TITLE: GCN CIRCULAR NUMBER: 776 SUBJECT: IPN localization of GRB000820 DATE: 00/08/21 18:13:56 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: This burst was observed by Ulysses, Konus-Wind, and NEAR at 31075 s. As observed by Ulysses, it had a duration ~30 s, a 25-100 keV fluence ~4x10^-5 erg/cm^2, and a peak flux over 0.5 s of 2.7 x 10^-6 erg/cm^2 s. We have triangulated it to a preliminary, 3 sigma error box whose area is ~200 sq. arcmin. and whose coordinates are: RA(2000) DEC(2000) 8 h 57 m 20.46 s -8 o 49 ' 12.10 " (CENTER) 8 h 57 m 54.47 s -8 o 44 ' 9.72 " (CORNER) 8 h 55 m 11.33 s -8 o 57 ' 53.17 " (CORNER) 8 h 59 m 22.50 s -8 o 41 ' 35.49 " (CORNER) 8 h 56 m 45.97 s -8 o 54 ' 19.51 " (CORNER) This error box may be refined considerably.
