Therefore the\nbursts can be confidently associated with SGR 1806-20 and not with\nSGR 1808-20 (GCN 2351).\n\nBoth bursts were detected with IBIS/ISGRI in the 15-100 keV range and had\na duration of about 200 ms. Their fluences in the 25-100 keV range were\nabout 2x10-9 ergs cm-2 and 2x10-8 ergs cm-2.\n\nThe TOO INTEGRAL observation of this region (GCN 2372) will continue until\nSeptember 7 at 03:05 UT.\n\nContinued ground-based observations of this region are encouraged.\n\nThis message can be cited.",
