TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1692 SUBJECT: IPN triangulation of GRB021113 (=H2449; annulus) DATE: 02/11/14 18:40:49 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley and T. Cline, on behalf of the Ulysses, Konus, and HETE GRB teams, E. Mazets and S. Golenetskii, on behalf of the Konus-Wind 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 and Konus-Wind also observed this GRB (HETE 2449, GCN 1686). We have triangulated it to a preliminary annulus centered at RA, Decl(2000)= 1.104, -35.210 degrees, whose radius is 78.410 +/- 0.078 degrees (3 sigma ). This intersects the WXM error box given in GCN 1686 at four points, and reduces its area by about 30%. The intersection points are: RA(2000) DECL(2000) 1 h 32 m 44.80 s 40 o 26 ' 18.72 " 1 h 33 m 46.40 s 40 o 32 ' 15.63 " 1 h 35 m 00.19 s 40 o 27 ' 32.32 " 1 h 33 m 28.89 s 40 o 23 ' 31.68 " This annulus can be improved, but as Mars Odyssey was recovering from safe mode, a small error box cannot be derived for it. A map will be posted shortly at ssl.berkeley.edu/ipn3/021113.
