TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5407 SUBJECT: IPN triangulation of GRB060805B DATE: 06/08/06 23:54:48 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley and T. Cline, on behalf of the Ulysses, Mars Odyssey, and Konus GRB teams, I. Mitrofanov, A. Kozyrev, M. Litvak, A. Sanin, V. Tret'yakov and A. Parshukov, on behalf of the HEND-Odyssey GRB team, W. Boynton, C. Fellows, K. Harshman, C. Shinohara and R. Starr, on behalf of the GRS-Odyssey GRB team, S. Golenetskii, E. Mazets, V. Pal'shin, and D. Frederiks on behalf of the Konus-Wind teams, D. M. Smith, R. P. Lin, J. McTiernan, R. Schwartz, C. Wigger, W. Hajdas, and A. Zehnder, on behalf of the RHESSI GRB team, and A. von Kienlin, G. Lichti, and A. Rau, on behalf of the INTEGRAL SPI-ACS GRB team, report: Ulysses, Mars Odyssey, Konus, RHESSI, and INTEGRAL (SPI-ACS) observed this very intense, 8 s long burst at 52035 s. Spectral information will be given in a forthcoming GCN Circular. We have triangulated it to an ~ 46 sq. arcmin. error box (3 sigma), whose coordinates are RA(2000) DEC(2000) 18 h 10 m 01.78 s 58 o 08 ' 47.67 " (CENTER) 18 h 09 m 36.85 s 58 o 00 ' 55.18 " (CORNER) 18 h 09 m 47.45 s 57 o 57 ' 22.44 " (CORNER) 18 h 10 m 16.89 s 58 o 20 ' 22.15 " (CORNER) 18 h 10 m 27.16 s 58 o 16 ' 42.85 " (CORNER) This error box may be improved.
