TITLE: GCN CIRCULAR NUMBER: 855 SUBJECT: IPN TRIANGULATION OF GRB001019 DATE: 00/10/20 21:25:28 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, NEAR, and KONUS-WIND observed this GRB at 86375 seconds. As observed by Ulysses, it had a duration of approximately 10. seconds, a 25-100 keV fluence of approximately 7.3E-06 erg/cm2, and a peak flux of approximately 2.0E-06 erg/cm2 s over 0.25 seconds We have triangulated it to a preliminary, 3 sigma error whose approximate area is 26. sq. arcmin. and whose coordinates are: RA(2000) DEC(2000) ERROR BOX CENTER: 17 h 11 m 44.08 s 35 o 20 ' 13.51 " ERROR BOX CORNER 1: 17 h 11 m 35.00 s 35 o 19 ' 45.73 " ERROR BOX CORNER 2: 17 h 12 m 5.56 s 35 o 14 ' 18.33 " ERROR BOX CORNER 3: 17 h 11 m 22.60 s 35 o 26 ' 8.49 " ERROR BOX CORNER 4: 17 h 11 m 53.16 s 35 o 20 ' 41.28 " This error box may be improved
