Scientific paper

Selection effects in the historical sightings of supernovae are used to estimate the frequency of such events within our Galaxy. A result of one supernova every 30 years or less is implied. A reconciliation of the data from supernova remnants and estimated time intervals between extra-galactic supernovae, galactic supernovae and pulsar formation only appears possible if fewer than one in five galactic supernovae leave long-lived radio remnants, although a much larger fraction must produce pulsars.
