APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday April 17, 2008 (MJD 54574) ---=== OBSERVING TEAM ===--- Viktor Malanushenko (observer) Shannon Watters (observer) Dmitry Bizyaev (dayshift) ---=== OBSERVING PLAN ===--- Science? ---=== OBSERVING SUMMARY ===--- Clear skies with a nearly full moon. We did a MARVELS guider test (disabling fibers to see how well it keeps guiding). Acquired signal on SEGUE plate 2904. Took dithered spectro flats and had a mechanical problem after the first few flats. Read the log if you're really interested. ---=== OBSERVING LOG ===--- Afternoon: ---------- ntp_check ok iccSoundOff ok imager bias spectro bias ok idl> apo_plotbias, 52087 Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00052087.fit -5.5 -3.7 -2.6 2.9 7.3 9.2 10.6 sdR-b2-00052087.fit -8.3 -6.2 -4.6 1.4 7.7 8.9 11.4 sdR-r1-00052087.fit -7.2 -5.2 -3.2 1.8 7.8 9.1 11.8 sdR-r2-00052087.fit -7.9 -5.8 -4.7 1.6 7.8 9.9 12.0 Collimation adjusted for +0.5C on both sp1,sp. 00:40Z ventilation started Spectro dewar replaced.
