  Recently the OPERA collaboration {\cite{opera}} has reported the observation
of superluminal neutrinos traveling a distance of 730 km from Grand Sasso
Laboratory to CERN.These results contradict the basic tenet of the Theory of
Special Relativity: No particle can travel faster than light in vacuum.
Moreover they seem to be in conflict with the speed of (anti)neutrinos detected
from the explosion of the SP1987A Super Nova{\cite{SP1987A}}.Here we show that
the relative velocity between neutrino and photon has the following property:
It depends weakly on the energy of the particle excepts in certain
regions(thresholds) where discrete jumps appear.This explains both Opera and
SP1987A Super Nova data.
