TITLE: GCN GRB OBSERVATION REPORT NUMBER: 759 SUBJECT: IPN localization of GRB000730B DATE: 00/07/31 16:30:13 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley, on behalf of the Ulysses GRB team, T. Cline, on behalf of the Konus-Wind and NEAR GRB teams, and E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, report: Ulysses, Konus-Wind, and NEAR observed this burst at 50427 s UT. As observed by Ulysses, it had a duration of ~10 s, a 25-100 keV fluence of ~1.5x10^-5 erg/cm^2, and a peak flux over 0.5 s of 2.4x10^-6 erg/cm^2 s. We have triangulated this burst to two preliminary, 3 sigma error boxes whose areas are ~65 sq. arcmin. each, and whose coordinates are: RA(2000) DEC(2000) 4 h 44 m 52.18 s 35 o 26 ' 0.98 " (CENTER) 4 h 43 m 20.48 s 35 o 1 ' 20.71 " (CORNER) 4 h 45 m 0.15 s 35 o 26 ' 28.23 " (CORNER) 4 h 44 m 44.21 s 35 o 25 ' 33.76 " (CORNER) 4 h 46 m 27.00 s 35 o 51 ' 11.65 " (CORNER) OR RA(2000) DEC(2000) 8 h 25 m 45.53 s 60 o 3 ' 46.10 " (CENTER) 8 h 29 m 50.81 s 60 o 8 ' 47.57 " (CORNER) 8 h 25 m 36.30 s 60 o 2 ' 32.33 " (CORNER) 8 h 25 m 54.77 s 60 o 4 ' 59.81 " (CORNER) 8 h 21 m 35.82 s 59 o 58 ' 8.41 " (CORNER) These error boxes may be improved; in particular, it may be possible to determine which is the correct box within a few hours.
