APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday October 15, 2007 (MJD 54389) ---=== OBSERVING TEAM ===--- Audrey Simmons (swing) Kaike Pan Howard Brewington ---=== OBSERVING PLAN ===--- SEGUE Science! ---=== OBSERVING SUMMARY ===--- The sky was photometric all night with good but variable seeing. Declared the following plates done: 2697, 2822, and 2826. And, we gathered about 3/5s of the needed S/N^2 for plate 2821. On the last two cartridge changes, we had a problem with the arm not wanting to go up when we tried to remove a cart from the bay. Yet, the arm would move down without a problem. We kept working with it until if finally picked up the cart. ---=== OBSERVING LOG ===--- Afternoon: ---------- Deleted MJD's 54383 & 84 for diskspace. Note there is only one more MJD that is safe to delete and the /data directory is at 24G as of now. Spectro collimation set for T=7C. 23:34Z - Started ventilation. Night: ------ 00:29Z We opened under photometric skies. 01:07Z Cart 02, plate 2821 (Seg faint). Guide stars found with goToField; seeing was about 1.0" as reported by the DIMM. SOS failed to post b1 and r1 of the first flat, viz., exposure #46725. However, SOS did not seem to have any trouble reducing the following science exposures. We tried an SOS redo for the failed flat but realized no satisfaction. So, we did a mid-cal, which was posted correctly. We completed several exposures but could not declare this plate done. 01:34 46725 10.0 flat 01:36 46726 2.0 arc 02:00 46727 1202.0 target 02:28 46728 1502.0 target 02:31 46729 10.0 flat 02:34 46730 2.0 arc 03:02 46731 1500.0 target 03:30 46732 1501.0 target 03:58 46733 1500.0 target 04:26 46734 1501.0 target 04:29 46735 10.0 flat 04:32 46736 2.0 arc 04:40Z Cart 04, plate 2822 (Seg faint).
