TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1709 SUBJECT: Improved IPN error box for GRB021125 DATE: 02/11/26 23:08:11 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley, on behalf of the Ulysses and Mars Odyssey GRB teams, E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB 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, I. Mitrofanov, D. Anfimov, A. Kozyrev, M. Litvak and A. Sanin, on behalf of the HEND/Odyssey GRB team, T. Cline, on behalf of the Ulysses, Odyssey, and Konus GRB teams, and W. Boynton, C. Fellows, K. Harshman, C. Shinohara and R. Starr, on behalf of the GRS/Odyssey GRB team, report: This burst (GCN 1706, 1707) was also observed by Konus. We have triangulated it to an improved, but still preliminary 3 sigma error box whose approximate area is 72 sq. arcmin. and whose coordinates are: RA(2000) DEC(2000) ERROR BOX CENTER: 19 h 47 m 25.93 s 28 o 16 ' 0.45 " ERROR BOX CORNER 1: 19 h 46 m 45.23 s 28 o 8 ' 57.88 " ERROR BOX CORNER 2: 19 h 47 m 33.79 s 28 o 20 ' 50.43 " ERROR BOX CORNER 3: 19 h 47 m 18.08 s 28 o 11 ' 10.45 " ERROR BOX CORNER 4: 19 h 48 m 06.73 s 28 o 23 ' 02.41 " This error box is fully contained within the INTEGRAL error circle and overlaps the previous IPN error box (GCN 1707), but about 10 square arcminutes in this new box are not included in the old one. A map showing the two new triangulation annuli, the INTEGRAL error circle, and the old error box, is being posted to ssl.berkeley.edu/ipn3/021125. This error box may be improved.
