APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday April 9, 2006 (MJD 53835) ---=== OBSERVING TEAM ===--- Jurek Krzesinski, Jian Ge, Suvrath Mahadevan, Xiaoke Wan (the ET crew) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Due to the weather condition, we opened in the socond half of the night but got two exposure on one plate in variable cloud conditions. Problems: --------- cart 8-th side wall with ET fibers outlets was falling off and we had problems to lock it in place (upper lock did not latch properly). We menaged to lock it after some work on the lock and secured the cartridge wall with a tape. ---=== OBSERVING LOG ===--- Sled1 replaced at afternoon. Night: ------ Clouds and dust till: 8:08. 09:00Z cart 8 plt E8026 (HD118203) mounted. Fk5 used to find the guide stars. The efficiency meter does not work since there is no ugriz magnitudes for the guide stars. We've got two 50 minutes exposures in variable cloud conditions. 1 spectro bias and no imager frames taken tonight. endNight done. ---=== 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 38574, plate -9999 ------- 02:14 38574 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 09:09Z E8026 214.06 0.0072 61.92 0.0038 52.49 -0.0113 1.000210 ---=== 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 ------------------------------------------------------------------------------ 09:09Z E8026 1.00021 -2074 -469 100 214 61.9 9.2 20 260 gdr 1.6 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:42Z 58 15 23 182 (S) 2427 - 23:14Z 59 15 30 204 (SSW) 2194 - 23:50Z 57 14 15 185 (S) 2212 - 00:22Z 56 13 16 212 (SSW) 2464 - 00:54Z 54 11 13 201 (SSW) 2246 - 01:26Z 53 11 20 218 (SW) 2435 - 01:59Z 53 11 13 200 (SSW) 2712 - 02:31Z 52 9 23 218 (SW) 2520 - 03:03Z 52 8 11 241 (WSW) 1927 - 03:35Z 52 8 13 215 (SW) 1880 - 04:07Z 52 7 14 216 (SW) 1916 - 04:39Z 52 8 15 218 (SW) 2226 - 05:12Z 52 8 12 211 (SSW) 2186 - 05:44Z 52 8 15 216 (SW) 2047 - 06:16Z 52 8 18 222 (SW) 2385 - 06:48Z 51 6 23 221 (SW) 2395 - 07:20Z 51 8 17 227 (SW) 2500 - 07:52Z 50 5 21 231 (SW) 2383 - 08:24Z 49 5 19 261 (W) 2272 - 08:55Z 48 4 17 265 (W) 1901 - 09:25Z 48 3 16 268 (W) 1457 - 09:55Z 48 3 15 264 (W) 1219 - 10:25Z 48 2 19 267 (W) 1113 - 10:55Z 48 5 13 264 (W) 900 - 11:26Z 47 4 17 267 (W) 1065 - ---=== TELESCOPE STATUS ===--- 03:30Z Doors opened, fans on. 06:40Z Doors closed, fans off (dust). 08:08Z Fans on.
