TITLE: GCN CIRCULAR NUMBER: 10947 SUBJECT: IPN triangulation of GRB 100707A DATE: 10/07/08 21:49:15 GMT FROM: Valentin Pal'shin at Ioffe Inst K. Hurley and J. Goldsten, on behalf of the MESSENGER GRNS GRB team, S. Golenetskii, R. Aptekar, E. Mazets, V. Pal'shin, D. Frederiks, P. Oleynik, M. Ulanov, D. Svinkin and T. Cline on behalf of the Konus-Wind team, V. Connaughton, M.S. Briggs, and C.A. Meegan on behalf of the Fermi GBM team, and K. Yamaoka, M. Ohno, Y. Fukazawa, T. Takahashi, M. Tashiro, Y. Terada, T. Murakami, K. Makishima, and Y. Hanabata on behalf of the Suzaku-WAM team, report: The long bright GRB 100707A, observed by Fermi/GBM at 00:46:38.99 UT (Wilson-Hodge & Foley, GCN 10944) and Fermi/LAT (Pelassa & Pesce-Rollins, GCN 10945), has also been detected by Suzaku (WAM), Konus-Wind, and MESSENGER (GRNS) so far. We have triangulated it to a preliminary 3 sigma error box whose coordinates are: ----------------------------------------------- RA(2000), deg Dec(2000), deg ----------------------------------------------- Center: 358.019 (23h 52m 05s) -8.658 (-08d 39' 29") Corners: 358.562 (23h 54m 15s) -11.226 (-11d 13' 32") 358.773 (23h 55m 05s) -11.654 (-11d 39' 14") 357.369 (23h 49m 29s) -5.832 (-05d 49' 56") 357.116 (23h 48m 28s) -5.295 (-05d 17' 42") ----------------------------------------------- The error box area is 0.660 sq. deg This error box may be improved. The GBM position (Wilson-Hodge & Foley, GCN 10944) is 7.2 deg from the center of the box.
