APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday July 5, 2008 (MJD 54653) ---=== OBSERVING TEAM ===--- Kaike Pan Audrey Simmons Dan Oravetz (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds on and off all night. We gained signal on: Cart 8, plate 2909 (most likely done - Brian Yanny will verify) Cart 7, plate 2563 Cart 6, plate 2320 (finished) We noticed both last night and tonight that the spectro dewer had trouble holding pressure. The tpm read the pressure around 3-8psi during a fill (the dewer itself read about 8-13psi), and it took forever to build back up when we turned on the pressure building valve. It seems to have this problem only when the lines are hooked up though. ---=== OBSERVING LOG ===--- Afternoon: ---------- Replaced the imager dewar with a fresh one. All systems checked and working properly. sdsshost2.apo.nmsu.edu % df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 134G 715M 100% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 646G 225G 75% /data sdssfiles1:/data1/data 1.5T 658G 735G 48% /files The 45-degree altitude fiducial was not read during the slew from 121,30,00 to 121,90,00. Spectro focus set for ~15 (sp1) and ~13 (sp2). Cartridge 3 is mounted. Night: ------ Clouds and nearby radar returns prevented us from opening at sunset. 03:20Z - Clouds thinned. We opened. 03:54Z - Mounted cart 8, segue179 plate 2909. GSFOGTF. 04:04Z - Precals. 04:10Z - 20 min exposure. Seeing 1.3" 04:33Z - 20 min exposure. 04:56Z - Postcals. We think this plate is done, but we will ask Brian Yanny his opinion before we will declare it as such. 05:06Z - Changed to cart 7, seguefaint 149 plate 2563. GSFOGTF. 05:17Z - Precals. 05:24Z - 20 min exposure. Seeing 1.7" 05:47Z - 25 min exposure. Seeing got progressively worse... ~2.5" 06:16Z - 25 min exposure. 06:41Z - Mid-cals. 06:49Z - 25 min exposure. Seeing better, 1.5", but now we have thick clouds. Read out after ~20 minutes since we lost all guide stars. We will wait until the clouds break. 07:43Z - Mid-cals. 08:01Z - Attempted to expose through a suckerhole, but had to abort it after 7 minutes since the clouds came back. 08:22Z - Another small break in the clouds. 25 min exposure started. Seeing 1.1" 08:50Z - 25 min exposure. Declared bad - too many clouds. 09:19Z - Postcals. This plate is not yet finished. 09:29Z - Mounted cart 6, seguefaint127 plate 2320. Too many clouds to see guide stars or an fk5 right away. 09:54Z - Precals. 10:00Z - 25 min exposure. Seeing 1.2" - lots of clouds, probably not good. 10:22Z - 20 min exposure. This plate is declared DONE. 10:50Z - Closed enclosure and stopped ventilating. 11:10Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7605 00:11Z 01:05Z 100 O -3.75 9.94 105 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 53945, plate 2901 ------- 01:10 53945 10.0 flat 01:13 53946 2.0 arc 01:16 53947 3.0 arc 01:18 53948 3.0 arc ----- sequence 53949, plate -9999 ------- 01:39 53949 0.0 bias ----- sequence 53950, plate -9999 ------- 01:44 53950 0.0 bias ----- sequence 53951, plate 2909 ------- 04:06 53951 10.0 flat 04:09 53952 2.0 arc 04:32 53953 1201.0 target 04:55 53954 1202.0 target 04:58 53955 10.0 flat 05:01 53956 2.0 arc ----- sequence 53957, plate 2563 ------- 05:19 53957 10.0 flat 05:22 53958 2.0 arc 05:46 53959 1201.0 target 06:14 53960 1501.0 target 06:42 53961 1500.0 target 06:45 53962 10.0 flat 06:48 53963 2.0 arc 07:10 53964 1139.0 target 07:45 53965 10.0 flat 07:48 53966 2.0 arc 08:50 53967 1500.0 target 09:17 53968 1500.0 target 09:22 53969 10.0 flat 09:24 53970 2.0 arc ----- sequence 53971, plate 2320 ------- 09:57 53971 10.0 flat 09:59 53972 2.0 arc 10:21 53973 1096.0 target 10:44 53974 1200.0 target 10:47 53975 10.0 flat 10:49 53976 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 04:17Z 8 2909 -35.33 0.0005 51.72 0.0040 150.85 0.0074 1.000160 05:31Z 7 2563 156.44 0.0034 54.60 0.0037 -47.03 0.0041 1.000260 06:30Z 7 2563 166.55 0.0034 58.65 0.0037 -25.24 0.0041 1.000240 07:09Z 7 2563 174.80 0.0034 59.96 0.0037 -9.63 0.0041 1.000210 08:32Z 7 2563 193.38 0.0030 58.65 0.0036 24.97 0.0182 1.000220 10:11Z 6 2320 -17.00 -0.0006 48.72 0.0046 165.60 0.0182 1.000410 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:48Z 3 0 1.00000 0 1257 0 121 30.0 17.7 2 176 - ... 04:17Z 8 2909 1.00016 -1580 -242 -110 -35 51.7 15.0 16 126 - 1.3 05:30Z 7 2563 1.00026 -2568 -1008 -50 156 54.6 14.4 13 135 - 1.7 06:30Z 7 2563 1.00024 -2370 -861 -55 167 58.6 13.7 2 179 - 2.5 07:09Z 7 2563 1.00021 -2074 -704 -140 175 60.0 15.4 9 193 - 1.5 08:32Z 7 2563 1.00022 -2173 -783 -140 193 58.7 15.3 9 200 - 1.1 10:11Z 6 2320 1.00041 -4049 -2286 -120 -17 48.7 14.6 13 195 - 1.2 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 01:02Z 64 40 4 158 (SSE) 1161 - cloudy 01:33Z 63 41 5 184 (S) 1239 - cloudy 01:53Z 63 41 8 169 (S) 1306 - " 02:25Z 62 43 7 150 (SSE) 1573 - " 02:57Z 61 44 14 137 (SE) 1632 - " 03:27Z 60 44 14 143 (SE) 1697 - " 03:57Z 59 46 15 133 (SE) 1945 - partly cloudy 04:27Z 58 47 17 125 (SE) 2331 - " 04:58Z 58 46 18 129 (SE) 2350 - clear 05:28Z 58 46 10 139 (SE) 2381 - " 05:58Z 57 45 6 160 (SSE) 2260 - " 06:28Z 56 45 4 182 (S) 2303 - " 06:58Z 59 44 7 216 (SW) 1914 - very cloudy 07:28Z 59 45 6 189 (S) 1943 - " 08:01Z 58 45 9 202 (SSW) 1719 - " 08:32Z 59 45 8 193 (SSW) 1653 - " 09:03Z 58 45 9 208 (SSW) 1743 - " 09:33Z 58 45 7 198 (SSW) 1680 - " 10:03Z 58 46 9 198 (SSW) 1747 - " 10:33Z 57 47 9 190 (S) 1863 - partly cloudy 11:06Z 56 48 10 180 (S) 1712 - " ---=== TELESCOPE STATUS ===--- 03:30Z - Began ventilation.
