TITLE: GCN CIRCULAR NUMBER: 11275 SUBJECT: Swift-BAT trigger 433953 is not a burst DATE: 10/09/12 19:55:00 GMT FROM: Dirk Grupe at PSU/Swift-XRT D. Grupe, S.D. Barthelmy, and N. Gehrels report on behalf of the Swift team: Using the data set from T-60 to T+240 s from recent telemetry downlinks, we report that BAT trigger #433953 is not a GRB, nor is it astrophysical. It is likely due to a chance coincidence of fluctuations in the rate and image domains.
