Operations CXO Status Report

Friday 5 May 2017 9.00am EDT

A real-time procedure was executed on May 1 to uplink a flight software patch that updates the residual threshold used by the Aspect Camera in determining the attitude solution. This patch should limit the impact of spurious hot pixels on the attitude solution. Additional real-time procedures were executed on May 2 and 3 to dump OBC-A and -B memory as a follow-up to the patch. The dump will be used to update the baseline memory images maintained on the ground. A real-time procedure was executed on May 3 to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer.

A Chandra press release was issued on May 2 describing observations of the Perseus Galaxy Cluster. Combining data from Chandra with radio observations and computer simulations has revealed a vast wave of hot gas spanning some 200,000 light-years in the Perseus galaxy cluster. For details see: http://chandra.si.edu/press/17_releases/press_050217.html

The schedule of targets for the next week is shown below and includes an observation of SDSS J1338-0124, which was accepted as a Target of Opportunity on Apr 11, PSR J1622-4950, which was accepted as a Target of Opportunity on May 3 and is coordinated with NuStar, IGR J17445-2447, which was accepted as a Target of Opportunity on Apr 25.
