APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday February 29, 2008 (MJD 54526) ---=== OBSERVING TEAM ===--- Elena Malanushenko swatters Howard Brewington (dayShift) ---=== OBSERVING PLAN ===--- sc13nc3! ---=== OBSERVING SUMMARY ===--- We had partly cloudy skies and mediocre seeing to begin the night but the weather improved and we had clear skies with decent seeing most of the time. We finished 5 plates (2938, 2913, 2414, 2148, & 2884) and acquired signal on another (2769). ---=== OBSERVING LOG ===--- Afternoon: ---------- I discovered no problems during the afternoon checkout. The spectro focus was checked but not adjusted; it's set for about +5.5 degrees C. The focus numbers via collimate are posted in the Problems Section. I mounted cart 09. The disk space at /data and /files was good; see below: Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 125G 9.7G 93% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 598G 273G 69% /data sdssfiles1:/data1/data 1.5T 538G 855G 39% /files iccSoundOff responded that all crates were available; see Problems Secion for command's output. 23:45Z Door/louvers opened and fans turned on.
