APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday February 26, 2003 (MJD 52697) ---=== OBSERVING TEAM ===--- Swing: Jurek Krzesinski Night: Dan Long, Pete Newman Visitors: David Schlegel (PU), Michael Blanton (NYU), Cristy Tremonti (JHU) ---=== OBSERVING PLAN ===--- Science. ---=== OBSERVING SUMMARY ===--- Another 3+ inches of snow during the day may be keeping the forest nicely damp but it also kept the telescope in the enclosure with high humidity and heavy cloud cover, and we gave up at 10:30Z. We are now 0 for 8 this dark run. ---=== OBSERVING LOG ===--- Afternoon checkout: DA, MIGs, spectro guider ok.
