TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1792 SUBJECT: IPN triangulation of GRB030102B (portion of annulus) DATE: 03/01/08 19:49:06 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 83938 seconds. As observed by Ulysses, it had a duration of approximately 8 seconds, a 25-100 keV fluence of approximately 4.2E-06 erg/cm2, and a peak flux of approximately 8.9E-7 erg/cm2 s over 0.5 seconds. We have triangulated it to a preliminary annulus centered at RA, Decl(2000)= 1.888, -37.630 degrees, whose radius is 14.843 +/- .137 degrees (3 sigma ). The Konus ecliptic latitude response constrains the arrival direction to a band between ecliptic latitudes -20 and -40 degrees, that is, to those portions of the annulus north of RA, Decl= 349, -49 and 20, -35 degrees. This annulus can be improved, but as the event was not observed by Mars Odyssey, a small error box cannot be derived for it.
