INTEGRAL SPI-ACS GRB team, report:

SGR1806-20 continues to be active in the hard X-ray band, with the most
recent bursts observed on 2004 June 15.  The following is a summary of
all events in 2004 to date which are either confirmed (by imaging or by
triangulation) or suspected to originate from this source.  "Suspected"
means that the event is a short and/or soft spectrum burst, but that it
has not been localized.  Many recent HETE events have been confirmed by Konus
in either triggered or waiting mode data, but not all of them can be
triangulated.  This list, which includes some events previously
mentioned in GCN Circulars, is not meant to be complete.  The data of
all the IPN spacecraft have not been examined exhaustively yet, and in
addition, Earth-blocking and experiment duty cycles prevent many bursts
from being detected.  At this point, we will only issue future GCN's
for exceptional bursts from this source, or exceptionally active
periods.
