Addendum: I forgot to add Nathan to observing team. Sorry. --------------------------- APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday March 4, 2009 (MJD 54895) ---=== OBSERVING TEAM ===--- Viktor Malanushenko Elena Malanushenko Kaike Pan (Swing) Marvels: Nathan De Lee ---=== OBSERVING PLAN ===--- Science! 4 Mar 2009 54895.0 0.57 MARVELS until 09:21 (7.4 h), then SEGUE (2.7 h) ---=== OBSERVING SUMMARY ===--- It was cloudy night. We kept telescope opened but could not get any useful signal last night. ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems were checked and working properly. The spectro focus was checked but no adjustment made. The best focus is still set for about 8 C. Night: ------ Clouds, 34 mph wind, ~3K dust. We delayed the opening until dust and wind trended down. 01:20 Z - enclosure is off. Cart 3, plate 3209 is mounted Could not find guider stars. Found FK5 but it was weak because of clouds. Waiting. We did not observe this cartridge and it expired. 4:24Z Mounted cart 5 plate 3217, Marvels Field A. Used FK5 and even spiralPattern to find FK5. We can see stars with efficiency ~0-5%, still overcast. 05:30Z calibration 06:23Z science exposure - efficiency was variable 0-70% but mostly very low. Exposure was not good. 07:15 - calibration Cart 4, plate 3091. Clouds, we even did not go to field. Waiting. 09:00 Cart 8 plate 3243 is mounted. We are waiting for clouds to go away. Put telescope to stow to wait. 10:47 Cart 2 plate 3245 Used FK5 to find guider stars, but could not see stars after that because clouds. 12:00 endNight is finished. 12:10 enclosure is on. ---=== 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 59598, plate -9999 ------- 23:35 59598 0.0 bias ----- sequence 59599, plate 3209 ------- 23:41 59599 10.0 flat 23:44 59600 2.0 arc 23:49 59601 3.0 arc 23:52 59602 3.0 arc ----- sequence 59604, plate -9999 ------- 00:32 59604 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 06:27Z 5 3217 205.04 0.0114 69.75 0.0041 34.07 0.0096 1.000060 12:07Z 2 3245 121.00 -0.0007 29.93 0.0010 0.00 0.0000 1.000060 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 06:27Z 5 3217 1.00006 -591 716 75 205 69.8 7.7 19 252 -- 1.6 12:07Z 2 3245 1.00006 -591 842 75 121 29.9 5.8 21 270 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:04Z 50 18 19 263 (W) 279 - 23:36Z 53 20 27 266 (W) 223 - 00:08Z 51 19 17 267 (W) 314 - 00:57Z 49 21 28 277 (W) 2832 - 01:29Z 48 21 19 257 (WSW) 3720 - 02:01Z 48 21 17 267 (W) 1420 - 02:31Z 48 21 21 262 (W) 589 - 03:01Z 49 21 23 269 (W) 440 - 03:40Z 48 21 18 260 (W) 430 - 04:10Z 47 21 26 264 (W) 465 - 04:41Z 47 21 19 263 (W) 388 - 05:11Z 47 21 25 275 (W) 345 - 05:42Z 46 21 22 266 (W) 349 - 06:14Z 45 21 22 261 (W) 324 - 06:46Z 45 21 23 249 (WSW) 296 - 07:18Z 44 21 22 249 (WSW) 296 - 07:51Z 44 21 28 250 (WSW) 276 - 08:23Z 44 21 20 259 (W) 276 - 08:55Z 43 21 21 265 (W) 284 - 09:27Z 43 19 16 267 (W) 284 - 09:58Z 42 20 25 272 (W) 263 - 10:28Z 42 18 25 262 (W) 255 - 10:59Z 42 19 23 267 (W) 282 - 11:30Z 42 20 17 270 (W) 310 - 12:03Z 42 20 21 271 (W) 330 - ---=== TELESCOPE STATUS ===--- 23:50Z - Began ventilation.
