TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2404 SUBJECT: IPN triangulation of GRB030922B (large error box) DATE: 03/09/26 00:46:00 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley and T. Cline, on behalf of the Ulysses, Konus, and Mars Odyssey GRB teams, E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, I. Mitrofanov, S. Charyshnikov, V. Grinkov, A. Kozyrev, M. Litvak, and A. Sanin, on behalf of the HEND-Odyssey GRB team, and W. Boynton, C. Fellows, K. Harshman, C. Shinohara and R. Starr, on behalf of the GRS/Odyssey GRB team, report: Ulysses, Konus-Wind, and Mars Odyssey-HEND and GRS, observed this GRB at 66648 seconds. As observed by Ulysses, it had a duration of approximately 18 seconds, a 25-100 keV fluence of approximately 1.2E-05 erg/cm2, and a peak flux of approximately 1.5E-06 erg/cm2 s over 0.50 seconds. We have triangulated it to a preliminary, 3 sigma error box whose approximate area is 2000 sq. arcmin. and whose coordinates are: RA(2000) DEC(2000) ERROR BOX CENTER: 1 h 58 m 54.54 s -20 o 04 ' 28.12 " ERROR BOX CORNER 1: 2 h 01 m 21.28 s -24 o 11 ' 15.54 " ERROR BOX CORNER 2: 2 h 01 m 04.85 s -24 o 12 ' 57.87 " ERROR BOX CORNER 3: 1 h 56 m 43.51 s -15 o 56 ' 04.33 " ERROR BOX CORNER 4: 1 h 56 m 28.55 s -15 o 57 ' 34.72 " Only slight improvements to this error box are expected.
