APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday April 22, 2006 (MJD 53848) ---=== OBSERVING TEAM ===--- Night: John Barentine Viktor Malanushenko Visitors: Erica Ellingson (all from CU) Howard Yee Nils Alpers Jessica Jones Amy Bender ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds practically all time, and partly clear ... We are done four plates and one has obtained three exposure. It has also some troubles with software - remarks in to "Problems' session. Integrated dust counts were 4,500 at the 1.5 "dust-hours" ; then dust was over limit. No necessarly cleaning. ---=== OBSERVING LOG ===--- Afternoon --------- Dusty and windy, but no problems otherwise. Spectro focus numbers are in the Problems section.
