APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday November 11, 2007 (MJD 54416) ---=== OBSERVING TEAM ===--- Howard Brewington Kaike Pan ---=== OBSERVING PLAN ===--- SN and Segue Science! ---=== OBSERVING SUMMARY ===--- Most of time. sky was clear, seeing was great at about 1.0 to 1.5". Imaging: 82 N, from lambda 110 to -123 (included ramps). Spectro: finished one segue plate 2728 (cart 7), and got signal on another segue faint plate 2700 (cart 8). ---=== OBSERVING LOG ===--- Afternoon: ---------- Afternoon checkout went smoothly. The spectro focus was checked but np adjustment made. still set for 6 C. Night: ------- 23:45Z mount imager and prepared for on-telescope bias 00:20Z run # 7154 on-telescope bias. 01:00Z run # 7155, 82 N. started scanStripe at lambda 108.0. The run started with nuErr at about 7.0", but gradually increased to 9.0" at frame # 400, lambda 170. In focus at frame # 24, lambda 111.3. 01:21Z started ramp at frame # 39, lambda 113.0. 01:29Z started at frame # 52, lambda 115.0. Skippy was happy from the begining. Seeing was great at about 1.0". 02:30Z, seeing became worse, to about 2.3" at frame # 155, quickly back to 2.0", then 1.5", at frame # 163, to 1.1" at frame # 180. 07:05Z clouds came in at about frame # 621, lambda about -160. 09:28Z, ended Science at frame # 853, lambda -125. 09:37Z, ended ramp at frame # 867, lambda -123. 09:42Z Due to satellite showed we had some clouds around though it was photometric when SN scan ended, we decided to switch to spectro. dismounted imager, and installed cart 7. 10:00Z cart 7, plate 2728 (segue faint). FK5 used. Seeing was about 1.0". The plate was DONE with three 1500 s exposures, combined with signals got on mjd 54415. 11:40Z cart 8, plate 2700 (segue faint). SOGTF. got one 1500 s exposure. The plate was not done yet. 12:50Z endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame
