APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday October 21, 2008 (MJD 54761) ---=== OBSERVING TEAM ===--- Elena Malanushenko (swing) Viktor Malanushenko (observer) Howard Brewington (observer) Nathan De Lee (Marvels team) ---=== OBSERVING PLAN ===--- Science! BOSS/SEGUE & MARVELS ---=== OBSERVING SUMMARY ===--- Sorry Wendell, but there might be a problem with LN2 force-fill of sp1; see log. French asked that we leave the auto-fill lines disconnected this morning. We added signal to the following segue plates: 3128, 3143, and 3144 More exposures were done on the following MARVEL plates: 3055 and 3060 with twilight tests at the end of night. ---=== OBSERVING LOG ===--- Afternoon: --------- All systems checked and working properly. Used cart 3 plate 3144 for collimation. Collimation is set for 10 C. Mirror number E for primary was 0.04 out of nominal value, I relaxed primary and it fixed the problem. 23:30 started ventilation Cart 4 is mounted. There was imager ion pump critical alert today. French worked with this but it is not possible to fix the problem now. It is still ok to use imager tonight if weather permit. Night: ====== 00:20Z Sunset 00:21Z Enclosure off, topped-off spectro secondary dewars, checked top/bottom balance, did a test slew, checked fiducial crossings for each axis, and started the DIMM. When the spectro dewars were topped-off, sp1 started but then stop after a few seconds although its 10-L dewar was not full. So, sp1 was filled in manual mode. This also happened two nights ago but was dismissed because the spectros had recently filled. So, there may be a problem with the force-fill mode of sp1. 00:55Z Cart 04, 3128 (Segue). Found guide stars with FK5 in bright twilight. Seeing ~ 1.7" as reported by the guider. The first exposure did not appear in the nightLog or SOS because the teamster had failed. The teamster was restarted. Although the sky is photometric, the seeing is not good enough to change to the imager. 01:31 55691 10.0 flat 01:33 55692 2.0 arc 01:44Z Twilight ended 02:03 55693 1501.0 target 02:31 55694 1500.0 target 02:36 55695 10.0 flat 02:39 55696 2.0 arc 03:08 55697 1500.0 target MJD b1 r1 b2 r2 Texp ---------------------------------------- 54759 4.3 3.6 2.8 2.2 1500.0 54759 5.0 4.1 3.4 2.6 1801.0 54759 4.7 4.1 2.7 2.7 1800.0 54761 2.8 2.7 2.6 2.2 1501.0 54761 2.9 2.6 2.5 2.2 1500.0 54761 3.1 3.1 2.5 2.4 1500.0 ---------------------------------------- Total: 22.8 20.2 16.5 14.3 9602.0 Note: When I changed to cart 08, I noticed that the lights in lower enclosure had been left on from the afternoon checkout. Although the door to the lower enclosure was of course closed, some light was leaking from the cracks on the east end of the door. SOS did not complained, so I hope the above exposures are good. 03:16Z Cart 08, 3143 (Segue). An FK5 star was used to find the field. The teamster failed again and was restarted after several tries. The seeing was about 1.8" as reported by the guider. 03:24 55698 10.0 flat 03:26 55699 2.0 arc 04:04 55700 1501.0 target 04:32 55701 1500.0 target 04:35 55702 10.0 flat 04:38 55703 2.0 arc MJD b1 r1 b2 r2 Texp -------------------------------------- 54761 5.9 5.1 5.7 4.9 1501.0 54761 6.9 5.9 7.2 5.0 1500.0 -------------------------------------- Total: 12.8 11.0 12.9 9.9 3001.0 04:42Z Cart 03, 3144 (Segue).
