APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday March 6, 2008 (MJD 54532) ---=== OBSERVING TEAM ===--- Steph Snedden swatters Howard Brewington (dayShift) ---=== OBSERVING PLAN ===--- Scientology! ---=== OBSERVING SUMMARY ===--- Cloudy conditions and eventually some light snow kept us from taking science exposures most of the night. We did acquire signal on 2 plates (2914, 2947). ---=== OBSERVING LOG ===--- Afternoon: ---------- I discovered no problems during the afternoon checkout. The spectro focus was checked and slightly adjusted; it's set for about -2.0 degrees C. The pre-focus numbers via collimate are posted in the Problems Section. The disk space at /data and /files was good; see below: Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 127G 8.2G 94% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 622G 250G 72% /data sdssfiles1:/data1/data 1.5T 554G 839G 40% /files I RMed some "Safe To Remove" files in /data/*/MJD iccSoundOff responded that all crates were available; see Problems Section for command's output. 23:00Z Opened doors/louvers, turned on fans.
