TITLE: GCN CIRCULAR NUMBER: 14786 SUBJECT: Swift Trigger 557466 is not astrophysical DATE: 13/06/06 23:12:34 GMT FROM: Scott Barthelmy at NASA/GSFC S. D. Barthelmy (GSFC) and P.A. Evans (U. Leicester), on behalf of the Swift Team report: Using the BAT data set from T-119 to T+183 sec from recent telemetry downlinks, we report on further analysis of BAT trigger #557466 that the trigger is not due to anything astrophysical. It was a chance coincidence of noise in the image domain and a known source. Analysis of 1 ks of XRT reveals no source in or near the BAT error circle.
