APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday January 25, 2004 (MJD 53030) ---=== OBSERVING TEAM ===--- Afternoon: Steph Snedden Jurek Krzeinski Howard Brewington Night: Mike Harvanek Atsuko Nitta ---=== OBSERVING PLAN ===--- Science ---=== OBSERVING SUMMARY ===--- Snow removal, snow removal and more snow removal. ---=== OBSERVING LOG ===--- In the afternoon, o Steph rebooted HOST and removed snow so that Atsuko can get to the ops building from her dorm room. o Norm called Jurek and asked him to replace the dewars at 12:50pm. Jurek, Jose (Sunspotter) and Howard came to replace the imager dewar. Spectro dewar did not need any replacement. o Jurek did some snow removal so that we can open the ops building front door. o The snow plower removed snow nicely all through the APO drive way to the lower parking lot. (The upper lot is not plowed as well as the lower lot.) Night ======= We worked on snow removal. With the snow falling and the wind (sometimes gusting up to over 40m/h) blowing the snow around, it felt like a loosing battle. Jack ran the Kubota while Mike did power shovelling with his arms. Atsuko did her best but she totally lacks power compared to the other two -- she gets a out 1m^2 done while Mike gets 10 m^2 done. If there is a snow removal olympic game, Mike will get the gold medal for sure. While trying to scrape as much snow/ice from the concrete, the handle part broke off from one of the metal shovels and another metal shovel's handle broke into two. The plastic shovels are light and nice but not very good in scraping. At this time (10:30Z), there is a good path between op bldg to the enclosure/plug bldg, ops bldg to the dorms. The loading dock, the ops bldg front door area, the enclosure area are all cleared. Jack worked on the upper parking lot a bit. ODH sensor goes off once in a while. We can see the alarm go off from the control room as the lights outside the enclosure starts flashing. French called to see how we are doing with the snow removal. He said that he will make sure someone will come up to remove snow in the afternoon so that if it is clear tomorrow night, we can observe. Spectro dewar pressure slowely rose from about 13lb to close 17lb, but it seems to be declining again. if you want to plot the behavior of the spectro pressure, the TPM variable name is tpm_LN2press_spectro (or look at spectropressure.ps in my home directory on sdsshost). endNight ran on cloudy tapes and finished successfully. ---=== 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 24784, plate -9999 ------- 00:38 24784 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== 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 ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:34Z 25 20 29 270 (W) -9999 - 23:06Z 25 20 22 283 (WNW) -9999 - 23:38Z 24 20 23 267 (W) -9999 - 00:10Z 24 20 21 265 (W) -9999 - 00:43Z 24 20 23 255 (WSW) -9999 - 01:15Z 24 20 21 274 (W) -9999 - 01:47Z 24 21 24 276 (W) -9999 - 02:20Z 24 21 25 261 (W) -9999 - 02:52Z 24 20 30 253 (WSW) -9999 - 03:28Z 23 20 34 262 (W) -9999 - 04:00Z 23 20 34 246 (WSW) -9999 - 04:32Z 24 20 26 267 (W) -9999 - 05:05Z 23 20 16 270 (W) -9999 - 05:41Z 24 20 25 298 (WNW) -9999 - 06:13Z 23 20 17 268 (W) -9999 - 06:46Z 23 19 27 273 (W) -9999 - 07:18Z 22 18 13 330 (NNW) -9999 - 07:50Z 19 15 13 321 (NW) -9999 - 08:22Z 17 13 20 335 (NNW) -9999 - 08:54Z 15 11 24 350 (NNW) -9999 - 09:27Z 14 8 19 22 (NNE) -9999 - 09:59Z 13 7 28 7 (N) -9999 - 10:35Z 12 6 4 358 (NNW) -9999 - ---=== TELESCOPE STATUS ===--- Telescope at stow with spectro autofll connected.
