APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday May 19, 2004 (MJD 53145) ---=== OBSERVING TEAM ===--- Dan Long Jurek Krzesinski Mike Harvanek (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The weather held us to less than two hours on sky tonight. We got three exposures on plate 1580 before having to close. It wasn't quite enough to finish the plate. ---=== OBSERVING LOG ===--- Afternoon: ---------- Spectro collimation adjusted. Details in the Problems section. xxx Night: ------ Clouds and occasional sprinkles kept us closed the first half of the night. High winds kicked up between 05:00Z and 07:00Z. The winds died and the clouds thinned by 08:00Z, so we opened. We took guider darks this evening in warm conditions, but found later that it hadn't generated new files in the /data/spectro/guiderDarks directory. The command listed in folklore is guiderDark 10 30. Should it be multiGuiderDark 10 30? 07:00Z Doors Open, Fans On 08:00Z Enclosure Open Cartridge 4 Plate 1580 08:16Z gotoField Guide stars on slew. 08:27Z preCalib 08:34Z First Science 26870 postCalib recommended from first science exposure. 09:35Z Dust counts go over 3000 during 3rd exposure Clouds return as well.
