TITLE: GCN CIRCULAR NUMBER: 11101 SUBJECT: Swift-BAT trigger 431756 is not a burst DATE: 10/08/15 22:05:55 GMT FROM: Scott Barthelmy at NASA/GSFC S. D. Barthelmy (GSFC), S. R. Oates (UCL-MSSL) and C. J. Saxton (UCL-MSSL) report on behalf of the Swift Team: At 21:48:41 UT (15-Aug-2010), Swift-BAT triggered (#431756) on a spurious source on the sky while the star tracker had lost lock. As such, the source in the image domain did not match anything in the on-board catalog. This is not a gamma-ray burst. [GCN OPS NOTE(15aug10): Per author's request, the "15-Mar-2010" was changed to "15-Aug-2010". We thank E.Winter bringing this mistake to our attention.]
