A new automated technique for detecting supernovae on pairs of IIIaJ Schmidt plates is described and the initial results presented. Analysis of 2144 galaxies on 4 plates produced 3 supernovae indicating a supernova rate per galaxy of one every 160 + or - 50 years. Selection effects are discussed briefly and will be dealt with in more detail elsewhere. The technique will be used to determine an objective estimate for the supernova rate and to detect faint supernovae in real-time in order to measure the Hubble constant. A turn-around time of under 12 hours is possible after receipt of plates.
