• GCN notice #905
  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 54229 seconds. As observed by Ulysses, it had a duration of approximately 8. seconds, and a 25-100 keV peak flux of approximately 9.1E-07 erg/cm2 s over .25 seconds.
  We have triangulated it to two alternate, preliminary,3 sigma error boxes each with approximate area 101. sq. arcmin. whose coordinates are:

  There is a chance that the ambiguity can be resolved by further processing within about 8 hours.
