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

A flight software patch was uplinked on Aug 14 to update the on-board gyro calibration misalignment matrix. Real-time procedures were executed on Aug 15-16 to dump OBC-A and -B memory as a follow-up to the patch. The dumps will be used to update the baseline memory images maintained on the ground.

Additional real-time procedures were executed during each ground contact to reset the DSN Outage Dead Man Load.

A Chandra image release was issued on Aug 19 describing a new series of Chandra images that show pieces of Kepler's supernova remnant are moving up to 23 million miles an hour. These are extremely high speeds for an explosion that happened over 400 years ago as seen from Earth. Researchers used a Chandra spectrum and images obtained in 2000, 2004, 2006 and 2014 to measure the speeds of knots in the remnant. Kepler is a so-called Type Ia supernova, the thermonuclear explosion of a white dwarf star. For details see: https://chandra.harvard.edu/photo/2020/kepler/

The schedule of targets for the next week is shown below and includes an observation of gx5-1 coordinated with NuSTAR.
