GCN Circular 1665
K. Hurley and T. Cline, on behalf of the Ulysses GRB team, and E. Mazets and S. Golenetskii, on behalf of the Helicon-Coronas GRB team, report: Ulysses and Helicon observed this burst at 21837 s. Based on the data available so far, its duration (as observed by Helicon) was ~0.1 s and its 25-100 keV fluence (as observed by Ulysses) was ~ 1.2E-6 erg/cm2. We have triangulated it to a preliminary annulus centered at RA, Decl(2000)=359.608, -35.426 degrees, whose radius is 81.708 +/- 0.032 degrees (3 sigma). As the center line of this annulus passes within 0.018 degrees of SGR1900+14, we conclude that this burst originated from that source. Previous bursts from SGR1900+14 were observed by the IPN on October 10, 22 and 29 2002 (GCN 1643, 1655, 1664).
