TITLE: GCN GRB OBSERVATION REPORT NUMBER: 859 SUBJECT: IPN TRIANGULATION OF GRB001020 DATE: 00/10/23 16:10:50 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 Konus- Wind and NEAR GRB teams, report: Ulysses, Konus-Wind, and NEAR observed this burst at 72065 s. As observed by Ulysses, it had a duration ~30 s, a 25-100 keV fluence of 3.3E-05 erg/cm^2, and a peak flux of 7.4E-06 erg/cm^2 s over 0.25 s. We have triangulated it to a preliminary, 3 sigma, 74 sq. arcmin. error box whose coordinates are: RA(2000) DEC(2000) 18 h 6 m 32.40 s -24 o 45 ' 45.77 " (CENTER) 18 h 5 m 3.22 s -24 o 29 ' 45.04 " (CORNER) 18 h 6 m 30.27 s -24 o 43 ' 33.42 " (CORNER) 18 h 6 m 34.54 s -24 o 47 ' 58.24 " (CORNER) 18 h 8 m 4.61 s -25 o 2 ' 11.39 " (CORNER) This error box may be improved.
