Very light photinos, if they exist, should be produced in a SN explosion. Using the data from SN 1987A we set limits on the masses of selectrons (and squarks), the SUSY particles involved in the production (and diffusion) of photinos in the stellar medium. The bounds obtained are m e ̃>75 GeV (250 GeV) form q ̃>45 GeV (80 GeV), where m e ̃≡m e ̃L=m e ̃R. © 1989.
