TITLE: GCN CIRCULAR NUMBER: 761 SUBJECT: IPN localization of GRB000801 DATE: 00/08/01 18:26:42 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley, on behalf of the Ulysses GRB team, S. Golenetskii and E. Mazets, on behalf of the Konus-Wind GRB team, and T. Cline, on behalf of the NEAR and Konus-Wind GRB teams, report: Ulysses, Konus, and NEAR observed this burst at 17774 s UT. As observed by Ulysses, it had a duration ~30 s, a 25-100 keV fluence of ~1.7x10^-5 erg/cm^2, and a peak flux over 0.25 s of ~1.3x10^-6 erg/cm^2 s. We have triangulated it to two preliminary, 3 sigma error boxes whose coordinates are: RA(2000) DEC(2000) 6 h 27 m 31.87 s -38 o 40 ' 9.79 " (CENTER) 6 h 27 m 23.28 s -38 o 42 ' 48.54 " (CORNER) 6 h 27 m 31.98 s -38 o 28 ' 57.97 " (CORNER) 6 h 27 m 32.02 s -38 o 51 ' 21.61 " (CORNER) 6 h 27 m 40.45 s -38 o 37 ' 31.22 " (CORNER) OR RA(2000) DEC(2000) 11 h 11 m 46.14 s -9 o 24 ' 43.65 " (CENTER) 11 h 11 m 58.39 s -9 o 25 ' 33.33 " (CORNER) 11 h 11 m 15.51 s -9 o 16 ' 27.89 " (CORNER) 11 h 12 m 16.65 s -9 o 33 ' 1.31 " (CORNER) 11 h 11 m 33.90 s -9 o 23 ' 54.23 " (CORNER) This triangulation result can be improved. In particular, we have used Earth-blocking by BeppoSAX, which did not observe this event, to determine that the first position is the more likely one. However, confirmation will only come when the full Konus data set becomes available. Due to continuing network problems at Goddard, this may require up to 24 hours.
