APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday April 8, 2008 (MJD 54565) ---=== OBSERVING TEAM ===--- Shannon Watters (observer) Viktor Malanushenko (observer) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds and high dust level all the time. We obtained good signal on two plates. We was closed after 7:50 because clouds and dust. The integrated dust was around 27K. During twilight we have lead short experiment : guiding used three fibers only. The fibers 1-8 have been disabled, and then start guiding during time approx 2 min. No errors on positions, but the scale was wrong. We have continued the Imager's calibrations (MSP). ---=== OBSERVING LOG ===--- Afternoon: ---------- Spectrographs set for 5.4 C to 7.7 C (~6.5C) 01:00Z - Began ventilation. Doors and louvers opened, fans on. 01:38Z - Enclosure off.
