APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday April 23, 2007 (MJD 54214) ---=== OBSERVING TEAM ===--- Steph Snedden P.C. Guo (UF) Brian Lee (UF) ---=== OBSERVING PLAN ===--- ET! ---=== OBSERVING SUMMARY ===--- Lots of clouds and high wind. Two exposures on two ET plates is all we were able to get. The west latch and its sensor worked well tonight. ---=== OBSERVING LOG ===--- Afternoon: --------- Just like yesterday, when we set up in the afternoon, there was a VME error in Watcher for the astrom crate. Sure enough, the power to the boards was off. It looks like the ACDC Electronics 12V power supply is going bad. Jon says we should have a spare around. It needs replacing. A critical-high PR was filed. Otherwise, checkout was normal. sdsshost2 was rebooted for the start of the ET run last night after we ended shakeup. Night: ----- High winds delayed opening until 02:20Z. 02:50Z - Cartridge 5, plate 8025 - ET The cartridge would not latch under auto mode. There was no message under the root causes of the interlock logic. It latched without problems in manual mode. The clouds thickened shortly after starting the exposure. One 50 minute exposure was taken under mostly cloudy conditions. I doubt it is of any use. 04:02Z - Closed the enclosure because of clouds and nearby radar return. 07:25Z - Shut off ventilation because of rising humidity. 08:47Z - Started ventilation again. The wind stayed around closure limit while waves of cloud formed and dissipated. Then the clouds finally went away, but the wind gusts went over the limit. Very frustrating. Finally, the winds dropped. 10:14Z - We opened again for Cartridge 9, plate 8028 - ET One 50 minute exposure. 11:38Z - We closed. endNight rejoiced. ---=== 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 ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 03:37Z 5 8025 30.18 -0.0003 56.42 0.0025 204.97 -0.0124 1.000180 10:34Z 9 8028 134.33 0.0012 69.98 -0.0020 -58.69 0.0160 1.000050 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 03:37Z 5 8025 1.00018 -1778 -185 125 30 56.4 8.1 23 263 -- 2.0 10:34Z 9 8028 1.00005 -494 1073 350 134 70.0 -0.6 12 266 -- 2.4 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:25Z 58 14 35 204 (SSW) 1239 - partly cloudy 23:57Z 56 12 27 214 (SW) 1765 - ' 00:29Z 55 11 21 237 (WSW) 2706 - ' 01:01Z 52 11 36 230 (SW) 2844 - ' 01:34Z 50 10 22 237 (WSW) 1779 - mostly cloudy 02:06Z 48 10 26 217 (SW) 1325 - ' 02:38Z 48 10 25 239 (WSW) 1359 - ' 03:09Z 47 12 28 245 (WSW) 1414 - ' 03:41Z 46 12 23 247 (WSW) 1455 - ' 04:14Z 46 15 28 251 (WSW) 1299 - cloudy 04:46Z 44 19 21 271 (W) 1686 - ' 05:18Z 40 21 26 285 (WNW) 1778 - ' 05:50Z 39 22 26 283 (WNW) 1311 - ' 06:22Z 38 23 17 288 (WNW) 1650 - ' 06:55Z 34 28 12 16 (NNE) 1152 - ' 07:27Z 33 27 17 295 (WNW) 799 - ' 07:59Z 34 24 24 279 (W) 851 - ' 08:31Z 33 23 16 275 (W) 649 - mostly cloudy 09:03Z 32 23 24 266 (W) 589 - ' 09:36Z 32 21 21 274 (W) 614 - partly cloudy 10:08Z 31 18 23 278 (W) 562 - ' 10:39Z 30 21 10 298 (WNW) 524 - ' 11:11Z 29 20 17 303 (WNW) 438 - clear 11:43Z 28 15 11 316 (NW) 368 - ' ---=== TELESCOPE STATUS ===--- 01:45Z - Started building ventilation 02:41Z - Opened enclosure 04:00Z - Closed back up but left ventilation on. 07:25Z - Shut ventilation off because of rising humidity 08:46Z - Started ventilation again 10:14Z - Opened enclosure again 11:38Z - Closed enclosure Telescope stowed at 30 deg alt with cartridge 9 mounted.
