APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday April 26, 2008 (MJD 54583) ---=== OBSERVING TEAM ===--- Night: Dan Oravetz Victor Malanushenko Swing: Kaike Pan ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- With the humidity around 15% while we were open, we accumulated ~ 20,000 dust-hours before we closed to spiking dust counts, high wind, and clouds. The humidity rose to as high as 65% over the course of the night after we closed. Please check the mirror again in lieu of the increased humidity. Thanks again. We quite acceptable conditions without Moon and high dust 6-7K. We observer two plates: - 2851, DONE. - 2861, accumulated acceptable S/N. The last exposure was canceled so as rose dust counts and humidity. We run imager calibration linearity and QE 'i3' test. ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems were checked and working properly. Spectro focus was set for 8 C. Dust count was at 5 K. No ventilation started. Night: ------- The sky is quite photometric and no Moon evening. Dust level is 4-5K, very high. We decided do not start ventilation in advance and open telescope on Sunset. 01:50Z Enclosure off, start vent.
