  K. Hurley, on behalf of the Ulysses GRB team, C. Guidorzi, E. Montanari, and F. Frontera, on behalf of the BeppoSAX GRBM team, and T. Cline, on behalf of the NEAR GRB team, report:
  Ulysses, BeppoSAX GRBM, and NEAR observed this burst at 53479 s UT. As observed by Ulysses, it had a duration of approx. 7 s, a 25 - 100 keV fluence of approx. 1E-5 erg/cm2, and a peak flux over 0.5 s of approx. 2E-6 erg/cm2 s. Due to an unfavorable arrival direction, it can only be localized to an approx. 6 degree by 20 arcmin. error box whose coordinates are:
