APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday February 25, 2007 (MJD 54157) ---=== OBSERVING TEAM ===--- Stephanie Snedden Dan Oravetz Suvrath Mahadevan (UF) Scott Fleming (UF) ---=== OBSERVING PLAN ===--- ET Science! ---=== OBSERVING SUMMARY ===--- Nine ET exposures done, but only 5 plates observed. Closed a little early because of high winds. ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems during afternoon checkout. IOP v4_30_0 was declared current. ET Night 1: ---------- 01:50Z Started with Cartridge 6, plate E8016 Guide stars with a usual +8 asec offset in Dec. One 50 minute exposure with iodine cell in and one 50 minute exposure with the cell out (template). 04:39Z Cartridge 9, plate E8017 Guide stars with cleared offsets One 50 minute exposure with iodine cell in and one 50 minute exposure with the cell out (template). 06:33Z Cartridge 3, plate E8024 Azimuth axis aborted partway through the slew. It took two axis init attempts to clear it. After that, we had guide stars at the end of the slew. One 50 minute exposure with iodine cell in and one 50 minute exposure with the cell out (template). 08:54Z Cartridge 5, plate E8025 Needed FK5 - offset in Dec of -10 approx. - And note we were west of the meridian. One 50 minute exposure with the iodine cell in and one 50 minute exposure with the cell out (template). 10:55Z Cartridge 1, Plate E8026 There was a delay while a large phase shift was corrected. We also closed the cartridge bay door to help keep the temperature stable in the plug lab. GSOGTF One 50 minute exposure with the iodine cell in. The wind gusts started exceeding 35 mph on a regular basis during this exposure. We let the exposure finish then closed. endNight rejoiced quickly. ---=== 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):N/A QA Procedures Done (y/n):N/A UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 43216, plate -9999 ------- 00:37 43216 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 08:54Z 5 8025 -14.07 -0.0017 59.31 -0.0030 168.14 -0.0158 1.000050 11:05Z 1 8026 199.81 -0.0004 67.22 -0.0010 28.66 -0.0133 1.000050 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 08:54Z 5 8025 1.00005 -494 820 75 -14 59.3 1.4 5 244 - 2.0 11:05Z 1 8026 1.00005 -494 878 150 200 67.2 -0.4 11 273 - 1.9 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:08Z 39 -2 6 274 (W) 145 - 22:40Z 41 1 2 277 (W) 176 - 23:12Z 39 4 4 270 (W) 211 - 23:54Z 35 5 7 254 (WSW) 262 - 00:26Z 36 5 2 181 (S) 353 - 00:58Z 34 5 4 248 (WSW) 431 - 01:31Z 34 4 1 270 (W) 353 - 02:02Z 34 4 3 264 (W) 400 - 02:32Z 34 4 2 234 (SW) 376 - 02:55Z 34 3 5 251 (WSW) 365 - 03:27Z 34 2 6 250 (WSW) 305 - 03:59Z 34 2 6 269 (W) 321 - 04:30Z 35 2 7 265 (W) 236 - 04:42Z 35 1 6 263 (W) 224 - 05:15Z 35 1 5 268 (W) 260 - 05:47Z 35 1 5 274 (W) 221 - 06:20Z 36 0 4 280 (W) 240 - 06:52Z 34 1 6 253 (WSW) 236 - 07:24Z 35 -1 7 261 (W) 204 - 07:57Z 35 0 5 255 (WSW) 216 - 08:29Z 34 0 4 263 (W) 235 - 09:01Z 34 0 5 259 (W) 252 - 09:33Z 33 1 8 257 (WSW) 269 - 10:05Z 32 1 6 268 (W) 281 - 10:37Z 32 3 9 265 (W) 316 - 11:09Z 31 3 12 274 (W) 462 - 11:41Z 30 3 11 274 (W) 578 - 12:13Z 30 2 13 271 (W) 458 - 12:45Z 29 2 11 264 (W) 1212 - ---=== TELESCOPE STATUS ===--- 01:00Z started ventilation 01:12Z opened enclosure 12300Z closed enclosure.
