The wind and dust died down by 0410Z but clouds kept us closed until 0830Z. Still, we finished one plate (921) and got good data on another plate (817). The spectrograph focus checked out ok. All sigma values were in the black for the first plate but 2 were in the yellow for the second plate. At the end of the night the bellows vacuum pressure was reading 13 instead of 17. We switched over from the venturi pump to the mechanical pump and French was notified. ---=== OBSERVING LOG ===--- Afternoon checkout (from Steph) ------------------------------- A small amount of glycol/water mix was found under the reservoir in the SE corner of the lower enclosure (for the lamps). French was notified. The spectrograph focus checked out ok. The numbers can be found in the Problems section. (Sorry Robert.) PT motors were well-behaved during checkout. The laptop sirrobert was in a catatonic state, blankly staring off into space when I went to the enclosure (this was before rebooting sdsshost). I checked all the connections and all was well. The only fix I found that worked was to reboot the laptop. Night activities ---------------- Clouds, dust and wind delayed opening until 08:30Z. Partly cloudy upon opening so we go with spectroscopy. Plate 921 (cartridge 4): 2 guide stars on the gotoField (with last night's offsets). Had to chase the focus and seeing was variable. Finished in 3 exposures. Plate 817 (cartridge 1): After previous offsets were cleared, guide stars appeared. We obtained one good exposure before twilight arrived. Most xsigma and wsigma values were in the black but some yellow values started to appear towards the end of the night (cartridge 1, plate 817). At the end of the night the bellows vacuum pressure was reading 13 instead of 17. We switched over from the venturi pump to the mechanical pump and French was notified. No other problems tonight. ---=== 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 --------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields nGood rowMean rowSig colMean colSig rot --------------------------------------------------------------- ---=== SPECTROSCOPY DATA SUMMARY ===--- UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 14603, plate -9999 ------- 00:34 14603 0.0 bias ----- sequence 14604, plate 904 ------- 00:39 14604 0.0 bias ----- sequence 14605, plate -9999 ------- 04:18 14605 0.0 bias ----- sequence 14606, plate 921 ------- 16.1 13.5 15.7 15.6 DONE 09:07 14606 10.0 flat 09:09 14607 2.0 arc 09:29 14608 900.0 target 09:57 14609 1503.0 target 10:30 14610 1503.0 target 10:37 14611 240.0 smear 10:40 14612 10.0 flat 10:42 14613 2.0 arc ----- sequence 14614, plate 817 ------- 6.9 6.2 8.4 8.1 11:02 14614 10.0 flat 11:04 14615 2.0 arc 11:28 14616 1201.0 target 11:35 14617 240.0 smear ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 09:14Z 4 921 -22.66 0.0012 53.00 0.0016 161.03 -0.0223 1.000210 10:28Z 4 921 -47.39 0.0012 43.96 0.0016 141.68 -0.0223 1.000120 11:10Z 1 817 237.08 0.0007 74.23 -0.0002 67.44 -0.0063 1.000210 11:17Z 1 817 238.75 0.0007 73.02 -0.0002 70.14 -0.0063 1.000140 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL5258 Stays: JL5265 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 09:13Z 4 921 1.00021 -2073 -176 370 -22 53.1 4.4 13 272 ---- 2.0 10:19Z 4 921 1.00019 -1875 -117 240 -45 45.4 3.1 14 289 ---- 2.2 11:10Z 1 817 1.00021 -2073 -462 130 237 74.3 3.0 14 268 ---- 2.6 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:44Z 54 19 26 215 (SW) 3032 - mcl 00:16Z 53 19 20 218 (SW) 4362 - mcl 00:48Z 53 23 16 240 (WSW) 4206 - mcl 01:20Z 52 20 22 254 (WSW) 3957 - mcl 01:52Z 50 17 23 218 (SW) 6612 - mcl 02:22Z 50 12 32 223 (SW) 4698 - mcl 02:53Z 49 13 27 222 (SW) 7154 - mcl 03:23Z 49 14 17 263 (W) 6791 - mcl 03:54Z 49 16 18 251 (WSW) 1680 - mcl 04:24Z 48 15 20 259 (W) 1386 - mcl 04:54Z 47 14 17 267 (W) 1192 - mcl 05:24Z 46 14 14 265 (W) 996 - mcl 05:54Z 45 17 16 283 (WNW) 955 - mcl 06:24Z 44 19 18 273 (W) 957 - mcl 06:55Z 44 18 14 266 (W) 892 - mcl 07:25Z 43 19 16 264 (W) 892 - mcl 07:55Z 42 20 15 255 (WSW) 954 - pcl 08:25Z 40 18 15 256 (WSW) 1151 - pcl 08:56Z 40 22 15 267 (W) 1119 - clear 09:28Z 39 24 13 266 (W) 1229 - clear 09:59Z 37 26 14 285 (WNW) 1302 - clear 10:30Z 37 27 13 270 (W) 1283 - clear 11:02Z 37 27 15 282 (WNW) 1356 - clear 11:35Z 37 26 10 269 (W) 1333 - clear 12:07Z 36 24 17 269 (W) 1099 - clear ---=== TELESCOPE STATUS ===--- 08:30 Doors open, fans on 08:30 Enclosure off 11:40 Enclosure on, doors closed, fans off.
