APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday June 24, 2009 (MJD 55007) ---=== OBSERVING TEAM ===--- Audrey Simmons Kaike Pan ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The first 1.8 and last 2.0 hours was lost to clouds. We opened at 5:20Z, and finished one plate: 3459, added signals on another: 3478. ---=== OBSERVING LOG ===--- Afternoon: ---------- Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 119G 16G 89% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 777G 94G 90% /data sdssfiles1p:/data1/data 1.5T 608G 786G 44% /files No problems during checkout. Checked collimators and left them set for a temperature of ~13C. Did not start ventilating because of threatening rain clouds. Night: ------ 01:20Z Humidity at 72% and sky looked promising, we started ventilation. 02:20Z nearby radar return and threaten clouds delayed open. 03:00Z overcast, decided not to open. 05:00Z enclosure off. 05:10Z mount cartridge 1, fill spectro dewars. 05:35Z cart 1, plate 3459 (SEGUE2). SOGTF. 05:40Z precalib. 05:49Z started the 1st science exposure. The plate was done with One exposure combines with four exposures took on mjd 55004. --------------------------------------------------- MJD b1 r1 b2 r2 Texp Sum --------------------------------------------------- 55004 8.0 5.5 10.3 7.3 1800.0 31.1 55004 7.9 6.1 10.5 8.7 1800.0 33.2 55004 7.2 5.6 9.6 7.3 1800.0 29.7 55004 4.0 3.9 6.5 6.6 1307.0 21.0 55007 11.2 7.6 14.5 11.7 1500.0 45.0 --------------------------------------------------- Total: 38.3 28.7 51.4 41.6 8207.0 --> 160.0 Total when ALL b,r values > 2.0: 38.3 28.7 51.4 41.6 8207.0 --> 160.0 (limit=156.5) 06:36Z cart 8, plate 3489. FK5 used to acquire the field. Sorry, we mount this marvels plate by mistake. 20 minutes was lost. Cartridge 4 and 8 are Marvels plates, and still show up in the database. We unloaded them from the database. 06:55Z cart 5, plate 3478 (SEGUE). SOGTF. Partly cloudy with 1.5" seeing. The third exposure was aborted due to clouds. Got two good exposures on this plate. 08:30Z close FFS, wait sky improvement. 10:10ZSky did not improve we decided to call it night. 10:25Z endNight rejoiced. ---=== 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): y QA Procedures Done (y/n): y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 61934, plate -9999 ------- 00:35 61934 0.0 bias ----- sequence 61935, plate 3395 ------- 00:40 61935 10.0 flat 00:42 61936 2.0 arc 00:45 61937 3.0 arc 00:48 61938 3.0 arc ----- sequence 61939, plate -9999 ------- 01:05 61939 0.0 bias ----- sequence 61940, plate 3459 ------- 05:44 61940 10.0 flat 05:46 61941 2.0 arc 06:15 61942 1500.0 target 06:24 61943 10.0 flat 06:27 61944 2.0 arc ----- sequence 61945, plate 3489 ------- 06:45 61945 10.0 flat 06:47 61946 2.0 arc 06:51 61947 10.0 flat 06:53 61948 2.0 arc ----- sequence 61949, plate 3478 ------- 07:08 61949 10.0 flat 07:10 61950 2.0 arc 07:44 61951 1500.0 target 08:17 61952 1801.0 target 08:27 61953 483.0 target 08:30 61954 10.0 flat 08:33 61955 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 05:49Z 1 3459 -82.23 -0.0105 81.09 0.0052 103.19 0.0325 1.000160 07:17Z 5 3478 252.52 -0.0030 60.12 0.0028 93.56 0.0004 1.000150 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 05:49Z 1 3459 1.00016 -1579 -265 -75 -82 81.0 14.8 13 115 -- 1.2 07:17Z 5 3478 1.00015 -1480 -9 65 253 60.1 13.4 18 125 -- 1.5 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 00:29Z 59 48 10 143 (SE) 1371 - 01:00Z 58 50 11 128 (SE) 1420 - cloudy 01:42Z 57 50 10 129 (SE) 1420 - 02:14Z 59 48 10 140 (SE) 1408 - 02:45Z 57 48 10 125 (SE) 1305 - 03:19Z 59 46 10 127 (SE) 1253 - 03:49Z 59 45 10 132 (SE) 1142 - 04:19Z 59 46 13 131 (SE) 1242 - 04:51Z 60 46 13 142 (SE) 1148 - cloudyy 05:23Z 60 47 12 139 (SE) 1147 - partly cloudy 05:55Z 58 47 12 108 (ESE) 1199 - 06:28Z 57 47 14 116 (ESE) 1213 - 06:59Z 57 47 14 123 (ESE) 1444 - 07:32Z 56 46 12 112 (ESE) 1473 - 08:02Z 57 46 12 123 (ESE) 1465 - 08:33Z 57 45 12 114 (ESE) 1460 - cloudy 09:06Z 58 45 11 108 (ESE) 1369 - 09:36Z 58 45 12 109 (ESE) 1354 - 10:06Z 58 45 10 108 (ESE) 1369 - cloudy ---=== TELESCOPE STATUS ===--- 01:20Z - Began ventilation.
