  W. Boynton, C. Fellows, K. Harshman, and C. Shinohara, on behalf of the GRS/Odyssey GRB team, report:
  Ulysses, Mars Odyssey - HEND, Konus - Wind, and BeppoSAX observed this GRB at 58815 s. As observed by Ulysses, it had a duration of ~10 seconds, a 25-100 keV fluence of ~3 x10^-6 erg/cm2, and a peak flux of ~10^-6 erg/cm2 s over 0.25 s.
  We have triangulated it to a preliminary, 3 sigma error box with approximate area 20 square arcminutes whose coordinates are:

      RA(2000)                 DEC(2000)
    0 h 59 m 39.00 s     -7 o  6 '  25.23 "  (CENTER)
    0 h 59 m 27.18 s     -7 o  4 '  50.14 "  (CORNER)
    1 h  0 m  5.32 s     -7 o  6 '  18.07 "  (CORNER)
    0 h 59 m 12.74 s     -7 o  6 '  32.61 "  (CORNER)
    0 h 59 m 50.83 s     -7 o  8 '   0.36 "  (CORNER)
  

  This error box can be improved.
