| During the last week the observing schedule was replanned to include
an observation of GRB 050509b approved as a fast turn-around Target Of
Opportunity (TOO) on May 8. Loads were replanned and uplinked on Mar
10. Observations of KS 1731-260 and 9 Sgr were impacted by the TOO and
will be rescheduled for a later load. A second fast TOO was approved
on May 11 to observe a high redshift blazar and loads were replanned
and uplinked on May 12 for observation on May 13. The targets
MACS0011.7-1523, PSS2322+1944, SDSS J0005-0006 and MACSJ0159.0-3412
were impacted and will be observed in a later load.
During a routine command load uplink on May 12 a ground system anomaly resulted in the uplink of an unexpected memory load to OBC-B. There was no operational impact from the uplink. Following checkout of the ground system and the development of a new ground monitor procedure, operations were continued in parallel with an investigation of the ground system problem. The OBC-B memory load was cleared with a real-time procedure on May 13. A Chandra media telecon was held on May 10 to present a press release describing a long observation of the Orion Nebula. The data allowed the study the X-ray behavior of young Sun-like stars with ages between 1 and 10 million years and the discovery that these young stars produce violent X-ray outbursts that are much more frequent and energetic than seen from the Sun.
