APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday January 1, 2005 (MJD 53372) ---=== OBSERVING TEAM ===--- swing: Jurek Krzesinski Night: Steph Snedden, Howard Brewington ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds. ---=== OBSERVING LOG ===--- Afternoon checkout: ------------------- DA problem - rimfire error on id1, id3 - the drives were cleaned, tapes replaced The odd thing is, that the replaced tapes were fine for DAs for the last 3 days. M1 was homed and relaxed because the lateral E axis has drifted away of nominal values. Homing and relaxing did not bring E axis into spec. Nominal values were reset to the new E axis position. Sp2 needed refocusing (mechPiston -3438). Night: ------ Thick clouds kept us closed all night. We kept the ventilation on and doors open, but weather never let us open. Precipitation threatened toward the end of the night, so we closed the doors to the enclosure at 10:30Z. endNight -nothingHappenedTonight finished. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5093 22:05Z 22:07Z 100 O 142.06 142.75 18 ignore 5094 22:25Z 22:29Z 100 O 147.20 148.05 20 ignore 5095 22:53Z 23:10Z 100 O 154.21 158.35 42 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):n QA Procedures Done (y/n):n UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 30156, plate -9999 ------- 22:06 30156 0.0 bias ----- sequence 30157, plate 2085 ------- 22:11 30157 0.0 bias ----- sequence 30158, plate -9999 ------- 22:19 30158 0.0 bias ----- sequence 30159, plate -9999 ------- 22:30 30159 0.0 bias 22:33 30160 0.0 bias ----- sequence 30161, plate 2085 ------- 22:57 30161 0.0 bias 23:01 30162 10.0 flat 23:05 30163 2.0 arc focus 23:10 30164 2.1 arc " 23:12 30165 2.1 arc " 23:25 30166 2.1 arc " 23:27 30167 2.1 arc " ----- sequence 30168, plate -9999 ------- 23:42 30168 0.0 bias ----- sequence 30169, plate 2085 ------- 23:44 30169 0.0 bias ---=== 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: JL N/A Stays: JL N/A ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 23:23Z 6 0 1.00000 0 1257 0 121 30.0 3.7 14 248 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:01Z 42 11 20 254 (WSW) 1 - cloudy 22:33Z 41 9 12 250 (WSW) 1 - " 23:05Z 39 11 17 264 (W) 2 - " 23:36Z 38 14 3 255 (WSW) 0 - " 00:18Z 38 7 1 120 (ESE) 0 - " 00:50Z 38 6 7 254 (WSW) 0 - " 01:20Z 36 12 6 251 (WSW) 0 - " 01:51Z 36 16 7 204 (SSW) 0 - " 02:21Z 35 21 7 206 (SSW) 0 - " 02:51Z 35 24 6 182 (S) 0 - " 03:21Z 35 18 10 231 (SW) 0 - " 03:51Z 36 17 9 229 (SW) 2 - " 04:21Z 37 19 10 251 (WSW) 0 - " 04:52Z 38 13 9 263 (W) 1 - " 05:22Z 39 13 15 257 (WSW) 2 - " 05:52Z 39 12 13 269 (W) 0 - " 06:22Z 39 10 15 248 (WSW) 0 - " 06:53Z 39 14 10 265 (W) 0 - " 07:23Z 37 18 6 268 (W) 2 - " 07:55Z 39 14 7 236 (SW) 0 - " 08:28Z 38 15 11 235 (SW) 1 - " 09:01Z 38 15 8 245 (WSW) 0 - " 09:32Z 37 15 13 256 (WSW) 0 - " 10:04Z 38 11 7 251 (WSW) 0 - " 10:37Z 38 12 20 264 (W) 3 - " ---=== TELESCOPE STATUS ===--- 23:40Z Doors opened, fans on. 10:43Z Doors closed.
