APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday March 16, 2008 (MJD 54542) ---=== OBSERVING TEAM ===--- Howard Brewington (dayShift) Viktor Malanushenko (observer) Elena Malanushenko (observer) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Neon lamp problem; see afternoon checkout. Telescope vibrations again today; see afternoon checkout. We did not open last night because clouds, high dust and humidity. ---=== OBSERVING LOG ===--- Afternoon: ---------- I talked with Dan and Wendell about a problem with the neon lamps, i.e., some of the lamps (#2, 3, and 4,) were not always working. Wendell asked that I power cycle the lamp's power supply by turning off the power switch for 30-seconds. When I turned the supply on again, all the lamps worked. During the checkout, while doing test slews, I noticed that the 2.5-meter telescope had a very bad vibration again when moved in Az and Rot with the following commands: scope position: 121,90,40 TCC> track 151, 90 mount /rota=00 /rotty=mount scope position: 151,90,00 TCC> track 121, 90 mount /rota=40 /rotty=mount The vibration occurred only when slews were done at the same time with Az and Rot. The vibration was greatest at the end of the slews. I also noticed that the vibrations were greater with the first track command listed above. Just FYI, the temp inside the enclosure was about 5.5-degrees C during my test slews. I talked with Dan about the vibration problems. The spectro focus was checked and slightly adjusted; it's set for about +2.0 degrees C. The per-adjusted spectro numbers via Collimate are posted in the Problems Section. The disk space at /data and /files was good; see below: Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 127G 7.9G 95% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 622G 249G 72% /data sdssfiles1:/data1/data 1.5T 545G 848G 40% /files iccSoundOff responded that all crates were available; see Problems Section for command's output. 23:15Z Because of very high winds and dust (15K), I did not open doors/louvers for turn on fans. Night: ------ We did not open because of the dust (28K), clouds, nearby radar return, but also there is no cartridge availble for observations until 4:35Z. We had some combination of weather problems for whole night. 10:00Z started ventilation, dust ~ 2.5K, humidity 75%, diff 4.0C, almost photometric. Cart 6 plate 2780 is mounted. The humidity dropped to 3.2 during for last 15 min, dust is 2.1K, seeing is 2.5", some clouds, north side radar return. 11:30Z Stopped ventilations adn closed. endNight is completed. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7370 22:38Z 22:55Z 100 O -136.37 -132.11 43 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 51097, plate -9999 ------- 22:38 51097 0.0 bias ----- sequence 51098, plate 2961 ------- 22:47 51098 10.0 flat 22:50 51099 2.0 arc 22:58 51100 3.0 arc 23:00 51101 3.0 arc 23:31 51102 2.0 arc 23:34 51103 3.0 arc ----- sequence 51104, plate -9999 ------- 00:37 51104 0.0 bias 00:41 51105 0.0 bias ----- sequence 51105, plate 2961 ------- 01:22 51106 3.0 arc 01:25 51107 3.0 arc 01:41 51108 10.0 flat 01:44 51109 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:34Z 50 10 40 209 (SSW) 12619 - 22:10Z 49 9 30 216 (SW) 12866 - 22:41Z 51 12 20 236 (SW) 23640 - 23:12Z 46 18 31 268 (W) 16144 - 23:43Z 42 18 27 262 (W) 14694 - 00:15Z 43 18 23 269 (W) 17725 - 00:47Z 41 17 19 247 (WSW) 20624 - 01:19Z 39 18 25 265 (W) 16871 - 01:51Z 38 19 22 253 (WSW) 17864 - 02:28Z 36 19 19 258 (WSW) 23945 - 03:00Z 35 19 19 258 (WSW) 26871 - 03:32Z 33 18 10 255 (WSW) 24140 - 04:04Z 32 17 22 241 (WSW) 14379 - 04:36Z 31 15 24 244 (WSW) 5646 - 05:08Z 30 15 15 250 (WSW) 5007 - 05:40Z 28 14 8 228 (SW) 3815 - 06:13Z 28 12 7 284 (WNW) 5605 - 06:45Z 28 13 6 269 (W) 4980 - 07:17Z 27 13 6 260 (W) 5831 - 07:49Z 26 16 7 294 (WNW) 3956 - 08:21Z 26 17 14 298 (WNW) 3005 - 08:53Z 24 16 9 288 (WNW) 2629 - 09:25Z 23 16 12 294 (WNW) 2498 - 09:58Z 22 15 12 264 (W) 2445 - 10:28Z 22 15 12 272 (W) 2194 - 10:58Z 21 15 11 276 (W) 2103 - 11:28Z 21 14 13 294 (WNW) 2018 - ---=== TELESCOPE STATUS ===--- 10:00Z Doors and louvers open, fans on.
