TITLE: GCN GRB OBSERVATION REPORT NUMBER: 730 SUBJECT: GRB000623 DATE: 00/06/24 20:26:17 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 59762 s UT. As observed by Ulysses, it had a duration ~5 s, a 25-100 keV fluence of ~5x10^-6 erg/cm^2, and a peak flux over 0.5 s of ~6x10^-7 erg/cm^2 s. We have localized it to an ~130 sq. arcmin. error box whose preliminary, 3 sigma coordinates are: RA(2000) DEC(2000) 11 h 15 m 41.48 s 10 o 42 ' 2.50 " (CENTER) 11 h 15 m 56.55 s 10 o 41 ' 53.52 " (CORNER) 11 h 14 m 17.45 s 11 o 0 ' 30.38 " (CORNER) 11 h 17 m 4.21 s 10 o 23 ' 34.43 " (CORNER) 11 h 15 m 26.41 s 10 o 42 ' 11.33 " (CORNER) This localization can be improved.
