APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday May 9, 2009 (MJD 54961) ---=== OBSERVING TEAM ===--- Dan Oravetz Dmitry Bizyaev ---=== OBSERVING PLAN ===--- Marvels Science, shakedown if clouds will come ---=== OBSERVING SUMMARY ===--- Clear night, decent seeing in the beginning, humidity rising and more dusty after ~ 6:30Z. Some pollen in the air after ~ 7Z. We closed earlier because of high dust in combination with rising humidity and bad seeing. Exposed Marvels plates: 3413 A - there are some missing fibers, and they loor strange (no lines, but there is some kind of signal there, and each profile (cross-section of the spectral order) is like double-peaked. The candidates to the missing fibers are: 73, 74 77. 78 113. 114 117, 118 3277 A, B (c. 3) 3416 A (c.6) During the night, we collected ~ 15K dust-hour counts, so mirror has to be checked for dust. ---=== OBSERVING LOG ===--- Afternoon: ---------- spectro bias ok Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00061062.fit -6.1 -3.9 -2.8 1.7 7.1 9.1 10.4 sdR-b2-00061062.fit -8.5 -6.4 -4.8 1.5 7.1 9.1 10.8 sdR-r1-00061062.fit -7.5 -5.4 -3.5 1.5 6.6 8.5 10.5 sdR-r2-00061062.fit -7.6 -6.2 -4.5 0.8 6.4 8.1 9.5 cart. 5 is mounted Now the wind is from SWW, moderate dust count in the air, ~ 2500.

Temperature goes down a bit, a fewe C, humidity is rising. already 66%. We closed petels since guider can't guide with stars at this seeing any way. 07:45Z dust count reaches 3900, humidity ~68%, wind changed to SES, and we see more pollen in the air. Since there is no reason to stay open (seeing > 3" in the comparison with Marvels's 1.8" fiber). We closed the dome. 08:30Z situation is the same 09:30Z DIMM shows the same seeing around 3", with higher spikes. Dust count is still high, humidity is over 60%. 10:35Z seeing is still bad, we won't gain anything staying opened. We decide to call it a night. Fans off, louvers closed. 10:43Z endNight was manually finished. ---=== 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 61061, plate -9999 ------- 00:22 61061 0.0 bias 00:32 61062 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:37Z 5 3413 -30.90 -0.0042 73.26 0.0022 152.98 0.0035 1.000050 04:04Z 3 3277 227.39 0.0059 54.31 0.0053 76.78 0.0320 1.000140 05:13Z 6 3416 284.74 0.0022 43.49 0.0029 123.58 -0.0107 1.000030 06:21Z 3 3277 268.45 0.0047 53.31 0.0035 109.96 0.0184 0.999970 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 02:37Z 5 3413 1.00005 -493 567 -150 -31 73.3 15.7 19 182 -- 1.2" 04:04Z 3 3277 1.00014 -1381 -77 -100 227 54.3 15.0 10 184 -- 1.7" 05:13Z 6 3416 1.00003 -295 833 -125 285 43.5 15.7 19 206 -- 1.5" 06:21Z 3 3277 0.99997 296 1340 -75 268 53.3 15.1 10 213 -- 3.5" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 00:17Z 67 33 15 213 (SSW) 2357 - 00:47Z 65 33 16 203 (SSW) 2290 - clear 01:18Z 62 33 14 184 (S) 2321 - '' 01:48Z 59 33 14 209 (SSW) 2498 - '' 02:19Z 60 32 18 193 (SSW) 2769 - '' 02:52Z 59 31 17 188 (S) 2743 - '' 03:23Z 60 29 15 192 (SSW) 2923 - '' 03:54Z 61 26 15 194 (SSW) 2710 - '' 04:24Z 61 21 5 232 (SW) 2450 - '' 04:54Z 59 27 8 185 (S) 2338 - '' 05:25Z 60 25 21 209 (SSW) 2467 - '' 05:57Z 60 25 15 211 (SSW) 2534 - '' 06:28Z 58 29 16 204 (SSW) 2591 - '' 07:01Z 55 31 12 177 (S) 2835 - '' 07:31Z 50 39 14 175 (S) 3618 - '' 08:04Z 50 40 14 165 (SSE) 3996 - '' 08:35Z 52 38 15 167 (SSE) 3749 - '' 09:05Z 54 37 19 177 (S) 3526 - '' 09:37Z 53 40 19 180 (S) 3734 - '' 10:09Z 54 41 25 168 (SSE) 3926 - '' 10:41Z 53 40 18 193 (SSW) 3675 - '' ---=== TELESCOPE STATUS ===--- 00:45Z - Began ventilation.
