APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday May 19, 2007 (MJD 54240) ---=== OBSERVING TEAM ===--- Swing: Viktor Malanushenko Observers: Kaike Pan, Dan Oravetz ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Most of the night was lost to clouds. Clouds and nearby lightning from the start of the night until about 07:10Z. Spectroscopy: ------------ Finished Cartridge 6, plate 2754. got two exposures on cartridge 7, plate 2516. ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems, everything is OK. Spectro has been adusted to night Temp=+8C with Cartridge 6 mounted. Heavy clouds & close thunderstorms at 00:00Z Night: ------ 02:00Z-06:00Z clouds and radar returns kept us from opening, nearby lighting kept us from doing imager calibration. 06:35Z - Began ventilation. Doors and louvers opened, fans on. 07:16Z - Enclosure off. Cartridge 6, plate 2754, chunk165, Legacy. Guide stars found on gotoField. 07:40Z - Pre-Calib. 07:46Z - 20-minute exposure. 08:12Z - 20-minute exposure. 08:34Z - 20-minute exposure. Seeing: 1.4 - 1.6". The plate was Done combined with signals got on MJD 54239.
