APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday March 29, 2006 (MJD 53824) ---=== OBSERVING TEAM ===--- Swing: John Barentine Night: Olena Malanushenko Jurek Krzesinksi Visitor Haotong Zhans ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- No useful observations tonight. We had variations of wind 30-40 mph, dust between 1400-6000 counts, clouds from holes to overcast. All these obstacles happened one after another several times. No observations, no data, no cartridges, no problems. ---=== OBSERVING LOG ===--- Afternoon --------- Windy (>40 MPH wind gusts) and overcast during the afternoon. No problems during checkout. Spectro focus numbers are in the Problems section. Night ----- The wind up to 41 mph and dust up to 6800. We are waiting for better weather conditions. Cart 1, plate 2434 was mounted and we replaced it with Cart 4 plate 2359. 05:20Z Doors Open, Fans On, Louvers Open 05:30Z Enclosure is open Cart 4, plate 2359, Chunk, 2:27-8:27 T=4.7, wind 31.7 mph, humidity 48%, dust 1360, clouds. GTF on FK5 star. 6:26Z Pre-calibration Seeing 1.8", focus=260 6:34Z DoNextScience 1200 Wind is up to 35 mph, gust up to 40. Clouds, the efficiency became to be zero, and we stopped exposure after about 900 sec of observations. After reduction the exposure is declared as bad. 07:10Z. Enclosure is on because of strong wind. Waiting. Dust and wind are over limit, clouds. The weather improved 11:10 Enclosure is on Cart 8, plate 2135, 06:11-11:59, chunk Previous signal is 3.4 Needed FK5 Jurek tried to see stars, and sometimes he could see them but the seeing is 4" or more. 11:10 Enclosure is off. No useful observations today. endNight is completed using iop v4_18_0a. ---=== 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 38369, plate -9999 ------- 22:12 38369 0.0 bias 22:18 38370 0.0 bias ----- sequence 38371, plate 2135 ------- 22:31 38371 10.0 flat 22:33 38372 2.0 arc 22:37 38373 2.1 arc 22:39 38374 2.1 arc 22:58 38375 2.1 arc 23:00 38376 2.1 arc 23:29 38377 2.1 arc 23:31 38378 2.1 arc ----- sequence 38381, plate 2359 ------- 06:28 38381 10.0 flat 06:30 38382 2.0 arc 06:51 38383 910.7 target ----- sequence 38384, plate 2135 ------- 11:38 38384 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 06:44Z 2359 -79.31 -0.0115 73.18 -0.0008 110.22 -0.0087 1.000220 11:33Z 2135 272.85 -0.0021 56.89 -0.0014 111.36 -0.0142 1.000220 ---=== 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 ------------------------------------------------------------------------------ 22:27Z 2135 1.00008 -790 705 100 121 30.0 7.8 33 213 06:44Z 2359 1.00022 -2173 -413 260 -79 73.2 4.1 33 243 --1.8 11:32Z 2135 1.00022 -2173 -439 200 273 57.0 1.2 12 247 --4.0 or more ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:14Z 49 24 29 242 (WSW) 1710 - Clouds 21:50Z 47 24 22 229 (SW) 2219 - 22:20Z 48 25 29 199 (SSW) 3131 - 22:50Z 46 24 36 223 (SW) 4446 - 23:21Z 46 23 31 225 (SW) 5809 - 23:52Z 46 23 29 231 (SW) 5540 - 00:22Z 45 24 31 213 (SSW) 3883 - 01:43Z 44 18 30 217 (SW) 7029 - 02:15Z 44 19 31 241 (WSW) 5851 - 02:45Z 43 21 34 238 (WSW) 4175 - 03:15Z 43 21 28 240 (WSW) 4217 - 03:47Z 42 21 19 238 (WSW) 4375 - 04:19Z 42 20 26 238 (WSW) 3398 - 04:52Z 41 23 23 234 (SW) 2932 - 05:24Z 41 23 17 251 (WSW) 2121 - 05:56Z 40 21 31 237 (WSW) 1348 - 06:28Z 40 21 27 231 (SW) 1290 - 07:00Z 39 21 37 228 (SW) 1254 - 07:32Z 39 21 40 239 (WSW) 1241 - 08:05Z 38 21 27 237 (WSW) 1475 - 08:37Z 38 22 22 245 (WSW) 1585 - 09:09Z 37 23 22 255 (WSW) 1820 - 09:41Z 37 24 25 243 (WSW) 2172 - 10:13Z 37 23 35 239 (WSW) 1886 - 10:45Z 36 24 26 210 (SSW) 1631 - 11:16Z 34 25 18 259 (W) 1373 - Clouds 11:46Z 33 25 12 259 (W) 1606 - ---=== TELESCOPE STATUS ===--- 05:20Z Doors Open, Fans On, Louvers Open 05:30Z Enclosure is open 07:10Z.
