APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday January 16, 2009 (MJD 54848) ---=== OBSERVING TEAM ===--- Howard Brewington Dmitry Bizyaev Steph Snedden (swing) ---=== OBSERVING PLAN ===--- 16 Jan 2009 54848.0 0.55 BOSS/SEGUE until 06:42 (4.9 h), then SEGUE (5.9 h) ---=== OBSERVING SUMMARY ===--- Clear night, good seeing. Moon second part of the night. Imaging: - stripe 75 S imaged from lambda 156 to -172 (including ramps). Run 7912. - stripe 74 N imaged from lambda -177 to -153 (including ramps). Run 7913. - imager bias Spectroscopy: Finished cartridges 3 (3205), 8 (3178). Added useful signal to cartridges 5 (3207), 4 (3173). We leave the specrto dewar at low weight since somebody is expected today in here to change the dewar. ---=== OBSERVING LOG ===--- Afternoon: --------- No problems noted at the enclosure. Spectro focus is still set for an air temp of about OC. Removed MJDs 54816, 54817 data from sdsshost2/sdssfiles1. imager bias ok spectro bias 0k Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00058069.fit -5.8 -4.3 -3.2 2.0 7.3 8.5 10.7 sdR-b2-00058069.fit -8.3 -6.2 -4.6 1.4 7.7 8.9 11.4 sdR-r1-00058069.fit -7.0 -5.6 -3.7 1.4 6.4 8.3 10.4 sdR-r2-00058069.fit -8.4 -6.3 -4.7 1.1 6.3 7.9 10.0 23:38Z - started building ventilation Night: ----- 00:20Z opened enclosure. 00:40Z mounted the imager.
