APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday April 8, 2006 (MJD 53834) ---=== OBSERVING TEAM ===--- Mike Harvanek Jian Ge, Suvrath Mahadevan, Xiaoke Wan (the ET crew) Kurt Biery (by phone) Steph Snedden (by phone) ---=== OBSERVING PLAN ===--- ET science! ---=== OBSERVING SUMMARY ===--- First half of the night was spent working on the ET instrument. Got on the sky around 07:44Z and observed 3 ET plates. The weather was good all night with a clear sky most of the time and only light clouds otherwise. However, the dust hovered between 2000 - 3000 counts from 08:00Z on. Perhaps a CO2 cleaning of the mirror is in order sometime soon. The spectro frame pool filled up. See the main log for details. ---=== OBSERVING LOG ===--- Afternoon: ---------- The initial spectro bias failed because there was no room in the frame pool: sp1> goStare 0 -init -bias PlateId [-9999]: 2006-04-09 00:58:08Z: setting cameraSet(lines) 2070 Error: {sd1 {Insufficient space in the Frame Pool}} sp1> Is this the old problem where the frames in the pool refuse to be overwritten even though the overwrite flag is set to "yes"? I called Kurt Biery so that he could catch this problem in the act. However, I could not reach Kurt. Because the initial spectro bias failed, the "init" part did not get done. This caused the following problems: sp1> startMon 2006-04-09 01:01:58Z: mkdir: cannot create directory `/data/spectro/53834/guider/': No such file or directory sp1> gcam 3 2 sp1> 2006-04-09 01:02:50Z: mkdir: cannot create directory `/data/spectro/53834/guider/': No such file or directory sp1> I called Steph Snedden and after some discussion we agreed that if Kurt had not been reached by the time ET was ready to go on the sky, I should just do an "initNight -poolInit" to clear the pool. Kurt returned my call around 02:50Z. We tried an experiment (ask Kurt for the details) but had trouble getting sd1 to come back after it was rebooted. We finally got sd1 back up and decided to stop debugging. We didn't want things broken when ET was ready to go on sky and the debugging will be more productive when Jon Brinkmann is available to assist (i.e., Monday morning). To make room in the frame pool, I deleted 15 frames using poolDelFrame (frames 38322-38330 from mjd 53822 and frames 38385-38390 from mjd 53825). Hopefully, this will be enough space until Monday morning when Kurt will look at this again. The az fiducial at 137 degrees did not read in either direction. Night: ------ Clear at sunset. The enclosure was removed around 02:00Z. Work continued on the ET instrument and delayed our getting on the sky. 07:44Z Plate 8021 (cartridge 3): HD143291. Guide stars on the gotoField. Seeing is highly variable (1.5 - 3.5"). The seeing finally settled down to around 1.5 - 2". Guide stars in fibers 7 and 8 had much higher fwhms though. Fiber 7 was typically 2.5 - 3" and fiber 8 was > 3" when it was able to be measured (which was not often). This was definitely NOT a focus problem. 09:35Z Plate 8022 (cartridge 4): HD149026. Needed an fk5 to acquire the field. The seeing has improved to around 1.2". 10:56Z Plate 8027 (cartridge 9): Kepler. Needed an fk5 to acquire the field. The seeing is around 1.5 - 1.6". The sky was clear most of the night with occasional light clouds. The weather was good in general but the dust hovered between 2000 - 3000 counts from 08:00Z on. Perhaps a CO2 cleaning of the mirror is in order sometime soon. endNight (iop v4_18_0a) rejoiced. Note that no imaging data (not even a test bias) were obtained tonight. ---=== 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): YES QA Procedures Done (y/n): N/A UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 38571, plate 2077 ------- 04:02 38571 0.0 bias 38572 0.0 bias DA reboot 04:14 38573 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 08:07Z 3 8021 84.38 0.0014 66.90 0.0055 250.89 0.0148 1.000200 09:50Z 4 8022 131.98 0.0077 81.19 0.0065 -53.00 0.0483 1.000100 11:06Z 9 8027 126.92 0.0022 68.74 0.0056 -67.91 0.0117 1.000040 ---=== 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 ------------------------------------------------------------------------------ 08:06Z 3 8021 1.00020 -1975 -497 0 85 66.7 5.9 1 184 ---- 1.5" 09:49Z 4 8022 1.00010 -988 300 0 131 81.0 7.1 1 145 ---- 1.2" 11:05Z 9 8027 1.00004 -395 807 0 127 68.6 7.5 1 174 ---- 1.6" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:58Z 56 12 14 223 (SW) 1812 - 23:30Z 51 11 5 256 (WSW) 1875 - 00:02Z 48 7 6 233 (SW) 1872 - 00:34Z 49 7 3 190 (S) 1850 - 01:05Z 48 9 10 208 (SSW) 1964 - 01:38Z 45 8 8 185 (S) 1760 - 02:10Z 45 10 7 181 (S) 1676 - clear 02:42Z 45 10 9 179 (S) 1797 - clear 03:14Z 43 13 6 166 (SSE) 1611 - clear 03:46Z 44 12 12 144 (SE) 1780 - clear 04:16Z 45 5 6 184 (S) 1763 - clear 04:49Z 46 4 6 182 (S) 1805 - clear 05:21Z 45 3 6 187 (S) 1820 - thin clouds 05:53Z 45 7 11 203 (SSW) 2101 - thin clouds 06:25Z 45 8 9 182 (S) 1896 - thin clouds 06:57Z 44 12 9 181 (S) 1898 - thin clouds 07:30Z 43 9 6 184 (S) 1986 - clear 08:01Z 43 11 4 175 (S) 1910 - clear 08:33Z 43 6 1 146 (SE) 2304 - clear 09:06Z 46 4 1 157 (SSE) 2615 - clear 09:38Z 44 3 0 206 (SSW) 2384 - clear 10:10Z 46 3 0 163 (SSE) 2469 - clear 10:42Z 45 3 5 203 (SSW) 2515 - clear 11:15Z 45 2 1 173 (S) 2660 - clear 11:47Z 45 2 2 180 (S) 3115 - thin clouds 12:19Z 44 1 2 141 (SE) 2955 - thin clouds 12:51Z 44 2 3 179 (S) 3000 - thin clouds ---=== TELESCOPE STATUS ===--- 01:55Z Enclosure doors opened, fans and blowers on, louvers opened. 02:00Z Enclosure off. 12:30Z Enclosure on, doors closed, fans and blowers off, louvers closed.
