TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1814 SUBJECT: IPN triangulation of GRB030115B (annulus) DATE: 03/01/15 15:58:36 GMT FROM: Kevin Hurley at UCBerkeley/SSL 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) observed this burst at 23070 s. As observed by Ulysses, it had a duration of approximately 100 seconds, a 25-100 keV fluence of approximately 1.2E-05 erg/cm2, and a peak flux of approximately 1.0E-06 erg/cm2 s over 0.25 seconds. We have triangulated it to a preliminary annulus centered at RA, Dec (2000)= 0.310, -38.800 degrees, whose radius is 43.532 +/- 0.031 degrees. This annulus may be improved and/or constrained.
