We discuss the Cherenkov process ν→νγ in the presence of a homogeneous magnetic field. The neutrinos are taken to be massless with only standard-model couplings. The magnetic field fulfills the dual purpose of inducing an effective neutrino-photon vertex and of modifying the photon dispersion relation such that the Cherenkov condition ω<|\bf k| is fulfilled. For a field strength B\rm crit=me2/e=4.41×1013 Gauss and for E=2me the Cherenkov rate is about 6×10-11s-1.
