APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday February 28, 2007 (MJD 54160) ---=== OBSERVING TEAM ===--- Steph Snedden Audrey Simmons Scott Fleming (UF) Suvrath Mahadevan (UF) Dan Oravetz French Leger (visiting) ---=== OBSERVING PLAN ===--- ET Science! ---=== OBSERVING SUMMARY ===--- Five exposures on four plates after the dust and wind gusts dropped. Note the temperature was near the closure limit, yet we had no trouble with the rotator. If last night's problems were friction related, I would think we would have had more problems tonight. ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems during checkout. Night: ----- We had high dust and wind to start the night. Note that with the enclosure on, the 2.5m anemometer reported 30-40 mph gusts when they were certainly over 50 mph, with the wind out of the west. 07:00Z - The winds dropped enough that we risked opening. 07:21Z - Cartridge 5, plate E8025 No guide stars. Had an FK5 at the edge of fiber 10, then lost it on a 5 asec offset and couldn't find it again. I then found it with spiralPattern 20 asec away. Odd. Could this somehow be an effect of cold weather and/or wind (it was -10C and gusts to 30 mph)? One 50 minute exposure. 08:40Z We got the usual CCD 55 vs+ watcher error at T=-10.8C 08:53Z Cartridge 1, plate E8026 GSOGTF with the offsets from the previous plate. One 50 minute exposure 09:50Z Cartridge 8, plate E8021 GSOGTF with the previous offsets in. One 50 minute exposure. 10:49Z Cartridge 7, plate E8022 GSOGTF with the previous offsets. Two 50 minute exposures, one with the Iodine cell in and one template. Cals were taken and then we closed. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- ---=== LTMATCH RESULTS ===--- ---=== SPECTROSCOPY DATA SUMMARY ===--- ----- sequence 43219, plate 8016 ------- 02:23 43219 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- 07:52Z 5 8025 11.07 -0.0030 59.58 -0.0080 189.24 -0.0108 1.000000 08:53Z 1 8026 154.51 -0.0003 65.74 -0.0060 -37.66 -0.0165 1.000000 10:12Z 8 8021 89.04 -0.0032 60.77 -0.0052 251.70 -0.0015 0.999920 10:58Z 7 8022 111.48 -0.0029 65.06 -0.0043 -86.36 -0.0073 0.999990 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- 07:52Z 5 8025 1.00000 0 1653 500 11 59.6 -10.4 6 278 - 2.3 08:53Z 1 8026 1.00000 0 1489 350 155 65.7 -10.9 6 266 - 2.1 10:11Z 8 8021 0.99992 790 2205 400 89 60.5 -11.6 3 185 - 1.7 10:58Z 7 8022 0.99999 99 1523 300 111 65.1 -11.8 3 115 - 1.7 ---=== WEATHER LOG ===--- 01:30Z 25 5 13 263 (W) 12774 - clear 02:02Z 24 5 14 271 (W) 8687 - ' 02:33Z 23 2 15 271 (W) 8060 - ' 03:05Z 22 0 15 273 (W) 3301 - ' 03:37Z 21 2 14 274 (W) 3863 - ' 04:25Z 19 3 12 272 (W) 1734 - ' 04:58Z 18 2 12 264 (W) 1780 - ' 05:30Z 17 2 13 280 (W) 1779 - part cloudy 06:02Z 15 3 11 278 (W) 1194 - ' 06:34Z 14 1 9 272 (W) 624 - clear 07:06Z 14 2 5 230 (SW) 626 - ' 07:40Z 13 4 8 272 (W) 535 - ' 08:12Z 13 3 5 272 (W) 491 - part cloudy 08:42Z 12 4 4 167 (SSE) 545 - clear 09:12Z 12 4 4 250 (WSW) 488 - ' 09:45Z 11 4 3 136 (SE) 471 - part cloudy 10:15Z 11 4 3 161 (SSE) 464 - clear 10:45Z 11 4 3 138 (SE) 457 - ' 11:18Z 10 3 5 15 (NNE) 429 - ' 11:49Z 10 2 2 196 (SSW) 330 - ' 12:21Z 10 2 5 141 (SE) 344 - ' 12:53Z 10 2 4 98 (E) 345 - ' ---=== TELESCOPE STATUS ===--- 04:27Z - Started building ventilation.
