APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday June 2, 2008 (MJD 54620) ---=== OBSERVING TEAM ===--- Dmitry Bizyaev Howard Brewington ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We did not open because of very high pollen. Completed imager cals: Lin for U5 and U6 Qe for U5 and U6 ---=== OBSERVING LOG ===--- Afternoon: ---------- We had discovered no problems during the checkout. Spectro focus was checked but not adjusted; it's set for about +17-deg C. Night: ------ 01:35Z Doors/louvers opened and fan on 02:02Z Doors/louvers closed and fans off as pollen was detected on Dmitry's windshield. So, we cleaned his windshield again , and waited an hour for another test of pollen. 02:06Z Sunset 02:30Z We began the setup for imager cals. 03:00Z We checked Dmitry's windshield for pollen and found lots. Since we had increased cloud cover, as well, we decided to go ahead with imager cals. 03:35Z MSP bias fr. 1, run 7539.
