APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday September 23, 2001 (MJD 52176) ---=== OBSERVING TEAM ===--- swing: Mike Harvanek night: Jurek Krzesinski & Atsuko Nitta Kleinman ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- WARNING: We don't have any plates for the beginnings of nights!!!! Afternoon telescope & DA checkout ok. We find stars in fibers all the time, with offset 15''. DONE: cart 2 plt 636 mounted done with 3 exposures (int times: 900,900,1200 sec) NOT done: cart 8 plt 641 , 6 exposures taken but S/N was very low (int times: 1200,900,900,900,1200,1200 sec.) 00:40 The humidity rised up to closing condition, and the telescope was closed to the end of the night. No problems occured tonight. ---=== OBSERVING LOG ===--- Afternoon telescope & DA checkout ok. 18:45 Telescope opened with car 2 plt 636 mounted. 19:55 GotoField - stars found with A:15'' offset Full step errors - ignored. 3.5m observers got seeing 1.3'' when ours was around 2'' - we decided to repeat guiderFocus... Didn't help, the focus stays as before (100 at temp 9 C). S/N on the first exposure was aroun 3, so we decided that we need only two exposures to declare this plate done. Unfortunately during instChange, when SoS finaly reported S/N we found out that the second exposure S/N is below 2! We went back to the same field hoping that with the next exposure the plate will be done. And indeed it was done with exposure time 1200 sec. 21:50 cart 8 plt 641 mounted and gotoFiled. Stars found with the previous offsets. There are scattered clouds in the sky, but the seeing is better (1.8'') at least for a while. We've tried to make this plate done with 6 exposures but we couldn't. So we gave up. But smearing was done (clear sky during exposure and no clouds visible on the cloud camera). 00:40 The humidity rose up to closing condition! 00:53 Telescope closed, with cart 9 plt 679 mounted. 04:45 Since the humidity stabilized at the high level we called endNight. No problems occured tonight. ---=== IMAGING RUN SUMMARY ===--- Run Stripe Flavor Lambda Last Begin End Frame Comments ------------------------------------------------------------------ ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot --------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields nGood rowMean rowSig colMean colSig rot --------------------------------------------------------------- ---=== SPECTROSCOPY DATA SUMMARY ===--- UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 11015, plate -9999 ------- 20:23 11015 0.0 bias {{}} 23:39 11016 0.0 bias {{}} 00:27 11017 0.0 bias {{}} ----- sequence 11018, plate 636 ------- 02:08 11018 10.0 flat pre-flat ----- sequence 11015, plate -9999 ------- 20:23 11015 0.0 bias {{}} 23:39 11016 0.0 bias {{}} 00:27 11017 0.0 bias {{}} ----- sequence 11018, plate 636 ------- 02:08 11018 10.0 flat pre-flat 02:11 11019 2.0 arc pre-arc 02:29 11020 900.0 target science 02:50 11021 900.0 target science 02:56 11022 240.0 smear {{Smear Pattern}} 03:13 11023 10.0 flat pre-flat 03:15 11024 2.0 arc pre-arc 03:39 11025 1201.0 target science ----- sequence 11026, plate 641 ------- 04:06 11026 10.0 flat science pre-flat 04:08 11027 2.0 arc pre-arc 04:34 11028 1201.0 target science 04:52 11029 900.0 target science 05:09 11030 900.0 target science 05:27 11031 900.0 target science 05:50 11032 1202.0 target science 06:18 11033 1201.0 target science 06:25 11034 240.0 smear {{Smear Pattern}} 06:28 11035 10.0 flat post-flat 06:30 11036 2.0 arc post-arc Plate 636 was observed in sequence(s) 11018 11018 for a total of 3001 seconds Plate 636 was observed in sequence(s) 11018 11018 for a total of 3001 seconds Plate 641 was observed in sequence(s) 11026 for a total of 6304 seconds ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument getclock Az Alt Rot Scale ------------------------------------------------------------------------------ 20:21 2 636 1001298069 0.005198 -0.000789 0.004821 0.999890 22:21 8 641 1001305276 0.007231 -0.000346 0.018073 0.999750 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL4485 Stays: JL4486 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 20:21 2 636 0.99989 1085 2168 75 31 46.0 8.8 23 72 - 2.0 22:22 8 641 0.99975 2468 3125 -100 0 49.7 9.0 15 86 - 2.2 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 17:36 55 32 13 70 (ENE) 252 - 18:06 53 33 15 80 (E) 223 - 18:37 51 34 21 68 (ENE) 204 - 19:07 50 35 15 75 (ENE) 166 - 19:37 49 37 28 73 (ENE) 230 - 20:08 48 40 24 65 (ENE) 269 - 20:39 48 40 23 76 (ENE) 296 - 21:09 48 39 19 81 (E) 282 - 21:39 48 40 20 73 (ENE) 303 - 22:11 48 39 13 86 (E) 275 - 22:43 48 39 19 68 (ENE) 281 - 23:14 47 39 17 75 (ENE) 243 - 23:48 47 39 7 85 (E) 288 - 00:20 46 38 2 95 (E) 280 - 00:52 45 41 13 74 (ENE) 317 - 01:24 45 43 3 99 (E) 331 - 01:56 45 43 8 71 (ENE) 414 - 02:29 44 42 10 89 (E) 352 - 03:01 44 41 17 67 (ENE) 270 - 03:33 44 41 18 60 (ENE) 261 - 04:05 44 41 22 60 (ENE) 267 - 04:37 43 41 20 61 (ENE) 205 - 05:10 45 40 15 50 (NE) 259 - ---=== TELESCOPE STATUS ===--- 18:45 Telescope opened with car 2 plt 636 mounted. 00:53 closed - because of the humidity, cart 9 plt 679 mounted.
