APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday December 31, 2008 (MJD 54832) ---=== OBSERVING TEAM ===--- Howard Brewington Dan Oravetz ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Mice have eaten holes in all of our Cryo-gloves except one pair. We put the last good pair in the cabinet on the north wall of the upper-level of the 2.5-meter enclosure. We need to order more gloves. Added signal to plates: 3109, 3177, and 3186 Completed plates: 3163, 3195, and 3167 Did scanStripe 85 N -startLambda -163 -endLambda -140 (not including ramps). All of Dan's xterm sessions stopped working during this scan; see log. ---=== OBSERVING LOG ===--- Afternoon: ---------- No Problems to report. The spectro focus was checked but not adjusted; see Problems Section for focus numbers via Collimate. The enclosure temp at the time of test was 6.5-degrees C. 23:05Z Doors/louvers opened, fans on Night: ------ 00:07Z Sunset 00:09Z 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. 00:51Z Cart 06, plate 3109 (Jul08ceSegue2). An FK5 and last night offset were used to find the field. Completed two exposures; see below. 01:23 57725 10.0 flat 01:26 57726 2.0 arc 01:35 Twilight end 02:01 57727 1800.0 target 02:34 57728 1800.0 target 02:38 57729 10.0 flat 02:40 57730 2.0 arc MJD b1 r1 b2 r2 Texp Sum --------------------------------------------------- 54831 6.3 3.6 6.0 4.7 1801.0 20.6 54831 7.8 5.5 9.1 6.0 1801.0 28.4 54832 7.5 4.7 9.7 6.6 1800.0 28.5 54832 6.3 4.9 8.4 5.9 1800.0 25.5 02:45Z Cart 05, plate 3186 (Nov08cSegue2).

I had to take control of the focusLoop, skippy, and the seeingRun sessions to complete 90% of the scan, yet all went well. 06:23Z On-telescope bias, 38-frames, (run # 7886). 06:38Z Removed imager, mounted corrector lens and cart 03, did a top/bottom balance check. 06:57Z Cart 03, plate 3163, field B, (Nov08b_Mar_pre).
