Real-time procedures were completed on Sep 2 to uplink and test a
software patch to modify the threshold criteria for triggering science
instrument safing under high radiation conditions. The change
increases the number of sequential frames from EPHIN required to
trigger a high radiation condition from 4 to 10 and will significantly
reduce the number of unwanted triggers just prior to radiation belt
entry. The uplink and test proceeded nominally.

A Chandra image release was issued on September 3 showing the
aftermath of a glancing collision between two galaxies in the Virgo
cluster.
