ACE 2 hr fluence is 8.9e6 vs. threshold 3.6e8. CRM-based orbital fluence is 0.0e0 vs. threshold 3.0e9. Chandra is in the magnetosphere. 4) Quick Look data review (OK unless noted): Seq # ObsID It Constr. Target Start Time SI Grat Comment ------------------------------------------------------------------------------------------ There were no new quicklook datasets in this shift. 5) ACIS EGSE in the TST room is not receiving realtime telemetry. The ACIS team has been notified. 6) The near-Earth ACA test was successful. All 8 stars were acquired at each angle (5,6,7,8,9,10,11,12 degrees) from the bright Earth limb.
