behalf of the Swift XRT team:
The Swift BAT instrument detected GRB 050712 at 14:00:27.51 UT on 12 July
2005 (Grupe et al. 2005, GCN 3573). The observatory executed an automated
slew to the BAT position and the XRT began taking data at 14:03:14 UT
(166.1 s after the BAT trigger). The XRT was in Auto state but the source
was not initially bright enough for a successful on-board centroid. In
ground-processed data we find a bright uncataloged, rapidly fading X-ray
source located at:
RA(J2000) = 05:10:47.9,
Dec(J2000) = +64:54:51.5.
We estimate an uncertainty of about 6 arcseconds radius (90%
containment). This source is located 56 arcseconds from the BAT position
in GCN 3573.
