Operations CXO Status Report

Friday 13 March 2009 9.00am EDT

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

A flight software patch was uplinked on Mar 6 to modify the RadMon process K-constants. The patch added the HRC anti-coincidence shield rate as a new channel used to monitor for high radiation. The step was taken to counter degradation in the EPHIN radiation detector due to increasing temperature trends through the mission.

A Chandra image release was issued on Mar 10 of the Medusa galaxy (NGC 4194). The composite X-ray and optical (Hubble) image shows a tidal tail formed by a collision between galaxies (Medusa's "hair"), and an black hole seem in X-rays. Recent research on a sample of galaxies including NGC4194 has investigated the correlation between the formation of stars and the production of X-ray binaries. For details see:

The schedule of targets for the next week is shown below.
