During the last week Chandra completed the observing schedule as planned.

Chandra passed through the eighth and ninth eclipses of the fall season on Oct 9 and 12 respectively, with nominal power and thermal performance. A real-time procedure was executed on Oct 11 to back out a patch to the Control Processing Electronics (CPE). The patch had configured the CPE for the Draconid meteor shower on Oct 8. A second real-time procedure was executed on Oct 13 to update the on-board ephemeris. A third real-time procedure was executed on Oct 13 to re-initialize the flight software Thruster Command Processing subfunction in order to prevent the occurrence of an overflow condition.

A Chandra image release was issued on Oct 12 describing observations of G299.2-2.9, a supernova remnant found about 16,000 light years from Earth in the Milky Way galaxy. Evidence points to G299.2-2.9 being the remains of a Type Ia supernova. Because it is older than most supernova remnants caused by these explosions, at an age of about 4500 years, G299.2-2.9 provides astronomers with an excellent opportunity to study how these objects evolve over time.
