Scientific paper

The discovery and light curve of a very distant supernova (redshift approximately 0.5) are reported. The object was detected on 1.2-m Schmidt plates taken a total of 10 months apart using a blink comparator, and supernova magnitudes were determined by an integration method. Plots of magnitude against epoch indicate a best fit decay time of 5.8 + or - 0.5 days/magnitude for the supernova which reached a peak B magnitude of 21.4. In addition, comparison of the observed decay time with that expected for a supernova at the estimated red shift of the underlying galaxy suggests that light from the supernova has not undergone a Doppler shift.
