APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday April 12, 2009 (MJD 54934) ---=== OBSERVING TEAM ===--- Dmitry Bizyaev Audrey Simmons Nathen De Lee (MARVELS) Steph Snedden (support) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We gave MARVELS some SEGUE time at the beginning of the night to make up for the exchange of observing time between the two projects. SEGUE and MARVELS should be even now. Gained signal on: SEGUE cart 5, plate 3373 Observed MARVELS: Cart 7, plate 3356A Cart 9, plate 3277A&B Cart 4, plate 3416A&B Cart 6, plate 3418A Cart 1, plate 3357A We refocused the guider in the afternoon (see log for details). The zaphod computer had to be reset because the weather and cloud camera webpages crashed at 09:00Z. The weather page still does not show the outside dust counts. We gathered somewhere between 10k-15k dust counts on the mirror tonight, in rather humid conditions. Would the day staff please check the mirror tomorrow? Thank you. ---=== OBSERVING LOG ===--- Afternoon: ---------- Deleted the following MJD's from host2: 54902-54931 Now the disk space is: Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 117G 18G 87% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 841G 30G 97% /data sdssfiles1p:/data1/data 1.5T 670G 723G 49% /files Checked and set collimators for a night-time temperature of ~3C. We refocused the guider twice to get the best focus, but were not able to see the imperfections on the fibers (dirt, etc.). We think that we got it close. Also, the fibers have a rather large offset to the fiber mask. Steph was notified. 01:30Z - Began ventilating. Night: ------ We decided to give MARVELS some of the SEGUE time at the beginning of the night (to make up for previous time exchanged between the two projects). 01:28Z - Sunset. 01:40Z - Opened enclosure to mostly clear skies. Force-filled the spectrographs. 01:58Z - Began the MARVELS calibration sequence. 02:07Z - Mounted cart 7, MARVELS plate 3356A. 02:11Z - goToField. GSFOGTF. 02:22Z - 50 min exposure - T02:22:22.020.

Avg PMT 16.3 09:00Z - APO weather and cloud camera webpages crashed. We reset the Zaphod computer and things went back to normal. However, we were delayed from loading the next cartridge because the command would freeze at 'Starting Weather Handler'. Once Zaphod was back up and running, everything worked fine. 09:07Z - Calibrations. 09:07Z - Mounted cart 6, MARVELS plate 3418A. GSFOGTF. 09:25Z - 50 min exposure - T09:25:50.330.
