TITLE: GCN CIRCULAR NUMBER: 13173 SUBJECT: Swift trigger 518853 is most likely GX 301-2 DATE: 12/03/29 18:24:14 GMT FROM: Scott Barthelmy at NASA/GSFC S. D. Barthelmy (GSFC) and T. Sakamoto (GSFC/UMBC) on behalf of the Swift team: Swift trigger 518853 (reported in GCN 13166) is not due to a new galactic transient, nor is it a GRB. This trigger was the result of a large roll angle error and an on-board misidentification of GX 301-2 as IGR12349-6434.
