APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday January 15, 2004 (MJD 53020) ---=== OBSERVING TEAM ===--- Swing: Stephanie Snedden Night: Howard Brewington, Pete Newman Visitors: Ed Turner (Princeton U.), Alison Trumble (Southwestern U.) ---=== OBSERVING PLAN ===--- Science. ---=== OBSERVING SUMMARY ===--- Rain, high humidity and clouds prevented opening for a second night, with more bad weather in the forecast for several more days. ---=== OBSERVING LOG ===--- Swing: ====== Imager dewar swapped out at 23:30Z. A full 180-liter dewar was left in the SW corner of the enclosure for the next imager dewar swap. 23:26Z - Heater turned on in lower enclosure HVAC ducts. We left this switched on all night. Spectrograph focus checked and adjusted slightly. Details after the problems section. Telescope and instrument systems checks were without problems. Night: ====== Another night in the clouds with the humidity pegged at 100 per cent. We did not open, and eventually gave up at 09:30Z, running endNight onto the cloudy-night tapes. It being the 15th of the month, we held our regular Gourmet Night feast, and we now have a web page to record them on!
