APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday June 27, 2008 (MJD 54645) ---=== OBSERVING TEAM ===--- Dmitry Bizyaev Shannon Watters Dan Oravetz (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The grade-2 GN2 dewar in the lower enclosure below the gauges that monitor the imager pneumatics, among other things, needs to be swapped out. We didn't open tonight because of clouds and rain. ---=== OBSERVING LOG ===--- Afternoon: --------- All systems checked and working properly. Mounted the corrector and cartridge 3, adjusted the counterweights to 250. sdsshost2.apo.nmsu.edu % df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 128G 6.5G 96% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 631G 240G 73% /data sdssfiles1:/data1/data 1.5T 591G 802G 43% /files Spectro focus set for ~13.8C (sp1) and ~13.2C (sp2).
