APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday February 14, 2005 (MJD 53416) ---=== OBSERVING TEAM ===--- Steph Snedden Dan Long ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds prevented us from getting any data tonight. ---=== OBSERVING LOG ===--- Afternoon: ---------- Afternoon collimation check showed spectrographs wanting about +3000 mechPiston. As the enclosure is a little warmer than the expected nighttime temperature and the temperature is expected to be about the same as last night, we opted not to change things. Checkout went smoothly. Night: ------ 00:15Z Doors Open, Fans On 00:55Z Enclosure Open 01:30Z Cartridge 7 2070 SegueFaint105 01:45Z Fairly thick and variable cloud cover Guider efficiencies between 0 and 40%. 01:50Z preCalib 01:59Z first science 30908 Had to pause it after less than 5 minutes because of thick clouds. Resumed after about a 6 minute wait. More pausing and resuming. Reached nearly 30 minutes of elapsed time since exposure started, and read out with about 16 minutes of total exposure. SoS showed sky/sec of 2 and S/N of .2 -- declared bad. 02:30Z Clouds continue to thicken, fewer areas where guide stars are visible. 02:50Z Thick clouds and radar echoes not too far to the west. We decided to close for now. Doors open and fans still on. It was cloudy or mostly cloudy the rest of the night. 11:50Z We called it a night and ran endNight on cloudy night tapes. ---=== 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):y QA Procedures Done (y/n):y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 23:52 30901 0.0 bias ----- sequence 30902, plate 1667 ------- 23:59 30902 10.0 flat 00:01 30903 2.0 arc 00:05 30904 2.1 arc 00:07 30905 2.1 arc ----- sequence 30906, plate 2070 ------- 01:52 30906 10.0 flat 01:54 30907 2.0 arc 02:24 30908 962.3 target bad, low S/N ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:59Z 7 2070 -20.86 -0.0041 48.73 0.0021 162.37 -0.0228 1.000190 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JLCloudy1 Stays: JLCloudy2 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:59Z 7 2070 1.00019 -1875 -243 125 -21 48.7 4.4 12 262 - 1.9 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:27Z 41 1 13 265 (W) -9999 - Mostly Cloudy 00:02Z 42 7 12 266 (W) -9999 - Partly Cloudy 00:32Z 40 7 15 268 (W) -9999 - Partly Cloudy 01:04Z 39 11 10 265 (W) -9999 - Partly Cloudy 01:35Z 39 14 13 274 (W) -9999 - Partly Cloudy 02:08Z 40 15 5 270 (W) -9999 - Mostly Cloudy 02:41Z 39 16 13 297 (WNW) -9999 - Mostly Cloudy 03:13Z 39 19 17 301 (WNW) -9999 - Mostly Cloudy 03:45Z 38 21 10 267 (W) -9999 - Cloudy 04:18Z 40 16 13 257 (WSW) -9999 - Cloudy 04:50Z 40 16 16 257 (WSW) -9999 - Cloudy 05:22Z 38 19 13 265 (W) -9999 - Cloudy 05:54Z 39 17 14 259 (W) -9999 - Cloudy 06:27Z 40 16 12 299 (WNW) -9999 - Cloudy 06:59Z 39 17 3 276 (W) -9999 - Cloudy 07:31Z 38 18 13 266 (W) -9999 - Cloudy 08:04Z 38 18 19 264 (W) -9999 - Cloudy 08:36Z 37 13 11 263 (W) -9999 - Cloudy 09:08Z 37 12 9 271 (W) -9999 - Mostly Cloudy 09:40Z 36 12 12 262 (W) -9999 - Mostly Cloudy 10:13Z 36 15 11 266 (W) -9999 - Cloudy 10:45Z 36 15 9 268 (W) -9999 - Cloudy 11:17Z 38 14 10 284 (WNW) -9999 - Cloudy 11:49Z 37 14 9 270 (W) -9999 - Cloudy ---=== TELESCOPE STATUS ===--- 00:15Z Doors Open, Fans On 00:55Z Enclosure Open 02:50Z Enclosure Closed (fans still running) 11:50Z Doors Closed, Fans Off Stowed at 30 deg alt, cartridge 7 installed.
