APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday April 9, 2009 (MJD 54931) ---=== OBSERVING TEAM ===--- Dan Oravetz (observer) Dmitry Bizyaev (observer) Nathan De Lee (MARVELS team) ---=== OBSERVING PLAN ===--- MARVELS Science ---=== OBSERVING SUMMARY ===--- First part of the night in light clouds, second part passed in denser clouds. MCP got frozen twice. Weather page screwed up. Exposed cartridges: 7 - 3356A 8 - 3351B (missed fibers in frame: 3,4 7,8 43,44 47,48) 3 - 3417B 4 - 3416 A & B 9 - 3277 B - very poor signal 04:19Z MCP got unavailable. 06:53Z same boo again; MCP rolled back to v6_4_0. Stable since that time. Server zaphod was reseted because weather pages got unavailable around 5:55Z. Some features like dust particle counts were not restored after the reset. Need attention, please. -- About the MCP, may ne this is not relevant, but I noticed that with the newer testing version the system (sdsshost2) looked noticeably more loaded. Murmur log and tcc both had more dense flow of messages. -- ---=== OBSERVING LOG ===--- Afternoon: ---------- After starting MCP we found that the axes are in "**BS" status, not "ABS" as usual. Watcher reports that all axes are on their brakes. After the telescope check everything turned to be normal. TEmperature is the same as it usually been last nights, so we don't adjust spectro collimation. 00:25Z ventilation started, louvers and doors opened.

More clouds after we started exposure. =9.5 09:54Z calibration --- Clouds made observations useless. We're waiting for more clear sky from the heavens. Or vice versa. 11:00Z still the same. 11:30Z enclosure on. Ventilation switched to internal. Doors and louvers clossed. 11:39Z endNight rejoiced.
