We didn't open. QE for u4,u5, and u6 was done. We replaced the imager dewar in the morning but we leave the spectro dewar at 97 lbs (filled at ~05Z). ---=== OBSERVING LOG ===--- Afternoon: ---------- ntp_check ok iccSoundOff ok imager bias ok spectro bias ok Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00053844.fit -5.5 -4.4 -3.1 2.1 7.4 8.8 10.5 sdR-b2-00053844.fit -8.3 -6.7 -4.5 1.8 6.8 9.3 10.6 sdR-r1-00053844.fit -7.3 -5.1 -4.0 1.4 6.9 9.0 10.2 sdR-r2-00053844.fit -7.8 -5.7 -4.5 0.7 6.0 8.0 10.1 Spectro collimation is set to 13.5C. clouds and rain at the evening, so we set up the imager for calibrations.
