During the last 24 hours, Chandra completed GTO observations of CL0117+31 with ACIS-I, Cass-A with HRC-I, performed a pre-belt ACIS CTI measurement, passed through the belts and began the post-belt ACIS CTI-measurements.
During the next 24 hours, a rapid burster X-ray source (and Chandra's first Target of Opportunity) will be observed with ACIS-S and the HETG HRC observation of G21.5-0.9.
The spacecraft systems continued to operate nominally.
