TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2411 SUBJECT: IPN triangulation of GRB031004B (annulus) DATE: 03/10/08 01:17:24 GMT FROM: Kevin Hurley at UCBerkeley/SSL <khurley@sunspot.ssl.berkeley.edu> K. Hurley and T. Cline, on behalf of the Ulysses, Mars Odyssey, and Konus-Wind GRB teams, I. Mitrofanov, S. Charyshnikov, V. Grinkov, 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, E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, and A. von Kienlin, G. Lichti, and A. Rau, on behalf of the INTEGRAL SPI-ACS GRB team, report: Mars Odyssey - HEND, Konus - Wind, and INTEGRAL - SPI-ACS observed this 10 s long event at 76450 s. We have triangulated it to a preliminary annulus centered at RA, Decl (2000) = 333.894, -15.273 degrees, whose radius is 48.278 +/- 0.491 degrees (3 sigma). In addition, the Konus ecliptic latitude response limits the arrival direction to ecliptic latitudes between +25 and +75 degrees, that is, to those portions of the annulus north of RA, Decl. = 288, +3 degrees and 359, +27 degrees. This annulus may be constrained and/or improved, but as this event was not observed by Ulysses, a small error box cannot be obtained for it.
