GCN Circular 8393
J. R. Cummings (NASA/UMBC/CRESST) on behalf of the Swift team: We have analyzed BAT event data from trigger 332287 (Lyons et al. GCN# 8392). We cannot improve the weak peak in the image domain at the position of the source that was reported onboard. We see a weak peak from Cyg X1 in an image at the trigger time, and a weak peak in the maskweighted lightcurve at the position of Cyg X1. We conclude that the trigger was due to a weak burst from Cyg X1 and a chance peak in the image domain, and not from a GRB.
