APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday September 13, 2008 (MJD 54723) ---=== OBSERVING TEAM ===--- Steph Snedden (observer) Dmitry Bizyaev (observer) Marvels team: Jian Ge Scott Fleming Brian Lee ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Night was partly cloudy in its first part and with critical humidity in the second. tmicro (Disconnected Sensor in M2B3:: 2008-09-14 all time) We obtained useful data points with MARLELS cartridges 3031, 3032, and 3033. ---=== OBSERVING LOG ===--- Afternoon: ---------- ntp_check ok iccSoundOff ok imager bias ok We cannot check anything else since the pump is connected to the sp1. Night: ------ 00:17Z ventilation started Humidity dropped down at the evening, and clouds became thinner. We asked to disconnect the pump from sp1, it was doen, but in the process the SErail stop button was pushed. As a result, telescope passed 90 degree limit and got stuck there. Wet ried different combinations of interlocks; what really helped was ""ALT motor down" interlock. --- Cartridge 8, plate 3032 mounted. 02:53Z enclosure off, almost no clouds. 03:02Z gotoField with cart. 8 fk5 star used MARVELS team controls their exposures. --- 04:07Z Cart. 9 plate 3033 mounted, fk5 used 05:39Z telescope sent to the stove position; sp1 force filled. Dewar on imager was changed. Cart. 3 plate 3031 mounted. 06:29Z Cart. 8 plate 3032 is mounted again GSOGTF The next message was repeated many times: Failed to send message to tCmdLog (2008-09-14 07:28:18Z sdssmcp) (Failed to send message to tCmdLog (2008-09-14 07:28:18Z sdssmcp): 2008-09-14 07:28:22Z ) 08:17Z humidity jumped up to 80%, clouds with rain and lightnings are approaching. We close the enclosure. 08:32Z ventilation stopped, doors closed, humidity is around 80-86%. 10:56Z sp1 dewar was filled 11:03Z endNight rejoiced ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7684 23:26Z 23:41Z 100 O 54.06 57.72 34 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 54565, plate -9999 ------- 03:29 54565 0.0 bias 03:38 54567 0.0 bias 03:41 54568 0.0 bias 03:44 54569 0.0 bias 04:24 54570 0.0 bias 04:51 54571 0.0 bias 04:59 54572 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 03:15Z 8 3032 202.55 -0.0006 71.77 -0.0016 29.51 0.0201 1.000160 04:48Z 9 3033 67.31 -0.0001 65.09 0.0008 236.01 0.0200 1.000210 06:19Z 3 3031 159.59 0.0004 47.20 -0.0010 -54.35 0.0177 1.000210 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 23:39Z 9 3033 1.00000 1 1257 0 121 30.4 13.2 4 352 -- 1.2" 04:48Z 9 3033 1.00021 -2073 -576 0 67 65.1 11.9 12 71 -- 1.6" 06:19Z 3 3031 1.00021 -2073 -526 0 160 47.2 11.7 10 86 -- 1.8" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:34Z 56 38 10 329 (NNW) 694 - 00:05Z 54 40 5 338 (NNW) 727 - some clouds 00:35Z 54 40 7 354 (NNW) 892 - '' 01:05Z 53 40 2 4 (N) 796 - '' 01:36Z 53 38 6 8 (N) 952 - '' 02:06Z 49 40 6 1 (N) 760 - '' 02:36Z 50 38 3 356 (NNW) 615 - '' 03:06Z 53 37 6 9 (N) 523 - mostly clear 03:39Z 53 36 10 32 (NNE) 712 - '' 04:11Z 53 35 16 58 (ENE) 706 - clouds coming 04:43Z 53 38 12 80 (E) 592 - '' 05:15Z 53 37 10 79 (E) 629 - '' 05:46Z 53 37 11 79 (E) 798 - '' 06:18Z 52 39 10 87 (E) 700 - '' 06:51Z 52 40 11 82 (E) 723 - '' 07:23Z 51 41 12 82 (E) 642 - '' 07:55Z 49 42 17 70 (ENE) 724 - more clouds 08:27Z 49 44 15 71 (ENE) 870 - '' 08:59Z 48 45 12 74 (ENE) 1188 - '' 09:31Z 48 46 7 93 (E) 1610 - '' 10:03Z 47 46 12 82 (E) 1636 - '' 10:35Z 47 47 15 76 (ENE) 1791 - '' 11:08Z 48 46 8 85 (E) 2075 - ---=== TELESCOPE STATUS ===--- 00:17Z - Began ventilation.
