APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday May 29, 2008 (MJD 54616) ---=== OBSERVING TEAM ===--- Kaike Pan Howard Brewington Audrey Simmons (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Black cloth problems again; see log. The telescope vibration is baaaack; see log. Completed plates: 2929, 2818, 2490, 2724, and 2797. During a few of the arcs, we checked the neon lamps; they all worked. The integrated dust count was about 10K for the night. ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems during checkout. Spectro Collimation set for ~12C tonight. Started ventilating at 01:10Z, with doors and louvers open, fans on. Night: ------ 02:01Z Sunset 02:12Z Enclosure off, topped-off spectro secondary dewars, checked top/bottom balance, did a test slew, checked fiducial crossings for each axis, and started the DIMM. The black cloth that covers the laptop at the 2.5-meter has gone missing. We're guessing that some star-struck individual grabbed it as a souvenir and that it will appear on eBay very soon. Nevertheless, we would really appreciate receiving another one. Thanks. Black cloth update: When we closed of the night we found the black cloth in the trash can next to the west door of the 2.5-meter. 02:37Z Cart 01, plate 2929 (segFaint180). An fk5 was used to find the field. We had clouds moving toward the site from the southwest.

The scope was, of course, moving in az and rot when the problem occurred. Since the vibration was VERY bad this time, we decided to move the scope to instChange with a track command in TCC, which did not move az and rot at the same time.
