report on behalf of the Swift XRT team:
GRB 050326 was discovered by the Swift BAT instrument at 09:53:55 UT today
(Markwardt et al. 2005, GCN 3143). The burst was within the Swift Earth
constraint and observations were delayed by nearly an hour. When the XRT
observed the field at 10:48:13 UT, there was no afterglow strong enough for
an on-board centroid determination (which is normal when we observe this
long after the burst). Unfortunately, this burst occurred during the daily
6 to 7 hour period when Swift is out of contact with the ground station, so
we cannot perform ground analysis to search for an X-ray afterglow until
about 19:00 UT. We will issue an updated GCN Circular once we can process
those data.
