TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1726 SUBJECT: IPN detection of renewed activity from SGR1806-20 DATE: 02/12/07 20:31:06 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley, on behalf of the Ulysses GRB team, E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, and T. Cline, on behalf of the Ulysses and Konus GRB teams, report: Ulysses has observed 5 short, intense SGR-like bursts on December 5 and 6. So far, one of these events has also been reported by Konus-Wind, and the center line of its triangulation annulus passes ~10" from the position of SGR1806-20, and >5 degrees from that of SGR1900+14. We conclude that this burst indeed originates from SGR1806-20. As there is a hint of continuing activity from SGR1900+14, we cannot at this point be certain of the origin of the other events, but will attempt to determine this as soon as possible. The times of these events were: December 5, 2002: 02828 s * 12925 s * 32992 s ** 72064 s * December 6, 2002: 63291 s * * crossing time at Ulysses; subtract ~418 s to get Earth-crossing time if the source was SGR1806-20 ** event also observed by Konus; this is the Earth-crossing time
