APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday September 26, 2008 (MJD 54736) ---=== OBSERVING TEAM ===--- Viktor Malanushenko Steph Snedden ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- A lot of clouds and a few spectro exposures on two plates. No plates declared done, but some progress was made. ---=== OBSERVING LOG ===--- Afternoon: ---------- Nothing unusual to report. Spectro focus left unchanged and set for about 8 - 11 deg. C. This setting worked well last night, and we expect similar temperatures tonight. Night: ------ At sunset, we had clouds and marginal humidity. The clouds persisted, with many tantalizing sucker holes until ... 08:12Z - We mounted cartridge 9, opened, and topped off the spectro dewars. 08:32Z - Cartridge 9, plate 3106 - SEGUE Jul08ce ------------------------------------------------ Needed an FK5 and had an approximately -10 asec offset in dec.
