GCN Circular 6496
GRB 070611; Swift-XRT position M.C. Stroh, J. A. Kennea & C. Pagani (PSU) report on behalf of the Swift-XRT team: We have analyzed the first 1.8 ks of prompt downlinked data for GRB 070611 (trigger=282003, GCN Circ. 6494). Because of an Earth limb constraint, the spacecraft did not slew promptly to the BAT position and the XRT observations started 3.3 ks since the BAT Trigger. In the BAT error circle we find an uncatalogued source at position RA, Dec 1.9912, -29.7568 which is RA(J2000) = 00 07 57.9 Dec(J2000) = -29 45 24.3 with an uncertainty of 5.1 arcsec (radius, 90% containment). The XRT position is 15arcsec from the BAT on board position (GCN Circ. 6494), within the BAT error circle. We are waiting for additional downlinked data to assess the fading behavior of the proposed X-ray afterglow. This circular is an official product of the Swift-XRT team.
