During the last week Chandra completed the observing schedule as planned. A real-time procedure was executed on Apr 14 to perform a diagnostic dump of the Control Processing Electronics (CPE). A second real-time procedure was executed on Apr 15 to re-initialize the flight software Thruster Command Processing subfunction in order to prevent the occurrence of an overflow condition. A Chandra image release was issued on Apr 16 describing observations of the globular cluster NGC 6388. A planet may have been ripped apart by a white dwarf star in this globular cluster in the outskirts of the Milky Way. A white dwarf is the dense core of a star like the Sun that has run out of nuclear fuel. Combining data from Chandra and several other telescopes, researchers think a "tidal disruption" may explain what is observed. For details see: http://chandra.si.edu/photo/2015/ngc6388/ The schedule of targets for the next two weeks is shown below and includes an observation of SN2014C, accepted as a Director's Discretionary Time TOO follow-up on Dec 15, and an observation of the Cas A CCO, accepted as a Director's Discretionary Time TOO on Mar 9. |
