TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2125 SUBJECT: IPN triangulation of GRB030403 (annulus) DATE: 03/04/09 22:00:22 GMT FROM: Kevin Hurley at UCBerkeley/SSL <khurley@sunspot.ssl.berkeley.edu> K. Hurley, on behalf of the Ulysses GRB team, E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, 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. Levine, F. Martel, E. Morgan, G. Prigozhin, J. Braga, R. Manchanda, G. Pizzichini, Y. Shirasaki, C. Graziani, M. Matsuoka, T. Tamagawa, K. Torii, T. Sakamoto, A. Yoshida, E. Fenimore, M. Galassi, T. Tavenner, T. Donaghy, M. Boer, J-F Olive, and J-P Dezalay, on behalf of the HETE GRB team, A. von Kienlin, G. Lichti, and A. Rau, on behalf of the INTEGRAL SPI-ACS GRB team, and T. Cline, on behalf of the Ulysses and Konus GRB teams, report: Ulysses, Konus-Wind, INTEGRAL (SPI-ACS), and HETE - FREGATE (UBID 10896) observed this GRB at 13066 seconds. As observed by Ulysses, it had a duration of approximately 30 seconds, a 25-100 keV fluence of approximately 5.1E-06 erg/cm2, and a peak flux of approximately 5.2E-07 erg/cm2 s over 0.25 seconds. We have triangulated it to a preliminary annulus centered at RA, Decl(2000)= 157.362, 40.758 degrees, whose radius is 21.165 +/- 0.172 degrees (3 sigma ). This annulus may be constrained and/or improved, but as the event was not observed by Mars Odyssey, a small error box cannot be derived for it.
