APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday July 7, 2008 (MJD 54655) ---=== OBSERVING TEAM ===--- Howard Brewington Audrey Simmons Dan Oravetz (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds, rain, and high humidity kept up in all night. We completed MSP imager cals: linearity on u1-4 and QE on i2. The spectro dewer will need to be changed soon. Note: Sometimes the key-lock on the door nearest the loading dock area doesn't work. ---=== OBSERVING LOG ===--- Afternoon: ---------- We had problems with site utility power in addition to the site generator misbehaving. sdsshost2.apo.nmsu.edu % df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 130G 4.6G 97% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 651G 220G 75% /data sdssfiles1:/data1/data 1.5T 669G 725G 48% /files The Spectrograph Chiller Pressure gauge in the lower enclosure read just above 0 psi. The nominal range is 22 - 36 psi. This is probably an artifact of the power problems experienced on site and compressor #2 being down. After the generator started running better we power-cycled the spectro pump adjacent to the Spectrograph Chiller Pressure gauge and pressure increased to within nominal tolerances. When I tried taking a postCal prior to checking the spectro collimation, the goStare failed. The error and SOP output are in the Problems section. A spectro bias worked fine after the postCal problem. We checked the lamps at the telescope and they did not fire the way they should as was expected given the site power issues. When they did fire, the lamp brightness `hummed' with the same frequency that everything else did on site as a result of the generator running dirty. Once the generator calmed down and the generator power was steady, a postCal worked just fine. No adjustments made to spectrographs. sp1 set for ~14.5-15C and sp2 set for ~12.5-13C. Cartridge 3 is mounted. Night: ------ 03:34Z - There is no chance of opening (clouds, high humidity, and rain). We set up for imager cals.
