TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1782 SUBJECT: GRB021226 DATE: 03/01/01 20:11:34 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley, on behalf of the Ulysses GRB team, E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, A. von Kienlin, G. Lichti, and A. Rau, on behalf of the INTEGRAL SPI-ACS GRB team, T. Cline, on behalf of the Ulysses, Konus, and Odyssey GRB teams, I. Mitrofanov, D. Anfimov, A. Kozyrev, M. Litvak and A. Sanin, 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, and D. M. Smith, R. P. Lin, J. McTiernan, R. Schwartz, C. Wigger, W. Hajdas, and A. Zehnder, on behalf of the RHESSI GRB team, report: Konus, RHESSI, and Mars Odyssey (HEND and GRS) also observed this burst (GCN 1779, 1780). We have triangulated it to a preliminary annulus centered at RA, Decl (2000)=43.742, 15.925 degrees, whose radius is 88.444 +/- 0.115 degrees (3 sigma). This annulus can be refined and constrained, but as this burst was not observed by Ulysses, a small error box cannot be obtained for it.
