TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2237 SUBJECT: IPN triangulation of GRB030519B=H2716 (small error box) DATE: 03/05/20 16:32:42 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley and T. Cline, on behalf of the Ulysses and HETE GRB teams, G. Ricker, J-L Atteia, N. Kawai, D. Lamb, S. Woosley, J. Doty, R. Vanderspek, J. Villasenor, G. Crew, G. Monnelly, N. Butler, J.G. Jernigan, A.

Tavenner, T. Donaghy, M. Boer, J-F Olive, and J-P Dezalay, on behalf of the HETE GRB team, and D. M. Smith, R. P. Lin, J. McTiernan, R. Schwartz, C. Wiggger, W. Hajdas, and A. Zehnder, on behalf of the RHESSI GRB team, report: Ulysses and RHESSI also observed this burst (GCN 2235), As observed by Ulysses, it had a duration of approximately 12 seconds, a 25-100 keV fluence of approximately 2.9E-05 erg/cm2, and a peak flux of approximately 4.3E-06 erg/cm2 s over 0.50 seconds. We have triangulated it to a preliminary annulus centered at RA, Decl(2000)= 331.653, -35.097 degrees, whose radius is 71.871 +/- 0.018 degrees (3 sigma). This annulus intersects the HETE WXM error box and reduces its area to ~35 square arcminutes. The coordinates of the IPN/WXM error box are: ERROR BOX CENTER : 241.152 -33.473 ERROR BOX CORNER 1: 241.020 -33.623 ERROR BOX CORNER 2: 241.073 -33.621 ERROR BOX CORNER 3: 241.231 -33.325 ERROR BOX CORNER 4: 241.284 -33.323 This error box may be improved.
