Abstract

First detected at 6 cm in 1980 November, only 1 month after optical maximum, and several months later at 20 cm in 1981 March, SN 1980K has now dropped below reasonable monitoring limits of the VLA at these two frequencies. It thus represents the first Type II radio supernova to have been well-studied at centimeter wavelengths from «turn-on» to «turn-off.» It also represents one of the few radio supernovae to have such an extensive, decade-long, multiple-frequency data set. New observations of SN 1980K made with the VLA at 20 and 6 cm from 1984 November through 1990 December ar presented
