Operations CXO Status Report

Friday 6 July 2018 9.00am EDT

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

A real-time procedure was executed on Jul 4 to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer.

Chandra passed through the sixth and seventh (and final) eclipses of the season on Jul 1 and Jul 4 respectively, with nominal power and thermal performance. Real-time procedures were executed on Jul 4 to disable SCS-29 and to dump and clear the EPS glitch counters as post-eclipse season actions.

The schedule of targets for the next week is shown below and includes an observation of Jupiter coordinated with Juno, and an observation of MXB 1659-298, which is a follow-up to a Target of Opportunity accepted on Mar 17, 2017.
