APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday May 8, 2008 (MJD 54595) ---=== OBSERVING TEAM ===--- Night: Viktor Malanushenko, Dan Oravetz Swing: Kaike Pan ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We battled partly cloudy skies the first half of the night. The clouds thinned out the second half of the night allowing for more efficient data collection. Finished: cartridge 5, 2932 cartridge 4, 2188 Obtained signal on: cartirdge 3, 2561 We accumulated around 33,000 dust-hours. Humidity was around or below 20%. ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems were checked and working properly. The spectro focus was set for 8.5 C. Data for MJDs 54580-54585 were removed. Dust count varied from 3k to 8.5k. No evening ventilation. Cartridge 1 was mounted for the beginning of the night.
