TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5416 SUBJECT: IPN triangulation of GRB060806 (long, exceptionally bright) DATE: 06/08/07 19:26:08 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 team, D. M. Smith, R. P. Lin, J. McTiernan, R. Schwartz, C. Wigger, W. Hajdas, and A. Zehnder, on behalf of the RHESSI GRB team, K.Yamaoka, M.Ohno, Y.Fukazawa, T.Takahashi, M.Tashiro, Y. Terada, T.Murakami, and K.Makishima on behalf of the Suzaku WAM team, and S. Barthelmy, J. Cummings, N. Gehrels, and H. Krimm, on behalf of the Swift-BAT team, report: This burst was observed by Ulysses, Mars Odyssey, Konus, RHESSI, Suzaku, and Swift-BAT (outside the field of view) at 51821 s. It was long (~120 s) and exceptionally bright (details of the spectrum will be given in a forthcoming GCN Circular). We have triangulated it to an ~ 8 sq. arcmin. error box (3 sigma) whose coordinates are: RA(2000) DEC(2000) 18 h 8 m 34.56 s -20 o 22 ' 49.51 " (CENTER) 18 h 8 m 34.80 s -20 o 24 ' 9.69 " (CORNER) 18 h 8 m 47.14 s -20 o 24 ' 45.83 " (CORNER) 18 h 8 m 22.00 s -20 o 20 ' 53.12 " (CORNER) 18 h 8 m 34.32 s -20 o 21 ' 29.33 " (CORNER) This error box may be improved.
