  Over a total of 20 gamma-ray bursts localized with arcmin accuracies,
GRB980519 represents the 13th detected by the BeppoSAX Wide Field Cameras. An
X-ray TOO observation performed by the BeppoSAX Narrow Field Instruments,
starting about 9.5 hours after the high energy event, revealed X-ray afterglow
emission in the 0.1--10 keV energy range. The flux decay was particularly fast
with a power-law index of ~ 1.8. This is the fastest decay so far measured.
Signs of bursting activity are evident. The power-law spectral index of 2.8
(+0.6, -0.5) is quite soft but not unique among GRB afterglows.
