Letter to the Editor
Low luminosity type II + Ib,c supernovae *
Received 15 August 1997 / Accepted 16 September 1997
A combined sample has been constructed of supernovae of types II or Ib,c in our Galaxy and in external galaxies nearer than 4 Mpc. It is concluded that the luminosity function remains relatively flat down to = -13 to -14. Supernova rates obtained from traditional extraglactic samples should probably be increased by a factor of 1.5 - 2. A relatively simple observational programme could yield more definite answers in five to ten years time.
