TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1876 SUBJECT: IPN triangulation of GRB030220 (annulus) DATE: 03/02/21 18:00:55 GMT FROM: Kevin Hurley at UCBerkeley/SSL <khurley@sunspot.ssl.berkeley.edu> K. Hurley and T. Cline, on behalf of the Ulysses and HETE GRB teams, A. von Kienlin, G. Lichti, and A. Rau, on behalf of the INTEGRAL SPI-ACS GRB team, and 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, report: Ulysses, INTEGRAL (SPI-ACS), and HETE-FREGATE (H2601) observed this burst at 58364 seconds. As observed by Ulysses, it had a duration of approximately 50 seconds, a 25-100 keV fluence of approximately 9.7E-06 erg/cm2, and a peak flux of approximately 4.9E-07 erg/cm2 s over 0.50 seconds. We have triangulated it to a preliminary annulus centered at RA, Decl (2000)=170.434, +41.934 degrees, whose radius is 52.468 +/- 0.065 degrees (3 sigma). This annulus may be constrained and/or improved, but as this event was not observed by Mars Odyssey, a small error box cannot be obtained for it.
