GCN Circular 509

K. Hurley, on behalf of the Ulysses GRB team, M. Feroci, on behalf
of the BeppoSAX GRB team, and T. Cline, on behalf of the NEAR GRB
team, report:

Ulysses, the BeppoSAX GRBM, and NEAR observed a ~25 s long burst
whose 25-100 keV fluence was ~2 x 10^-6 erg/cm^2 on December 26, 
1999 at 14:59:57 UT.  We have triangulated this burst to two
possible ~70 sq. arcmin. error boxes, whose coordinates are given
below.  Further examination of the BeppoSAX data should allow us
to determine which of the intersections the burst originates
from.
