TITLE: GCN GRB OBSERVATION REPORT NUMBER: 852 SUBJECT: IPN TRIANGULATION OF GRB 001017 DATE: 00/10/18 21:05:30 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 80347 seconds. As observed by Ulysses, it had a duration of approximately 10. seconds, a 25-100 keV fluence of approximately 3.6E-06 erg/cm2, and a peak flux of approximately 1.0E-06 erg/cm2 s over .25 seconds We have triangulated it to a preliminary, 3 sigma error whose approximate area is 1300 sq. arcmin. and whose coordinates are: ERROR BOX CENTER: 18 h 8 m 41.99 s -2 o 59 ' 37.61 " ERROR BOX CORNER 1: 18 h 7 m 50.30 s -2 o 59 ' 25.43 " ERROR BOX CORNER 2: 18 h 12 m 58.86 s -3 o 53 ' 2.79 " ERROR BOX CORNER 3: 18 h 4 m 38.90 s -2 o 8 ' 12.27 " ERROR BOX CORNER 4: 18 h 9 m 33.83 s -2 o 59 ' 50.93 " This error box may be improved
