High energy neutrino bremsstrahlung nu-->nu+gamma in a strong magnetic
field (B much greater than B-s) is studied in the framework of the St
andard Model (SM). A resonance probability and a four-vector of the ne
utrino energy and momentum loss are presented. A possible manifestatio
n of the neutrino bremsstrahlung in astrophysical cataclysm of type of
a supernova explosion or a mercer of neutron stars, as an origin of c
osmological gamma-burst is briefly discussed. (C) 1997 Elsevier Scienc
