APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday March 24, 2009 (MJD 54915) ---=== OBSERVING TEAM ===--- Elena M Alaina Shelden ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Plate 3319 (cart 3) declared done. Clouds rolled in, and gave us horrible efficiency half the night. ---=== OBSERVING LOG ===--- Afternoon: ---------- Telescope is checked and all systems work properly. Jon rebot sdsshost2 and its work fast now. Guider paraline has been replaced by Jon as it has red lid after sdsshost2. Collimate set for 3/2C. Lanrdu X-term had problem with copying blocks so I need to reboot X.
