Operations CXO Status Report

Friday 2 September 2016 9.00am EDT

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

Real-time procedures were executed on Aug 26-27 to dump OBC-A and -B memory as a follow-up to the patch uplinked on Aug 25. The dumps will be used to update the baseline memory images maintained on the ground.

A Chandra press release was issued on Aug 30 describing observation of the most distant galaxy cluster found to date. This cluster, called CL J1001+0220, lies about 11.1 billion light years from Earth. Galaxy clusters are the largest structures in the Universe held together by gravity. Chandra and the other telescopes may have captured this cluster at an important stage never seen before. For details see:

The schedule of targets for the next week is shown below and includes observations of SMC X-3, which was accepted as a Director's Discretionary Time Target of Opportunity on Aug 30, an observation of 1RXSJ010713.0-113554 coordinated with NuSTAR, and observations of Capella coordinated with XMM.
