TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1617 SUBJECT: IPN triangulation of GRB021008 DATE: 02/10/10 18:09:38 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, and T. Cline, on behalf of the Ulysses and Konus GRB teams, report: Ulysses and Konus observed this burst at 25250 s. As observed by Ulysses, it had a duration ~30 s, a 25-100 keV fluence of 8.5E-5 erg/cm2, and a peak flux over 0.5 s of 1.3E-5 erg/cm2 s. We have triangulated it to a preliminary annulus centered at RA, Decl (2000)=175.616, 36.839 degrees, whose radius is 14.065+/-0.126 degrees. This annulus can be constrained further, but at this point it is not clear whether the event was observed by Mars Odyssey, and thus whether an error box can be derived for it.
