APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday September 26, 2009 (MJD 55101) ---=== OBSERVING TEAM ===--- Howard Brewington Dmitry Bizyaev ---=== OBSERVING PLAN ===--- MARVELS science forst half of the night then either BOSS imaging or tests with BOSS-sp cartridges ---=== OBSERVING SUMMARY ===--- Sp2 took a long time to fill in the evening (~ half an hour) Exposed MARVELS plates: 3490 B (c. 3) 3518 A (c. 4) 3518 B (c. 4) - missed fibers 101, 102 3513 A (c. 9) Guider tested on plate 3513 B - works fine. Imaging: stripe 75 S between lambdas 143 and 162, including ramps, run 8060 stripe 81 N between lambdas -168 and, including ramps, run 8062 Imager bias We mounted cart. 11 - BOSS, adjusted collimation, got guide stars, and night gets over at this point (30 min past twilight). Note that hartmann+adjustment+hartmann took us more than 46 min (3 runs until it gets collimated), not counting suggested blue ring move (takes much longer cause we have to do trip to telescope for it). Power outage at 3 am, because of planned works. We lost ~ 50 min of photometric night time because the outage affected the telescope. Formally this is 50 min, but we are unable to do one more stripe this night: we did everything fast, but still had a lack of 12 minutes to fulfill the "100 science frames" requirement till "twilight+4 min". So, actually, we spent the 3+ hours of photometic conditions to cover the 2-degrees gap in stripe 81 N. Expensive :( Site is on generator power from 09:00Z to ~ 12Z. ---=== OBSERVING LOG ===--- Afternoon: ---------- 22:30Z Started the afternoon checkout. 22:35Z Restarted the servers. 22:40Z Did quick check of mirror numbers. 22:45Z Started the imager bias. 22:46Z Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 128G 7.5G 95% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 818G 53G 94% /data sdssfiles1p:/data1/data 1.8T 113G 1.7T 7% /files hub25mp:/home 92G 53G 40G 57% /home_hub25m 22:56Z Turned on MARVELS ThAr lamp 23:10Z Verified that the STUI actors were happy; also checked the status of the hub25m and perms. 23:18Z Started the collimation check for BOSS spectros.

Telescope moved to the same direction as yesterday (~6" negative in DEC) and we got one g. star! It took us ~25 min to find guide stars with this cartridge: there are only 3 guide fibers usable, with no large fibers available. -- calibration: File Exptime IMGAVG Exptype MARVELS1.2009-09-27T01:35:42.110.fits[0] 11.000000 46150.089844 5417.194824 TIO MARVELS1.2009-09-27T01:37:47.490.fits[0] 160.000000 320.075012 734.677734 THAR MARVELS1.2009-09-27T01:42:22.030.fits[0] 11.000000 47028.183594 5418.978027 TIO 02:22Z science 50 min, plate 3490 B, K7, T02:22:06.510.fits =37.0 T02:22:06.510.fits -- calibration: MARVELS1.2009-09-27T03:14:03.150.fits[0] 11.000000 48304.183594 5408.198242 TIO MARVELS1.2009-09-27T03:16:08.450.fits[0] 160.000000 319.825012 734.665833 THAR MARVELS1.2009-09-27T03:20:43.960.fits[0] 11.000000 44702.183594 5399.662109 TIO -- gotoFiend with cart. 4 plate 3518 A 03:24Z science 50 min, plate 3518 A, KEPLER4, T03:24:09.070.fits =37 -- calibration: MARVELS1.2009-09-27T04:16:19.440.fits[0] 11.000000 48322.726562 5407.737305 TIO MARVELS1.2009-09-27T04:18:23.600.fits[0] 160.000000 317.662506 734.622070 THAR MARVELS1.2009-09-27T04:22:58.190.fits[0] 11.000000 45323.816406 5396.415527 TIO -- 04:15Z gotoFiend with cart. 4 plate 3518 B GSOGTF 04:25Z science 50 min, plate 3518 B, K5, T04:24:56.930.fits =58.9 -- calibration: MARVELS1.2009-09-27T05:16:44.930.fits[0] 11.000000 47872.453125 5402.617676 TIO MARVELS1.2009-09-27T05:18:51.320.fits[0] 160.000000 319.187500 734.758301 THAR MARVELS1.2009-09-27T05:23:25.950.fits[0] 11.000000 47748.089844 5400.760742 TIO -- 05:02Z gotoFiend with cart. 9 plate 3513 A GSOGTF 05:26Z science 50 min, plate 3414 B, K10, T05:26:16.470.fits =41.7 -- calibration: MARVELS1.2009-09-27T06:18:12.580.fits[0] 11.000000 45815.089844 5375.581055 TIO MARVELS1.2009-09-27T06:20:17.980.fits[0] 160.000000 318.581238 733.543274 THAR MARVELS1.2009-09-27T06:24:52.570.fits[0] 11.000000 45971.636719 5379.135742 TIO -- 06:25Z go to field with plate 3513 field B to test the guider (because we can mount the imager and don't have time to finish the plate 3513 B.
