TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2181 SUBJECT: IPN triangulation of GRB030429 (annulus) DATE: 03/04/30 17:03:02 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-Wind observed this GRB at 24688 seconds. As observed by Ulysses, it had a duration of approximately 5 seconds, a 25-100 keV fluence of approximately 1.5E-06 erg/cm2, and a peak flux of approximately 7.4E-07 erg/cm2 s over 0.25 seconds. We have triangulated it to a preliminary annulus centered at RA, Decl(2000)= 332.879, -37.786 degrees, whose radius is 49.400 +/- 0.042 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.
