APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday May 1, 2009 (MJD 54953) ---=== OBSERVING TEAM ===--- Howard Brewington Kaike Pan ---=== OBSERVING PLAN ===--- SEGUE2 Science! ---=== OBSERVING SUMMARY ===--- We never open tonight because of thick clouds. Watcher complained on temperature of red chip of SP2 when it was -95 C. Is it too cold? ---=== OBSERVING LOG ===--- Afternoon: ---------- 23:00Z Started the checkout 23:35Z Started the spectro collimation check. Focus was not adjusted; it's set for about 12-degrees C. Collimate's results are posted in the Problem Section. 23:36Z Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 118G 18G 88% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 853G 18G 98% /data sdssfiles1p:/data1/data 1.5T 657G 736G 48% /files 23:40Z Completed the apo_plotbias; results posted in Prob Section 01:45Z Sunset with thick clouds. Removed data from mjd 54942-46. Thick clouds. Night: ------ It was overcast at sunset. 03:13Z Evening twilight 05:40Z Watcher complained on the temperature of CCD 02, the red chip of spectrograph2. Watcher reports a temperature 0f -95 C when SoP "cc tcheck" reports -94 C. Is the temperature too cold? 08:16Z Moonset 10:46Z Morning twilight 10:15Z It was still overcasting. It's only 30 min from twilight, we decided to call it night. 10:15Z endNight rejoiced. 12:18Z Sunrise ---=== 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 23:37 60964 10.0 flat 23:39 60965 2.0 arc 23:45 60966 2.0 arc 23:47 60967 3.0 arc ----- sequence 60968, plate -9999 ------- 00:57 60968 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 23:25Z 60 16 7 256 (WSW) 1222 - Thick clouds 23:57Z 60 16 11 263 (W) 1336 - 01:10Z 58 14 15 248 (WSW) 1402 - 01:40Z 57 13 10 262 (W) 1289 - 02:10Z 56 11 8 253 (WSW) 1382 - 02:42Z 56 11 9 266 (W) 1300 - 03:15Z 56 11 10 264 (W) 1403 - 03:45Z 56 12 6 261 (W) 1412 - 04:19Z 56 11 9 265 (W) 1442 - 04:51Z 56 10 13 269 (W) 1419 - 05:22Z 56 10 12 279 (W) 1453 - 05:54Z 55 10 15 267 (W) 1493 - 06:28Z 55 8 18 264 (W) 1463 - 07:00Z 54 8 16 275 (W) 1468 - 07:31Z 55 8 18 275 (W) 1532 - 08:04Z 54 9 11 263 (W) 1546 - 08:35Z 53 9 12 231 (SW) 1532 - 09:05Z 53 8 14 259 (W) 1573 - 09:37Z 53 7 14 264 (W) 1606 - Thick Clouds ---=== TELESCOPE STATUS ===--- Never open due to clouds.
