Results of a systematic search for outburst events in 1.4 million galaxies. In Fig. 18, we plot the number of discovered SN candidates and the number of [spectroscopically] confirmed SN over the past 22 yr. Encouragingly, this figure shows that the amount of SN follow-up has increased at an approximately linear rate over this time. However, in contrast, the SN candidate discovery rate appears well modelled by an exponential increase in addition to the linear confirmation-rate trend.
