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
