APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday May 11, 2010 (MJD 55328) ---=== OBSERVING TEAM ===--- Howard Brewington Steph Snedden ---=== OBSERVING PLAN ===--- Civil Date MJD Lunar UT Twilight ST Twilight (evening) (18:00) Phase Even Morn Even Morn Observing Program 11 May 2010 55328.0 0.12 03:26 10:33 11:42 18:50 BOSS 7.1 hours ---=== OBSERVING SUMMARY ===--- We observed the following BOSS plates: Cartridge Plate Done? ----------------------- 10 4006 DONE 13 4023 DONE 12 3938 DONE 17 3928 not done We accumulated about 50,000 particles/ft^3 of dust over the night. The mirrors should probably be checked. Note that we tried choosing plates for plugging from the Platedb web interface, and compared with Kyle's list. There are many plates in Kyle's list that are still in "design" phase. Also, we found a discrepancy in priority for plate 3986 (priority 2 in the web interface, priority 7 in Kyle's list). Another rotator abort in mid-slew caused a delay. Details in the log. ---=== OBSERVING LOG ===--- Afternoon: ---------- 23:30Z Started the checkout. 23:35Z Restarted the Watcher servers. 23:40Z Mounted the first cart of the night. 23:45Z Checked that the plates are in data base with 'platedb showActive' 23:50Z Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 130G 4.5G 97% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 844G 28G 97% /data sdssfiles1p:/data1/data 1.8T 123G 1.7T 7% /files 23:51Z Verified that the STUI actors were happy. 00:10Z Spectro focus was checked and adjusted with scope at 121,90,00 Pre-adjusted collimate numbers are posted in the Problem Section.

Cartridge 12, plate 3938 ======================== In mid slew, the rotator aborted. After the rotator was cleared, the azimuth axis aborted. We had to do "gotoField abort" and wait for the timeout, then started again. Just three minutes were lost, but then we had no guide stars. There were large errors on azimuth. After forcing the correction, we went back to the field. At that point, sop was unresponsive and we needed a sop restart and had to wait for sop to become responsive again. All told, we lost 35 minutes to all these problems. ---- logfile-55328.html ---- ------------------------------------------------------------ MJD b1 r1 b2 r2 Texp Sum Plugfile ------------------------------------------------------------ 55328 3.5 7.1 4.2 8.0 900.8 22.8 3938-55326-01 1.2" FWHM 55328 3.5 6.7 4.1 7.5 900.8 21.8 3938-55326-01 55328 3.4 6.7 3.8 7.5 900.8 21.4 3938-55326-01 55328 3.3 6.3 3.7 6.8 900.8 20.1 3938-55326-01 ------------------------------------------------------------ 13.7 26.8 15.8 29.8 3603.2 --> 86.1 ------------------------------------------------------------ This plate is DONE Cartridge 17, plate 3928 ======================== 10:08Z - GSOGTF ---- logfile-55328.html ---- ------------------------------------------------------------ MJD b1 r1 b2 r2 Texp Sum Plugfile ------------------------------------------------------------ 55328 2.8 8.5 2.6 5.2 900.8 19.1 3928-55328-01 1.2"FWHM 55328 2.4 7.6 2.2 4.6 900.8 16.8 3928-55328-01 ------------------------------------------------------------ 5.2 16.1 4.8 9.8 1801.6 --> 35.9 ------------------------------------------------------------ Not done yet ---=== TELESCOPE OFFSETS AND SCALE I ===--- 05:55Z Cart 13 CurrArcOff = -0.002010, 0.000000, 4780360683.49000, 0.001063, 0.000000, 4780360683.49000 09:23Z Cart 12 CurrArcOff = 0.000646, 0.000000, 4780373233.17000, 0.000783, 0.000000, 4780373233.17000 ---=== FOCUS LOG ===--- 09:25Z Cart 12 1.00024 -2369 -355 450 -71 58.2 6.5 19 242 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:39Z 59 7 40 217 (SW) 5685 - mostly clear 00:11Z 59 10 35 226 (SW) 5055 - ' 00:43Z 57 10 25 258 (WSW) 4281 - ' 00:59Z 57 12 32 264 (W) 4462 - ' 01:31Z 54 12 22 256 (WSW) 4195 - ' 02:03Z 53 11 28 252 (WSW) 4098 - ' 02:35Z 52 12 25 253 (WSW) 3715 - ' 03:08Z 52 11 27 232 (SW) 3948 - ' 03:40Z 52 11 20 211 (SSW) 3583 - ' 04:12Z 52 9 34 226 (SW) 4425 - partly cloudy 04:44Z 51 10 33 225 (SW) 4599 - ' 05:16Z 51 10 28 231 (SW) 3777 - ' 05:48Z 49 10 22 223 (SW) 3842 - ' 06:20Z 47 10 21 236 (SW) 3730 - ' 06:53Z 48 9 25 229 (SW) 3351 - mostly clear 07:25Z 46 8 17 236 (SW) 3239 - ' 07:57Z 45 9 18 232 (SW) 3370 - ' 08:29Z 44 10 19 239 (WSW) 2949 - ' 09:01Z 44 11 21 234 (SW) 2812 - ' 09:33Z 43 11 16 244 (WSW) 2870 - ' 10:06Z 43 13 18 232 (SW) 2437 - ' 10:38Z 42 14 17 240 (WSW) 2569 - ' ---=== TELESCOPE STATUS ===--- 02:30Z Doors and louvers opened, fans on. 02:45Z Enclosure off. 10:55Z Enclosure on, doors and louvers closed, fans off.
