APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday May 5, 2005 (MJD 53496) ---=== OBSERVING TEAM ===--- Swing: Dan Long Night: Scot Kleinman Atsuko Nitta ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds/lightening/wind delayed our opening until 09:50Z. 2 plates finished. ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems with the afternoon check. Spectrograph focus checked and adjusted so best focus is about 2 C warmer than last night, or about 9 C. Focus details in the problems section. Night: ------ delayed opening due to the clouds that contained rain and lightening. 02:40Z Started the fansi and cracked the doors. Once the northern clouds moved away, we start seeing clouds with rain moving from the south towards us (between ELP and us). we wait. Lightening is close to us. We wait more. The humidity is climbing too. 06:50Z Now we got high wind. so we closed the doors of the enclosure. 08:50Z The storm has moved away from us. It looks like we can open and start getting data! The dew point diff is 4.5C so we will keep an eye on the humidity. We did not fill the spectros since the last fill was between 01:30Z and 01:45Z. There should be enough Ln2 until twilight which is in couple hours. Cart 4 Plate 1576 ------------------ This is a high priority (pri 4) plate. GSOGTF. :) The seeing is about 1.2". We got two exposures. Combined with the exposures from previous night, we finished this plate. 09:50Z Time to go to the next plate! Cart 8 Plate 1578 ------------------ Another high priority (pri 4) plate. The humidity is creeping up. GSOGTF! The third exposure was taken in the twilight. We finished this plate with 3 exposures. The humidity rose up to dew point diff 3K, but never below. r1 got badsky residuals and max sky-residuals warnings from SoS. endNight ran happily. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== 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):y QA Procedures Done (y/n):y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 22:09 32556 0.0 bias 22:19 32557 10.0 flat 22:21 32558 2.0 arc 22:30 32559 2.0 arc collimation 22:33 32560 2.1 arc collimation 22:49 32561 2.1 arc " 22:52 32562 2.1 arc " 23:04 32563 10.0 flat 23:07 32564 2.0 arc ----- sequence 32565, plate -9999 ------- 01:30 32565 0.0 bias ----- sequence 32566, plate 1576 ------- 02:08 32566 0.0 bias ----- sequence 32566, plate 1576 ------- DONE 02:08 32566 0.0 bias 09:10 32567 10.0 flat 09:12 32568 2.0 arc 09:30 32569 900.1 target 09:48 32570 900.1 target ----- sequence 32571, plate 1578 ------- DONE 10:00 32571 10.0 flat 10:03 32572 2.0 arc 10:21 32573 900.1 target 10:39 32574 900.2 target 10:56 32575 900.1 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 09:19Z 4 1576 -64.76 0.0003 76.64 0.0004 121.79 0.0116 1.000100 10:13Z 8 1578 269.48 0.0015 63.40 0.0003 105.51 -0.0079 1.000100 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL Stays: JL ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 09:19Z 4 1576 1.00010 -988 329 25 -65 76.7 8.0 8 182 gdr 1.2 10:13Z 8 1578 1.00010 -988 402 75 269 63.4 7.6 14 170 gdr 1.3 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:33Z 57 34 18 225 (SW) 830 - Partly Cloudy 23:05Z 62 36 8 181 (S) 802 - Partly Cloudy 23:35Z 55 34 14 180 (S) 927 - Sprinkles 00:05Z 54 35 18 147 (SSE) 920 - Mostly Cloudy 00:36Z 53 35 19 126 (SE) 935 - Partly Cloudy 01:06Z 49 39 22 128 (SE) 1036 - Sprinkles 01:36Z 48 39 22 127 (SE) 823 - Mostly Cloudy 02:06Z 48 38 25 138 (SE) 804 - Partly Cloudy 02:33Z 48 39 30 132 (SE) 837 - 03:03Z 47 39 27 127 (SE) 1068 - 03:33Z 48 38 24 134 (SE) 794 - 04:03Z 48 38 18 113 (ESE) 790 - 04:34Z 47 38 22 127 (SE) 829 - 05:04Z 47 39 22 130 (SE) 812 - 05:34Z 47 39 21 130 (SE) 767 - 06:04Z 48 38 15 169 (S) 907 - 06:34Z 45 39 23 142 (SE) 596 - 07:05Z 46 37 29 132 (SE) 569 - 07:37Z 45 38 18 137 (SE) 694 - 08:09Z 47 38 23 191 (S) 817 - 08:41Z 46 37 18 161 (SSE) 806 - Party cloudy 09:13Z 46 37 15 162 (SSE) 822 - 09:45Z 45 38 15 174 (S) 789 - 10:16Z 45 38 14 169 (S) 833 - 10:46Z 44 38 12 167 (SSE) 751 - 11:19Z 44 39 17 197 (SSW) 837 - ---=== TELESCOPE STATUS ===--- 02:20Z Started the fans, cracked doors. 06:50Z CLosed the doors and fans.
