APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday February 12, 2007 (MJD 54144) ---=== OBSERVING TEAM ===--- Swing: Dan Long Night: Mike Harvanek Howard Brewington ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The first part of the night was lost to blowing snow, yet we finished four plates after midnight, i.e., 2484, 2707, 2601, and 1845. Some adjustments were to the cloud camera gain and sky_level settings; however, there's a new noise artifact in the raw images. French knows about this problem. Watcher reported vs+ and vt+ problems. The 2.5-meter flat_field screens seemed to make more noise than normal when opening and closing. And, we noticed that spectro auto_fill system seemed to make much less noise than in the past when we force a fill. ---=== OBSERVING LOG ===--- Afternoon: ---------- Found AD3 unresponsive when starting checks. Rebooted astro crate. No other problems with the afternoon check. Focus adjusted for the colder weather. Now set for about 1 C (using the spectro body temperatures). 23:50Z East Door Cracked, Louvers Open, Fans On Night: ------ We had blowing snow at sunset, so we waited. I (Howard) spent some time in the early evening making adjustments to the cloud camera. I noticed that there is a new artifact in the raw images and is located in the bottom left_hand side. I talked with French about this new problem, and he said that he would deal with it on Wednesday. 08:00Z Cart 08, plate 2484 (chunk143). An Fk5 was used to find the field. Plated was finished with three exposures. 09:33Z Cart 05, plate 2707 (seguefaint162). An Fk5 was used to find the field. Plate was declared done.
