TITLE: GCN CIRCULAR NUMBER: 6514 SUBJECT: GRB 070612B: Swift XRT position from downlink data DATE: 07/06/12 07:49:35 GMT FROM: Dirk Grupe at PSU/Swift-XRT D. Grupe (PSU), P. Evans (U Leicester), report on behalf of the Swift Team: Swift XRT started observing the afterglow of GRB 070612B (GCN circ 6511) at 07:15:15.59, 3239s after the BAT trigger. We found a bright, uncatalogued, possibly fading source in the XRT data. Using 272 of prompt downlinked data, we find a position RA, Dec 261.7267, -8.7524 which is RA(J2000) = 17 26 54.4 Dec(J2000) = -08 45 08.7 with an uncertainty of 4.7 arcsec (radius, 90% containment). Further analysis of the data will be performed with the ground-processed data.
