APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday April 16, 2009 (MJD 54938) ---=== OBSERVING TEAM ===--- Howard Brewington Alaina Shelden ---=== OBSERVING PLAN ===--- SEGUE2 Science! ---=== OBSERVING SUMMARY ===--- Cloudy with potential rain most of the night. Opened at about 10:00Z. Ended MARVELS run with end-of-run calibs done while closed. Added signal to: SEGUE Cart 7 plate 3297 current s/n 79.4 endNight failed to copy cloudcam images for the 3rd night in a row. ---=== OBSERVING LOG ===--- Afternoon: ---------- 23:00Z Started the checkout. 23:33Z Started the spectro focus check. 23:39Z Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 117G 18G 87% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 828G 43G 96% /data sdssfiles1p:/data1/data 1.5T 662G 731G 48% /files Night: ------- 00:48Z Very windy and checked the dust--1.9K as of now. 01:31Z Sunset 01:39Z Dust at 4.5K with humidity at 71% (and rising) 02:16Z Dust is 2.5K with humidity at 84.7% and temp at -5.4C 02:36Z Dust is around 2K with humidity about 71% and temp at -5.3% 02:59Z Evening twilight (18 deg) 02:59Z Dust is at 1.5K, humidity at 66% and temp at -5.3C. Starting ventilation. Stars twinkling alot. 03:26Z Clouds becoming a problem... Deciding to wait until the next cloud clump passes. 05:33Z Closed doors partially due to radar signals.
