R. M. Kippen on behalf of the BATSE GRB Team, T. Cline and E.
Mazets, on behalf of the NEAR and KONUS-WIND GRB Teams, and
F. Frontera, C. Guidorzi and E. Montanari, on behalf of the
BeppoSAX GRBM Team, report:

Ulysses, BATSE, Konus, NEAR, and the BeppoSAX GRBM observed
GRB000429 (BATSE 8087) at 36430 s UT.  As observed by Ulysses,
this burst had a duration of ~50 s, a 25-100 keV fluence of
~4 x 10^-6 erg/cm^2, and a 0.25 s peak flux of ~6 x 10^-7 erg/
cm^2 s.  We have localized this burst to a preliminary 3 sigma
error box with an area of ~90 sq. arcmin with the following
coordinates:

    RA(2000)                 DEC(2000)
  6 h 33 m 20.80 s     -4 o 24 '  49.24 "  (CENTER)
  6 h 32 m 49.24 s     -4 o 27 '   6.45 "  (CORNER)
  6 h 33 m 32.66 s     -4 o 18 '  40.36 "  (CORNER)
  6 h 33 m  8.98 s     -4 o 30 '  58.52 "  (CORNER)
  6 h 33 m 52.44 s     -4 o 22 '  32.36 "  (CORNER)

This error box can be refined considerably.
