APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday September 20, 2006 (MJD 53999) ---=== OBSERVING TEAM ===--- Swing: Elena Malanushenko Night: Jurek Krzesinski, Dan Long ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Recipe for Closed Telescope Suprise: Start with a liberal dose of cloud, add low level humidity, season with high wind to taste, stir well and wait for rain. After one hour in a 40 MPH driving rain, open door and check for dampness. To kick it up a notch, cover with absorbent pads and serve. ---=== OBSERVING LOG ===--- Afternoon Checkout: ------------------- 23:25Z There are heavy clouds on the sky, light rain in the afternoon. The temperature is around 10C, wind up to 25 mph, humidity 67.3% All systems are checked and work fine. Spectro focus has been adjusted for T=8.5C. The current spectro flat looks normal. I had to reset astrometric crate to get good biases. First two runs, 6379 and 6380, were bad, and 6381 is a good doghouse imager bias. By mistake I have named run 6380 as a "bias" instead of "ignore". 00:05Z Reset the DIMM black computer at the basement. Night: ------ 01:05Z Elena started a series of dithered flats while waiting on the clouds. Frames 40705-40711 are the flats, 12 and 13 are the arcs. 01:50Z Checked that DIMM was alive again. 02:15Z Doors Open, Fans On 06:15Z Doors Closed, Fans Off (started sprinkling) 09:00Z After about an hour of moderate rain being driven by 40 MPH west winds, the enclosure had a lot of water. There were puddles all along the west side and one could see where water had been forced through the west door up to a height of 6 feet or so. The lower enclosure had even more water. It was literally pouring from the ceiling in several spots around the edge of the rotating floor. There was water dripping off the west azimuth windbaffle motor. Nearly an entire box of absorbent pads were put down. 10:10Z Still cloudy/foggy/windy. We threw in several towels. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6379 22:09Z 22:14Z 100 O 41.03 42.33 22 ignore /bad 6380 22:24Z 22:27Z 100 O 44.81 45.72 20 ignore /bad 6381 22:41Z 23:06Z 100 O 49.06 55.51 56 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):y QA Procedures Done (y/n):y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 40697, plate -9999 ------- 22:35 40697 0.0 bias ----- sequence 40698, plate 2441 ------- 22:41 40698 10.0 flat 22:43 40699 2.0 arc 22:54 40700 2.1 arc 22:57 40701 2.1 arc ----- sequence 40702, plate -9999 ------- 00:15 40702 0.0 bias ----- sequence 40702, plate 2441 ------- 00:53 40703 10.0 flat 00:55 40704 2.0 arc 01:08 40705 10.0 flat 01:12 40706 10.0 flat 01:16 40707 10.0 flat 01:20 40708 10.0 flat 01:23 40709 10.0 flat 01:27 40710 10.0 flat 01:31 40711 10.0 flat 01:35 40712 2.0 arc 01:37 40713 2.0 arc ---=== 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 21:35Z 52 39 22 234 (SW) 511 - Cloudy 22:07Z 51 39 22 265 (W) 595 - Light Rain 22:38Z 48 40 12 265 (W) 581 - Light Rain 23:09Z 47 42 22 225 (SW) 485 - Light Rain 23:40Z 48 41 23 243 (WSW) 490 - Light Rain 00:10Z 49 39 17 250 (WSW) 526 - Cloudy 00:40Z 50 39 17 267 (W) 504 - Cloudy 01:12Z 50 39 19 254 (WSW) 546 - Cloudy 01:44Z 50 40 19 266 (W) 561 - Cloudy 01:56Z 50 40 18 259 (W) 549 - Cloudy 02:29Z 50 39 24 248 (WSW) 582 - Cloudy 03:01Z 50 39 23 260 (W) 536 - Cloudy 03:33Z 50 39 29 257 (WSW) 551 - Mostly Cloudy 04:05Z 50 40 32 254 (WSW) 570 - Cloudy 04:37Z 50 40 24 241 (WSW) 536 - Mostly Cloudy 05:09Z 49 41 28 257 (WSW) 588 - Mostly Cloudy 05:41Z 49 41 24 244 (WSW) 619 - Mostly Cloudy 06:14Z 49 41 34 239 (WSW) 609 - Sprinkles 06:46Z 46 44 35 243 (WSW) 933 - Light Rain 07:18Z 45 44 28 261 (W) 766 - Rain 07:50Z 45 45 24 287 (WNW) 75905 - Rain/Fog 08:22Z 45 45 34 286 (WNW) 8365 - Rain/Fog 08:54Z 43 44 34 287 (WNW) 4839 - Lt Rain/Fog 09:27Z 43 44 24 256 (WSW) 7486 - Fog 09:59Z 43 43 21 265 (W) 10369 - Fog ---=== TELESCOPE STATUS ===--- 02:15Z Doors Open, Fans On 06:15Z Doors Closed, Fans Off Stowed at 30 deg alt, cartridge 3 installed.
