APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday September 8, 2008 (MJD 54718) ---=== OBSERVING TEAM ===--- Dmitry Bizyaev Howard Brewington Support: Steph Snedden MARVELS Team ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The spectro dewars needs to be changed. The east door of the Lindy cart house is not closing properly, and the lock does not work either. The DIMM's fan is working again (Thanks Wendell). We wrote a "tentative" procedure for MARVELS observations; this document is located at sdsshost2:/home/observer/marvels.txt Please feel free to use and augment it as necessary. ---=== OBSERVING LOG ===--- Afternoon: ---------- The murmur server was unhappy; so Host2 and the crates were rebooted. In fact, Steph used the toggle switches on the back of the racks to power off the crates. Spectro focus was checked but not adjusted; it's set for 12-degrees C. The Collimate numbers are posted in the Problems Section. im> df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 112G 23G 83% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 666G 205G 77% /data sdssfiles1:/data1/data 1.5T 641G 752G 47% /files We tested the DIMM's new fan; it worked well. 12:20Z Opened doors/louvers and turned on fans. 01:01Z Closed doors/louvers and turned of fans as humidity increased.
