TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1791 SUBJECT: IPN triangulation of GRB030102A (large error box) DATE: 03/01/08 19:17:26 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 56870 seconds. As observed by Ulysses, it had a duration of approximately 30 seconds, a 25-100 keV fluence of approximately 1.2E-05 erg/cm2, and a peak flux of approximately 5.0E-01 erg/cm2 s over 0.5 seconds. We have triangulated it to a preliminary annulus centered at RA, Decl(2000)= 181.922, 37.602 degrees, whose radius is 78.343 +/- .036 degrees (3 sigma ). The Konus ecliptic latitude response constrains the arrival direction to a band between ecliptic latitudes 55 and 75 degrees, that is, to those portions of the annulus north of RA, Decl= 283, +32 degrees, and 2, +64 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.
