APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday June 14, 2009 (MJD 54997) ---=== OBSERVING TEAM ===--- Dmitry Bizyaev Howard Brewington ---=== OBSERVING PLAN ===--- SEGUE2 Science! ---=== OBSERVING SUMMARY ===--- Most of the night was lost to clouds and radar returns. Added signal to: Cart 05, plate 3480 The spectro dewar needs to changed. When we changed the spectro dewar yesterday afternoon, we noticed that its pressure valve was not working. We left this dewar next to the PT stairs. Please check the valve. Thanks! ---=== OBSERVING LOG ===--- Afternoon: ---------- 23:00Z Restarted servers. 23:20Z [hjbrew@sdsshost2 notes]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 119G 16G 89% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 762G 109G 88% /data sdssfiles1p:/data1/data 1.5T 605G 788G 44% /files 23:35Z Started the spectro collimate checkout.
