Operations CXO Status Report

Friday 15 April 2011 9.00am EST

During the last week the observing schedule was replanned to include a series of observations of the Crab Nebula that was accepted as a Target of Opportunity on Apr 12. The replanned loads were uplinked on Apr 13. Planned observations of IGR J15415-5029, SLJ1647.7+3455, and NGC 7008 were impacted and will be rescheduled at a later date.

Real-time procedures were executed on Apr 14 in preparation for the start of the 2011 spring eclipse season: one to activate SCS 29 and one to dump and clear the EPS glitch counters. An additional real-time procedure was executed on Apr 14 to perform a diagnostic dump of the Central Processing Electronics (CPE). Chandra passed through the first eclipse of the season on Apr 15 with initial indications of nominal power and thermal performance.

A Chandra image release was issued on Apr 13 describing a search for the Milky Way's most massive stars, using data from Chandra and Spitzer. Dust and gas obscure much of the view of the plane of our Galaxy from optical telescopes. X-rays can penetrate this veil and help astronomers study these giant stars. For details see:

The schedule of targets for the next week is shown below and includes one of the series of the Crab Nebula Target of Opportunity observations, observations of FK Com coordinated with the HST, and an observation of MAXIJ1659-152 coordinated with the EVLA.
