  We derive the energy asymmetry given the proto-neutronstar during the time
when the neutrino sphere is near the surface of the proto-neutron star, using
the modified URCA process. The electrons produced with the anti-neutrinos are
in Landau levels due to the strong magnetic field, and this leads to asymmetry
in the neutrino momentum, and a pulsar kick. Our main prediction is that the
large pulsar kicks start at about 10 s and last for about 10 s, with the
corresponding neutrinos correlated in the direction of the magnetic field.
