APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday September 11, 2001 (MJD 52164) ---=== OBSERVING TEAM ===--- Dan Long Steph Snedden Mike Harvanek (swing) Eric Neilsen Bill Boroski Scot Kleinman ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Slight delay in opening due to clouds. Finished plate 634 before humidity forced us to close. Remained closed the rest of the night due to humidity and/or clouds. ---=== OBSERVING LOG ===--- 18:20 Fans on, Doors open 20:10 Open after slight cloud delay 20:30 On sky Cart 2 Plate 634: Stars in fibers after slew using last night's offsets. 20:36: On pre-calibs after grabbing instruments it failed to connect to ports 3 and 4 on the goStare. Ports were logged out and instruments re-grabbed. All was OK after that. 22:10 Closed due to humidity ( fans off ) A/C turned on in conjunction with duct heaters. 02:30 Trade humidity for clouds 04:40 Gave up. A/C and heaters returned to nominal conditions. 04:40 Got PT temperature alarm. Power cycled CryoTiger. Cold head began cooling again. ---=== IMAGING RUN SUMMARY ===--- Run Stripe Flavor Lambda Last Begin End Frame Comments ------------------------------------------------------------------ 2549 100 O ignore 36.08 41.21 48 ---=== 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 23:31 10894 0.0 bias {{}} ----- sequence 10895, plate 634 ------- 15.3 21.6 16.0 18.7 23:40 10895 0.0 bias {{}} 02:22 10896 0.0 bias {{}} 02:47 10897 10.0 flat pre-flat 02:50 10898 2.0 arc pre-arc 03:19 10899 900.0 target science 03:36 10900 901.0 target science 03:59 10901 1201.0 target science 04:06 10902 240.0 smear {{Smear Pattern}} 04:09 10903 10.0 flat post-flat 04:12 10904 2.0 arc post-arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- getclock Axis position and calibration offset Scale Time Ct Plate time Az El Rot Factor 21:03 2 634 1000263789 27.17 .0043 47.74 -.0011 202.63 .0119 0.999820 ---=== TELESCOPE OFFSETS AND SCALE II ===--- sidereal time Plate Telescope Tele - Plate " Time Ct Plate deg RA Dec RA Dec RA Dec 21:03 2 634 290 309.8841 -5.8496 309.8872 -5.8494 11.2 0.7 ---=== DATA TAPE SUMMARY ===--- Goes: JL4375 Stays: JL4376 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 21:02 2 634 0.99982 1776 2611 -50 28 47.4 12.3 18 126 - 1.6 21:32 2 634 0.99982 1776 2653 0 18 49.8 11.8 20 126 - 2.2 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 16:43 56 47 5 93 (E) 292 - Cloudy 17:15 57 47 4 132 (SE) 172 - Cloudy 17:47 57 47 3 125 (SE) 160 - Cloudy 18:19 57 45 11 154 (SSE) 213 - Mostly Cloudy 18:51 57 44 13 144 (SE) 305 - Mostly Cloudy 19:24 56 45 11 128 (SE) 325 - Partly Cloudy 19:56 55 46 17 124 (SE) 244 - Partly Cloudy 20:28 54 46 15 125 (SE) 210 - Mostly Clear 20:58 54 46 18 125 (SE) 204 - Mostly Clear 21:28 53 47 21 126 (SE) 211 - Mostly Clear 22:01 52 48 15 122 (ESE) 206 - Partly Cloudy 22:32 52 48 18 128 (SE) 222 - Partly Cloudy 23:02 52 49 18 125 (SE) 181 - Mostly Clear 23:32 51 49 13 115 (ESE) 198 - Mostly Clear 00:03 51 48 8 104 (ESE) 223 - Clear 00:33 51 49 8 118 (ESE) 191 - Clear 01:03 51 48 7 105 (ESE) 153 - Mostly Clear 01:33 52 47 1 111 (ESE) 200 - Mostly Clear 02:03 55 44 0 249 (WSW) 189 - Mostly Clear 02:34 54 45 2 356 (NNW) 196 - Mostly Cloudy 03:04 53 44 7 33 (NNE) 171 - Mostly Cloudy 03:34 54 44 7 38 (NE) 162 - Partly Cloudy 04:04 54 44 8 53 (NE) 133 - Mostly Cloudy 04:36 54 44 6 70 (ENE) 126 - Mostly Cloudy 05:01 54 44 5 81 (E) 151 - Mostly Cloudy ---=== TELESCOPE STATUS ===--- Stowed at 30 deg alt, engcam installed.
