Abstract
Based on data from the supernova SN 1987A it is shown that the Einstein equivalence principle is confirmed for electron neutrinos and their antiparticles to one part per million provided at least one of the events is due to e scattering. Bounds on the strengths of new galactic-range forces coupling to neutrinos (of nonzero mass) and to matter are also deduced.
