TITLE: GCN GRB OBSERVATION REPORT NUMBER: 642 SUBJECT: IPN error box for GRB000418 DATE: 00/04/20 17:07:27 GMT FROM: Kevin Hurley at UCBerkeley/SSL K. Hurley, on behalf of the Ulysses GRB team, and T. Cline and E. Mazets, on behalf of the NEAR and KONUS-Wind teams, report: Ulysses, NEAR, and KONUS observed GRB000418 at 35590 s UT. As observed by Ulysses, this burst had a duration of ~30 s, and a 25-100 keV fluence of ~1.3x10^-5 erg/cm^2. We have triangulated it to an ~ 35 sq. arcmin. error box at the following 3 sigma, preliminary position: RA(2000) DEC(2000) 12 h 25 m 21.17 s 20 o 5 ' 3.61 " (CENTER) 12 h 25 m 33.03 s 20 o 4 ' 17.15 " (CORNER) 12 h 24 m 49.69 s 20 o 13 ' 17.39 " (CORNER) 12 h 25 m 52.50 s 19 o 56 ' 49.93 " (CORNER) 12 h 25 m 9.30 s 20 o 5 ' 50.00 " (CORNER) This position can be refined.
