N. Gehrels (GSFC), J. A. Nousek (PSU), S. Barthelmy (GSFC), D. N. Burrows,
P. Roming (PSU), report on behalf of the Swift team:
The Swift team reported three GRBs earlier today, but has now determined
that all of these triggers (BAT triggers 112977, 112981, and 112982; GCN
Circulars #3155, 3156, 3157, 3158) were due to Vela X-1. The positions
were assigned incorrectly due to attitude errors on the spacecraft. All of
these triggers are being retracted. Swift has not found a true GRB yet today.
