TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1713 SUBJECT: IPN triangulation of GRB021115 (annulus) DATE: 02/11/28 01:11:01 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 Ulysses and Konus GRB teams, report: Ulysses, RHESSI, and Konus-Wind observed this GRB at 48785 seconds. It had a duration of approximately 60 seconds, a 25-100 keV fluence of approximately 7.6E-06 erg/cm2, and a peak flux of approximately 5.0E-07 erg/cm2 s over 0.50 seconds. We have triangulated it to a preliminary annulus centered at RA, Decl(2000)= 1.348, -35.197 degrees, whose radius is 22.531 +/- 1.488 degrees (3 sigma ). This annulus may be constrained and/or improved, but as the event was not observed by Mars Odyssey, a small error box cannot be derived for it.
