| Last week the observing schedule was interrupted due to high radiation associated with solar flare activity. The loads were halted on March 18 at 9:51am EST through a ground command to execute the SI Safing SCS 107. This ensured that the accumulated radiation dose for ACIS remained below the allowed threshold. Loads were rebuilt for uplink on March 20, when the radiation environment reached an acceptable level.
Of note last week was the Chandra Cycle 4 proposal deadline at 7pm EST on March 15. A total of 818 proposals were received and the submission process proceeded smoothly. The observing schedule for the next week is shown below and includes a tightly constrained observation of the target G292.2-0.5. |
