APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday December 19, 2006 (MJD 54089) ---=== OBSERVING TEAM ===--- Howard Brewington (Days) Dan Long and Steph Snedden (Observers) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Snow! Also, high humidity followed by high wind speeds and blowing snow. Then ... more snow. Approximately five inches of snow had fallen by 11:00Z During the afternoon, the astrometric crate was unavailable and had to be rebooted. Several hours later, id6 stopped responding and was rebooted. The PT hand paddle nearest the console has a sticky button (see afternoon log section). French, Dan and Steph moved snow around with shovels and the Kubota. The wind moved it back. ---=== OBSERVING LOG ===--- Afternoon: ----------- I had to reboot the astro crates; see the Problems Section for the error message. I had to logout the ports of the PT because I was unable to do an iack. Also, when I did test slews via the north-wall hand paddle, the west-slew button was sticking. In other words, a west slew was possible by just pressing the slew button instead of holding down the west button and then pressing the slew button. The Spectro collimation/focus was checked but not adjusted; see Problems Section for numbers. The focus is set for ~4-degrees C. While moving full dewars into the enclosure before the winter storm, one of the wheels fell off the dolly. I left it just inside the 2.5-meter enclosure. French knows. night: ---------- The snow we've been warned about finally arrived. Tried again to do imager cals. The aflux problem last night was just Steph reading the wrong value in the IOP status return. aflux is fine, but tonight, we had a different problem. The encoder LCD display would not display a number. All the LCD number elements were lit, but hitting the reset button did not set the display to zero. Shannon was contacted. He will come in tomorrow afternoon and see if the behavior is different at warmer ambient temperatures, as a first step. Part of the night was spent doing snow removal. 06:57Z - id6 stopped responding while doing nothing. We rebooted it. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6632 22:19Z 22:51Z 100 O 132.23 140.40 69 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):n QA Procedures Done (y/n):n UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 42058, plate 2580 ------- 22:13 42058 10.0 flat 22:15 42059 2.0 arc 22:27 42060 3.0 arc 22:30 42061 3.0 arc ----- sequence 42062, plate -9999 ------- 23:40 42062 0.0 bias 23:43 42063 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 ===--- ---=== 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 19:52Z 30 31 13 178 (S) 13631 - cloudy 20:25Z 30 31 20 192 (SSW) 34193 - ' 20:57Z 30 30 16 202 (SSW) 12804 - ' 21:29Z 30 30 24 178 (S) 781 - ' 22:01Z 30 29 30 195 (SSW) 631 - ' 22:32Z 30 28 30 176 (S) 643 - ' 23:03Z 30 30 20 217 (SW) 9892 - ' 23:35Z 26 25 14 271 (W) 1762 - snow 00:07Z 21 21 10 296 (WNW) 169 - ' 03:05Z 19 18 17 283 (WNW) 715 - ' 03:37Z 19 18 18 300 (WNW) 1117 - ' 04:10Z 18 17 13 279 (W) 711 - ' 04:42Z 18 17 19 264 (W) 639 - ' 05:14Z 19 18 20 251 (WSW) 6608 - ' 05:46Z 19 18 20 266 (W) 4141 - ' 06:22Z 20 18 20 268 (W) 1693 - ' 06:54Z 20 18 19 254 (WSW) 992 - ' 07:26Z 19 14 19 251 (WSW) 525 - ' 07:59Z 18 15 25 229 (SW) 1092 - ' 08:31Z 18 15 20 243 (WSW) 427 - ' 09:03Z 18 15 16 245 (WSW) 273 - ' 09:35Z 17 15 15 239 (WSW) 265 - ' 10:07Z 17 14 21 241 (WSW) 195 - ' 10:39Z 16 13 13 264 (W) 511 - ' ---=== TELESCOPE STATUS ===--- Never opened.
