The following is a summary of all the known bursts which originated, or
are likely to have originated, from SGR1806-20 between July 12 and
August 5, 2003. This is based on the IPN and HETE data available to us
at this time. In the table below, "LOCALIZED" means either an IPN
annulus, a HETE WXM one-dimensional localization, or a HETE WXM
two-dimensional localization. In those cases where there is no
localization, the bursts are short-duration, soft-spectrum events, all
the data for which are consistent with an origin from SGR1806-20.
Still other short events have been detected, one as recently as August
5, but their origin remains uncertain at this time.
