 5 77 (ENE) 646 - 01:35Z 54 47 10 89 (E) 841 - 02:07Z 53 48 13 85 (E) 1003 - 02:39Z 53 47 12 83 (E) 984 - 03:12Z 53 47 13 110 (ESE) 1017 - 03:44Z 53 46 15 116 (ESE) 958 - 04:16Z 54 42 16 119 (ESE) 807 - 04:48Z 53 41 19 127 (SE) 865 - 05:20Z 54 36 21 156 (SSE) 712 - 05:52Z 54 36 17 150 (SSE) 772 - 06:24Z 54 36 16 152 (SSE) 728 - 06:57Z 54 38 17 150 (SSE) 772 - 07:29Z 53 45 17 147 (SSE) 895 - 08:01Z 53 46 16 151 (SSE) 1039 - 08:33Z 52 46 13 166 (SSE) 1049 - 09:05Z 52 48 13 145 (SE) 1154 - 09:41Z 53 48 12 157 (SSE) 1121 - 10:13Z 53 48 12 152 (SSE) 1184 - 10:46Z 53 49 12 141 (SE) 1212 - 11:18Z 52 49 13 145 (SE) 1310 - ---=== TELESCOPE STATUS ===--- 23:45Z Opened louvers, cracked doors, turned on fans. 00:45Z Clouds and humidity was increasing at sunset, so we waited. 02:04Z Closed doors/louvers and turned off fans as humidity became a problem. 02:53Z Opened doors/louvers and turned on fans after humidity decreased. 03:22Z Closed doors/louvers and turned off fans after humidity became a problem again. 04:13Z Opened doors/louvers and turned on fans. 9:10Z Doors/louvers closed; fan off No interlocks bypassed.
