Hurley, on behalf of the Ulysses and Konus GRB team,\n\nHelicon-Coronas-F also observed two SGR bursts (GCN 2414, 2415),\nfirst at 03:27:04:070 UT (12424.070 s) and second one at 03:27:56:172 UT \n(12476.172s).\nKonus-Wind - Helicon-Coronas-F triangulation gives the\nannulus centered at RA(2000) = 344.822 deg, Dec(2000) = 0.740 deg, and\nradius of 74.130 +/- 0.292 deg (3 sigma) (the distance between Wind and\nCoronas-F was only 1 light second).\n\nThis annulus intersects the Ulysses-Konus annulus (GCN 2414) to\nform two error boxes, one of which may be eliminated by the Konus\necliptic latitude response.  The resulting error box has an approximate\narea of 40 sq. arcmin.  Its coordinates are:\n\n\t\t\tRA(2000)\tDEC(2000)\nERROR BOX CENTER:\t272.106\t\t-20.647\nERROR BOX CORNER1:\t271.897\t\t-21.447\nERROR BOX CORNER2:\t272.310\t\t-19.793\nERROR BOX CORNER3:\t272.317\t\t-19.850\nERROR BOX CORNER4:\t271.905\t\t-21.505\n\n\nThis error box includes the position of SGR 1806-20.\n\nThe first burst contains a precursor with a duration ~0.100 s and a main\npulse which had a duration ~0.110 s (total duration 0.210 s).\nThe second burst had a duration of approximately 0.380 s .\n\nThe spectrum of the first burst can be well-described by OTTB model\ndN/dE ~ E^-1 exp(-E/E0) with E0 = 13.4 +/- 0.7 keV.\n\nThe fluences are:\n\t\t13-200 keV\t\t25-100 keV\n1st burst: 3.15 x 10^-6 erg/cm2\t\t1.3 x 10^-6 erg/cm2\n2nd burst: 1.7 x 10^-6 erg/cm2\t\t7.0 x 10^-7 erg/cm2\n\nThe peak fluxes are:\n1st burst: 4.0 x 10^-5 erg/cm2 s (over 0.008 s)\n2nd burst: 1.5 x 10^-5 erg/cm2 s (over 0.064 s)",
