APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday February 28, 2009 (MJD 54891) ---=== OBSERVING TEAM ===--- Observers: Dmitry Bizyaev Howard Brewington ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The DIMM is not working; see afternoon checkout. Added signal to the following: Cart 03, plate 3209 Cart 08, Plate 3233 DONE Cart 02, plate 3244 Cart 01, plate 3236 There was a problem with Cart 04, plate 3000; see log. ---=== OBSERVING LOG ===--- Afternoon: ----------- The DIMM is not happy at present; the slew buttons on the hand paddle are not working again. I also noticed that some of the buttons are sticking, which is confusing the scope's mount. I will contact Meade on Monday for a quote on a replacement paddle. The paddle is now disconnected. Spectro focus was checked but not adjusted; numbers are in Prob Section. Night: ------- 00:00Z Doors and louvers opened; fan on 00:56Z Sunset 01:00Z Enclosure off, topped-off spectro secondary dewars, checked top/bottom balance, did a test slew, and checked fiducial crossings for each axis. 01:27Z Cart 03, plate 3209 (Dec08aSEGUE2). Field was found in twilight with an FK5. The first guider frame was #1111.

An FK5 was used to find the field. The first guider frame was 1467. This plate/field was very odd, i.e., the guide stars were very faint. In fact, we used 40-second exposures with the guider through thin clouds and could barely see the guide stars. So, we moved on to Cart 08. 06:16Z Cart 08, plate 3233 (Jan09aSEGUE2). An FK5 was used to find the field. The first guider frame was 0053.
