| During the last week Chandra completed the observing schedule as
planned.
Chandra passed through the remaining three eclipses of the 2007 Summer season on June 7, July 9 and 12 with nominal power and thermal performance. A real-time procedure was conducted on July 11 to set the short eclipse flag to "true" in preparation for the final eclipse of the season on July 12. A second real-time procedure was conducted on July 12 to disable SCS 29. A Chandra image release was issued on July 7 of the supernova remnant RCW 103. The Chandra data implies that the neutron star near the center is rotating once every 6.7 hours, confirming recent work from XMM-Newton. This is much slower than a neutron star of its age should be spinning and suggestive that the massive progenitor star may not have exploded in isolation. For further details see: http://chandra.harvard.edu/photo/2007/rcw103/ Of note last week was the X-ray Grating Spectroscopy meeting held July 11-13 in Cambridge and sponsored by the CXC. The meeting was well attended by over 80 participants. The schedule of targets for the next week is shown below. |
