The Swift BAT instrument detected GRB 050315 at 20:59:42 UT on 15 March
2005 (Parsons et al 2005, GCN 3094). The observatory executed an automated
slew to the BAT position and the XRT began taking data at 21:01:05.5
UT. The XRT was in Manual state and made observations in Photon Counting
mode. Data were dumped to the ground at about 00:00 UT on 16 March 2005
and a preliminary analysis was performed by the XRT team. We find a bright
uncataloged, rapidly fading X-ray source located at:
RA(J2000) = 20:25:54,
Dec(J2000) = -42:36:0.2
We estimate an uncertainty of about 6 arcseconds. This source is 32
arcseconds from the BAT position reported in GCN 3094.
