APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday April 25, 2009 (MJD 54947) ---=== OBSERVING TEAM ===--- Alaina Shelden Dmitry Bizyaev ---=== OBSERVING PLAN ===--- SEGUE2 spectroscopy ---=== OBSERVING SUMMARY ===--- Site's idl server was down twice in the evening. Fixed twice. We are with the same problem with photo crate 2. Mostly clear night with accidentaly running clouds High wind in the evening. Par tof night was lost due to the wind. Got signal with plates 3285 (c. 6) and 3408 (c 4) Finished plate 3388 (c. 3) ---=== OBSERVING LOG ===--- Afternoon: ---------- Sitewide problem: idl server is down, tasks which use idl don't work : sos, cloud camera, etc. Following Jon's directions, galileo2 server is reseted. idl works. All other services got alive. spectro bias ok Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00060721.fit -5.9 -4.1 -3.1 2.2 7.3 8.5 10.6 sdR-b2-00060721.fit -8.5 -6.2 -4.7 1.2 7.4 8.6 11.1 sdR-r1-00060721.fit -7.5 -5.6 -3.5 1.5 6.5 8.5 10.5 sdR-r2-00060721.fit -8.1 -6.1 -4.9 1.3 6.5 7.7 9.8 Collimation checked and found good for +10 C. 01:10Z Ventilation started.
