APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday July 9, 2008 (MJD 54657) ---=== OBSERVING TEAM ===--- Howard Brewington Shannon Watters Jon Brinkmann (support) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds and rain all night. We took imager cals. During afternoon setup we couldn't clear the alt axis because the "ops_cart_in_house" flag was unhappy. We Had to reseat the ops cart (imager cart) pin to clear the interlock. This has happened a few times now. While running the image calibrator the software froze and we weren't able to break out of it (cntrl-c 3 times). We killed the iop process and restarted the imager cal setup (twice). We were able to take test exposures and change settings through the software but then it would freeze when we tried running the uLeak script. The solution was to kill the old teamster (kill -9 #) and then remove the teamster log file (/tmp/sdss/teamster.imager). When we started another iop session it created a new teamster and log file and ran without problems. Thanks to Jon Brinkmann for showing us that log file. The grade 2 nitrogen for the imager dewar back pressure is < 500 psi. The imager and spectro dewars will need to be changed. ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems checked and working.
