on behalf of the Swift XRT team:
The Swift BAT instrument found Triggers 114298/114299 (possibly GRB 050410)
at 12:14:25 UT on 10 April 2005. The target was within the Swift Earth
constraint and the observatory executed a delayed automated slew to the BAT
position at 12:44:20. The XRT began taking data at 12:46:27 UT, about 32
minutes after the burst. The afterglow was too faint for the XRT to
produce an on-board centroid. Ground processing shows a faint uncataloged
X-ray source located at:
RA(J2000) = 05:59:12.9
Dec(J2000) = +79:36:9.2
We estimate an uncertainty of about 5 arcseconds radius (90%
containment). This source is located 38 arcseconds from the BAT position
for Trigger 114299.
