Schady (MSSL), report on behalf of the Swift XRT team:

The Swift BAT instrument detected a GRB at 15:58:48 UT on 6th April 2005 (GCN Circ 3161). The observatory executed an automated slew to the BAT position and the XRT began taking data at 16:00:15 UT.  The XRT was in Auto state but was not able to centroid on the afterglow due to low source brightness. From downlinked data we find a uncataloged, fading X-ray source located at:

RA(J2000) = 2:17:52.4,
Dec(J2000) = -50:11:18.9.

We estimate an uncertainty of about 5 arcseconds.
