TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1863 SUBJECT: IPN triangulation of GRB030206 (annulus) DATE: 03/02/11 18:43:32 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, D. M. Smith, R. P. Lin, J. McTiernan, R. Schwartz, C. Wigger, W. Hajdas, and A. Zehnder, on behalf of the RHESSI GRB team, and T. Cline, on behalf of the Konus and Ulysses GRB teams, report: Konus and RHESSI observed this burst at 39632 s. Its duration was ~0.1 s. We have triangulated it to a preliminary annulus centered at RA, Decl (2000)= 132.776, +22.248 degrees, with radius 59.979 +/- 1.914 degrees (3 sigma). In addition, the Konus ecliptic latitude response restricts the arrival direction to the south ecliptic hemisphere, that is, to those portions of the annulus below RA, Dec =69.5, +22.1 degrees, and RA, Dec= 186.5, -2.8 degrees. As this annulus does not include any of the known soft gamma repeaters, but does intersect the galactic plane, this burst is likely, although not certain, to be a short/hard GRB. It will not be possible to derive a small error box for this burst.
