APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday April 15, 2009 (MJD 54937) ---=== OBSERVING TEAM ===--- Howard Brewington Audrey Simmons Alaina Shelden (training) ---=== OBSERVING PLAN ===--- SEGUE2 and MARVELS Science! ---=== OBSERVING SUMMARY ===--- The last few hours of the night were lost to clouds. Added signal to the following: Cart 01, plate 3362 Cart 08, plate 3246 Cart 07, plate 3414-B Cart 03, plate 3418-A (clouds) We had no output from fibers 23/24 on cart 07 As last night, endNight did not copy the IRSC images. The guider lost the guide stars as clouds passed in front of the telescope with cart 01; see log. The weather_page dust counters were not working; we used the hand-held. Alaina came in again today for more training with the afternoon checkout. ---=== OBSERVING LOG ===--- Afternoon: --------- 23:00Z Alaina and Howard started the afternoon checkout; Alaina did most of the checkout for additional practice. 23:40Z Started the specto_focus check. 23:50Z Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 117G 18G 87% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 827G 44G 95% /data sdssfiles1p:/data1/data 1.5T 661G 732G 48% /files 00:20Z Checkout completed; ventilation was not started because of dust and high winds. Night: ------ 01:31Z Sunset; winds decreased. 01:35Z Dust measured with hand-held counter was ~2K. 01:40Z Door/louvers opened; fans on 01:55Z 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. 02:28Z Cart 01, plate 3362 (Mar09_SEGUE2). And FK5 was used to find the field. The guide stars were lost during the first exposures while a cloud passed in front of the field; the cloud was only a probleme for a few minutes. Seeing was about 1.7" as reported by the guider. Again, while clouds passed in front of the telescope, the guider lost the field; the clouds were only a problem for a few minutes. Each time, the exposure was paused, and goToField was re-issued. Four exposures were completed; see below: 02:40 60420 10.0 flat 02:42 60421 2.0 arc 03:00 twilight end 03:12 60422 1502.0 target 03:30 Dust still at ~2K 03:41 60423 1502.0 target 03:44 60424 10.0 flat 03:46 60425 2.0 arc 04:20 60426 1800.0 target 04:48 60427 1500.0 target 04:51 60428 10.0 flat --------------------------------------------------- MJD b1 r1 b2 r2 Texp Sum --------------------------------------------------- 54935 8.2 4.5 8.9 4.1 1800.0 25.7 54935 3.5 2.2 4.8 2.2 1800.0 12.7 54935 0.2 0.2 0.2 0.1 1279.0 0.7 54937 5.1 3.7 5.6 3.3 1502.0 17.7 54937 4.9 3.4 5.4 3.4 1502.0 17.1 54937 7.5 4.8 8.9 4.9 1800.0 26.1 54937 6.1 3.7 7.2 4.0 1500.0 21.0 --------------------------------------------------- Total: 35.5 22.5 41.0 22.0 11183.0 --> 121.0 Total when ALL b,r values > 2.0: 35.3 22.3 40.8 21.9 9904.0 --> 120.3 (limit=156.5) 04:50Z Dust measured with hand-held counter was ~2K; humidity had increased to about 50%. 05:02Z Cart 08, plate 3246 (Jan09a_SEGUE2).
