| During the last week the observing schedule was replanned twice to include two observations accepted as Targets Of Opportunity (TOO). The X-ray transient RX J170930.2-263927 was accepted on 11 March and observed on 12 March, and the supernova SN20020B was accepted on 12 March and observed on 14 March. Observations of IRAS20051-1117, PSS 0958+0740 and FTM0738+2750 were impacted by the TOOs and will be observed in a later schedule.
Real-time procedures were completed nominally on 12 March to update the spacecraft ephemeris and on 14 March to perform a charge injection test with ACIS. A press release was issued on March 13 announcing that the "twin" quasars Q2345+007 A,B previously considered to be an optical illusion, are now thought to have been produced by merging galaxies. For details see: http://chandra.harvard.edu/press/02_releases/press_031302.html. Of note this week is the deadline for submission of Chandra cycle 4 proposals a 19:00 EST on March 15. The observing schedule for the next week is shown below and includes a follow-up observation of the TOO RX J170930.2-263927 and a phase constrained observation of Cgynus X-1. |
