APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday June 1, 2003 (MJD 52792) ---=== OBSERVING TEAM ===--- Wimpy & Grumpy (Nitta & Harvanek, respectively) visitors: Krzesinski, Brewington and other gourmets un-invited guests: billions of moths, clouds ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Most of the night spent trying to dodge the clouds without a lot of success. One plate finished (1344) and good data for another 3 plates (1314, 1323, 1342). Multiple windscreen touches tonight. Gourmet chow. ---=== OBSERVING LOG ===--- Afternoon: Spectros were refocused. Piston values are in the PROBLEM section. Night: Partly cloudy at sunset so we begin with spectroscopy. Windscreen touch while preparing to open: altitude (Windscreen touched in altitude: DOWN (2003-06-02 02:12:10Z sdssmcp): 2003-06-02 02:12:16Z) Plate 1344 (cartridge 5): Guide stars on the gotoField. When combined with last night's data (52791), this plate was finished in a single 900 sec exposure. Another 600 sec exposure was taken while waiting for the SoS results from the first exposure. However, due to clouds, the (S/N)^2 was < 2 for all cameras for this exposure and so it was declared bad. Plate 1314 (cartridge 6): Guide stars on the gotoField. The first exposure was lost to clouds and was declared bad. We waited for a while for heavy clouds to thin. The second exposure (900 sec) was good. The plate expired before we could complete it. Plate 1323 (cartridge 9): Guide stars on the gotoField. The first exposure was aborted after being paused for clouds for too long. The second exposure (1800 sec) was good. The plate expired before we could complete it. Plate 1354 (cartridge 7): Guide stars on the gotoField. We attempted one exposure but it was lost to clouds. We then closed due to threatening clouds. By the time we reopened, the plate was near expiration so we changed cartridges. Windscreen touch while preparing to close: altitude (Windscreen touched in altitude: UP (2003-06-02 08:06:52Z sdssmcp): 2003-06-02 08:07:04Z) Windscreen touch while preparing to open: altitude (Windscreen touched in altitude: UP (2003-06-02 09:16:34Z sdssmcp): 2003-06-02 09:16:38Z) Plate 1342 (cartridge 4): Guide stars on the gotoField. One good exposure (1500 sec) before twilight. Windscreen touch while preparing to close: altitude (Windscreen touched in altitude: UP (2003-06-02 10:43:31Z sdssmcp): 2003-06-02 10:43:36Z) endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 3976 23:57Z 00:16Z 100 O -41.33 -36.65 45 ignore ---=== 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): YES QA Procedures Done (y/n): YES UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 21235, plate 1344 ------- 7.4 7.8 7.1 7.5 tonight 00:12 21235 10.0 flat test 8.5 8.2 7.3 6.5 52791 00:15 21236 2.1 arc " ------------------- 00:18 21237 2.1 arc " 15.9 16.0 14.4 14.0 DONE 00:32 21238 2.1 arc " 00:35 21239 2.1 arc " 03:24 21240 10.0 flat 03:26 21241 2.0 arc 03:50 21242 900.1 target 04:03 21243 600.1 target bad (clouds) ----- sequence 21244, plate 1314 ------- 3.1 2.6 2.9 2.5 04:18 21244 10.0 flat 04:20 21245 2.0 arc 04:56 21246 661.8 target bad (clouds) 05:55 21247 900.1 target ----- sequence 21248, plate 1323 ------- 8.2 7.7 8.8 6.1 06:10 21248 10.0 flat 06:13 21249 2.0 arc 07:24 21250 1800.1 target ----- sequence 21251, plate 1354 ------- no good data 07:37 21251 10.0 flat 07:39 21252 2.0 arc 08:02 21253 612.6 target bad (clouds) ----- sequence 21254, plate 1342 ------- 6.8 7.9 6.6 6.4 09:33 21254 10.0 flat 09:36 21255 2.0 arc 10:29 21256 1500.1 target 10:37 21257 240.0 smear ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 03:37Z 5 1344 161.66 0.0038 78.60 0.0039 -21.43 -0.0103 1.000040 04:28Z 6 1314 210.07 0.0026 58.25 0.0034 51.53 -0.0094 1.000180 06:18Z 9 1323 214.28 0.0044 59.23 0.0039 55.88 0.0006 1.000180 07:46Z 7 1354 256.89 0.0057 64.95 0.0028 93.83 -0.0127 1.000090 09:50Z 4 1342 263.80 0.0041 55.42 0.0018 105.43 -0.0079 1.000090 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL6477 Stays: JL6478 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 03:37Z 5 1344 1.00004 -394 493 -300 162 78.6 16.5 8 10 ---- 1.8" 04:28Z 6 1314 1.00018 -1776 -590 -275 210 58.3 16.4 6 350 ---- 1.8" 06:17Z 9 1323 1.00018 -1776 -617 -300 214 59.3 15.9 6 3 ---- 1.8" 07:45Z 7 1354 1.00009 -888 105 -300 257 65.0 15.9 8 31 ---- 1.8" 10:01Z 4 1342 1.00009 -888 135 -300 263 53.1 15.6 12 10 ---- 1.8" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:59Z 69 24 12 262 (W) 618 - pcl 00:31Z 70 26 19 256 (WSW) 716 - " 01:03Z 68 21 16 286 (WNW) 534 - " 01:35Z 65 28 6 287 (WNW) 1906 - " 02:07Z 62 31 7 22 (NNE) 724 - " 02:43Z 61 32 15 14 (NNE) 583 - " 03:16Z 60 31 11 31 (NNE) 600 - " 03:48Z 61 31 9 359 (NNW) 724 - " 04:21Z 61 31 11 358 (NNW) 754 - " 04:53Z 61 31 8 341 (NNW) 783 - mcl 05:25Z 61 31 8 354 (NNW) 850 - " 05:56Z 61 31 11 6 (N) 911 - pcl 06:26Z 60 31 9 5 (N) 770 - " 06:58Z 61 33 8 4 (N) 852 - " 07:30Z 60 33 3 10 (N) 766 - " 08:01Z 60 33 9 28 (NNE) 798 - " 08:33Z 59 33 8 36 (NE) 802 - " 09:05Z 60 32 6 20 (NNE) 698 - " 09:37Z 60 33 10 17 (NNE) 822 - " 10:07Z 59 33 5 3 (N) 833 - " 10:37Z 60 33 10 29 (NNE) 811 - " 11:07Z 60 33 9 26 (NNE) 797 - " ---=== TELESCOPE STATUS ===--- 02:10Z Enclosure doors opened, fans and blowers on, louvers opened. 02:15Z Enclosure off. 08:15Z Enclosure on (threatening clouds). 09:20Z Enclosure off. 10:45Z Enclosure on, doors closed, fans and blowers off, louvers closed.
