Operations CXO Status Report

Friday 31 January 2014 9.00am EST

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

A real-time procedure was executed on Jan 27 to perform a diagnostic dump of the Control Processing Electronics (CPE) memory.

Preparations are complete for the winter 2014 eclipse season; the season contains 9 eclipses and runs from Jan 30 to Feb 20. Real-time procedures were executed on Jan 29 to prepare for the first eclipse: one to activate SCS 29 and one to dump and clear the EPS glitch counters. Chandra passed through the first eclipse of the season on Jan 30, with nominal power and thermal performance.

A Chandra press release was issued on Jan 27 as a NASA press release describing planned observations of SN2014J, an exceptionally close stellar explosion discovered on Jan 21. SN 2014J, occurred in the galaxy M82 and lies only about 12 million light-years away. This makes it the nearest optical supernova in two decades and potentially the closest type Ia supernova to occur during the life of currently operating space missions. For details see:

The schedule of targets for the next week is shown below and includes an observation of MAXI J1421-613, which was accepted as a Target of Opportunity on Jan 16, observations of KOI-314 and SN2014J, which were accepted as a Director's Discretionary Time TOOs on Jan 21 and 23 respectively, an observation of SDSS J1133+1142 coordinated with the Hobby-Eberly Telescope, and an observation of NGC 5548 coordinated with HST.
