APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday April 15, 2007 (MJD 54206) ---=== OBSERVING TEAM ===--- Shannon Watters Dan Oravetz Demitry Bizyaev (visitor) Elena Malanushenko (day) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Spectroscopy and wind. The sky was clear all night, but high winds kept us closed for a few hours. Finished Cartridge 3, plate 2550, segue148 with 1X20-minute exposure. Finished Cartridge 9, plate 2137, chunk109 with 1X20, 1X10, and 1X15-minute exposures. Got good signal on Cartridge 5, plate 2162, chunk112 with 1X15 and 1X25-minute exposures. Misc. Watcher errors in the Problems section. ---=== OBSERVING LOG ===--- Afternoon: --------- The telescope has been checked and prepared for observations and all systems are functioning properly. There is an alarm (red blinks and bipping) on circulation panel, probably the settings of block has to be adjusted to warm outside temperature. We need help to do it. The collimation is set for 5.5C using median mechSend temperature. 00:30Z - Began ventilation. Doors and louvers open, fans on. Night: ----- 01:37Z - Enclosure off. Opened to clear skies, but high wind and poor seeing. 02:40Z - Cartridge 1, plate 2409, seguefaint134. Needed an FK5 to acquire the field because of sky brightness (we started a little bit early to get the focus and offsets all set to go). Pre-calib. 1X15-minute exposure (declared bad: (S/N)^2 < 2.0 in b1 and r1). 1X25-minute exposure (rejected by SoS, see below). SoS gave the following warnings: sdR-r1-00044246.fit: ABORT: Reject science: Flat-field screens are closed! sdR-r1-00044246.fit: ABORT: Unable to reduce science exposure sdR-b1-00044246.fit: ABORT: Reject science: Flat-field screens are closed! sdR-b1-00044246.fit: ABORT: Unable to reduce science exposure sdR-r2-00044246.fit: ABORT: Reject science: Flat-field screens are closed! sdR-r2-00044246.fit: ABORT: Unable to reduce science exposure sdR-b2-00044246.fit: ABORT: Reject science: Flat-field screens are closed! sdR-b2-00044246.fit: ABORT: Unable to reduce science exposure Seeing: 2.3" - 3.0". 03:47Z - Enclosure on for high wind. 08:10Z - Enclosure off. 08:21Z - Cartridge 3, plate 2550, segue148. Needed an FK5 to acquire the field. Pre-calib. 1X20-minute exposure. Post-calib. Seeing: 1.5" - 2.2". SoS warned of a whopping fiber and bad sky residuals. Plate declared done. 09:15Z - Cartridge 9, plate 2137, chunk109. Guide stars on the gotoField. Pre-calib. 1X20-minute exposure; 1X10-minute exposure; 1X15-minute exposure. Seeing: 1.7" - 2.1". SoS gave no warnings. Plate declared done. 10:22Z - Cartridge 5, plate 2162, chunk112. Guide stars on the gotoField. Pre-calib. 1X15-minute exposure; 1X25-minute exposure. Seeing: 1.8" - 2.0". SoS gave a max sky-residual chi2 warning. 11:34Z - Enclosure on. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6784 21:48Z 22:10Z 100 O -120.08 -114.63 50 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; bias (44234), flat (44252), arc (44253), science plate 2550 (44249), science plate 2137 (44256), science plate 2162 (44259) UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 44234, plate -9999 ------- 22:05 44234 0.0 bias ----- sequence 44235, plate 2550 ------- 22:17 44235 10.0 flat 22:20 44236 2.0 arc 22:32 44237 3.0 arc 22:34 44238 2.0 arc 23:03 44239 3.0 arc 23:05 44240 3.0 arc 01:14 44241 0.0 bias 01:21 44242 0.0 bias ----- sequence 44243, plate 2409 ------- 02:43 44243 10.0 flat 02:45 44244 2.0 arc 03:05 44245 900.0 target 03:34 44246 1503.0 target ----- sequence 44247, plate 2550 ------- 08:26 44247 10.0 flat 08:28 44248 2.0 arc 08:54 44249 1202.0 target 08:57 44250 10.0 flat 08:59 44251 2.0 arc ----- sequence 44252, plate 2137 ------- 09:20 44252 10.0 flat 09:22 44253 2.0 arc 09:46 44254 1200.0 target 09:59 44255 602.0 target 10:17 44256 902.0 target ----- sequence 44257, plate 2162 ------- 10:31 44257 10.0 flat 10:34 44258 2.0 arc 10:52 44259 900.0 target 11:21 44260 1501.0 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:34Z 1 2409 41.33 0.0017 49.32 0.0019 213.68 -0.0099 1.000250 08:22Z 3 2550 160.91 0.0018 56.56 0.0006 -37.10 -0.0122 1.000210 09:25Z 9 2137 281.32 0.0016 71.85 0.0012 111.47 0.0071 1.000220 11:08Z 5 2162 282.46 -0.0001 59.18 -0.0006 117.71 -0.0210 1.000030 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 02:34Z 1 2409 1.00025 -2469 -860 0 41 49.3 8.0 25 127 ---- 2.3" 08:22Z 3 2550 1.00021 -2074 -505 50 161 56.6 6.0 21 176 ---- 1.8" 09:24Z 9 2137 1.00022 -2173 -470 200 281 71.9 5.5 17 159 ---- 1.8" 10:36Z 5 2162 1.00001 -99 1207 150 291 65.8 5.0 17 160 ---- 1.8" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 00:05Z 51 10 24 151 (SSE) 1098 - Clear 00:38Z 49 6 33 136 (SE) 1066 - Clear 01:10Z 48 7 26 141 (SE) 1053 - Clear Watcher:Weather:Wind - gusts (36.5 (high) occurred repeatedly) 01:43Z 47 8 25 156 (SSE) 1021 - Clear 02:15Z 46 7 20 123 (ESE) 931 - Clear 02:46Z 46 9 30 123 (ESE) 890 - Clear Watcher:Weather:Wind - winds (38.7 (high) occurred repeatedly) 03:16Z 45 8 38 138 (SE) 956 - Clear 03:47Z 45 8 33 145 (SE) 957 - Clear 04:19Z 44 9 25 149 (SSE) 912 - Clear 04:51Z 44 10 23 136 (SE) 848 - Clear 05:24Z 47 12 14 176 (S) 1065 - Clear 05:56Z 48 13 24 164 (SSE) 1254 - Clear 06:29Z 46 13 23 175 (S) 1047 - Clear 07:00Z 45 10 22 162 (SSE) 927 - Clear 07:32Z 45 13 21 192 (SSW) 1065 - Clear 08:04Z 43 13 21 160 (SSE) 1025 - Clear 08:37Z 42 14 18 160 (SSE) 866 - Clear 09:08Z 41 14 15 162 (SSE) 1036 - Clear 09:39Z 43 14 15 175 (S) 902 - Clear 10:09Z 41 14 17 153 (SSE) 947 - Clear 10:41Z 41 14 15 165 (SSE) 976 - Clear 11:13Z 41 14 16 156 (SSE) 1146 - Clear ---=== TELESCOPE STATUS ===--- 00:30Z - Began ventilation.
