Operations CXO Status Report

Friday 5 May 2006 8.00am EDT

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

A real-time procedure was executed on 3 May to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer.

Of note last week of the completion of a study into the long-term effects of radiation on the electronic components comprising Chandra's subsystems. The study concluded that major failures are not expected due to radiation damage through at least 15 years on orbit (the time-range used for the assessment).

The schedule of targets for next week is shown below and includes observations of GX 349+2 and GX 17+2 coordinated with RXTE.
