APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday March 9, 2010 (MJD 55265) ---=== OBSERVING TEAM ===--- Steph Snedden Audrey Simmons ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Stayed closed all night due to humidity, clouds, wind, some radar returns, and cold temperatures. Completed spectro biases and darks. Cartridge 14 check re-done. Pending further analysis, we should be able to put this cartridge back in service. ---=== OBSERVING LOG ===--- Afternoon: ---------- 23:00Z - Cartridge 14 mounted. Flat, arc and Hartmanns taken to adjust collimation.
