Type I supernovae as standard candles,hese templet light curves, and occasional deviations are explained as photometric errors, which can be quite severe in the case of SNe. The peak luminosity of absorption-free SNe I is also uniform with an intrinsic rms scatter of <0. 3 mag. The calibration of the peak luminosity yields MB(max) = -20

Radio observations of historical, extragalactic supernovae, along the inner edges of the spiral arms are likely to be the remnants of supernovae which were not seen optically. All four sources have monochromatic luminosities comparable to that of Cas A. A composite “radio light curve” for supernovae and young supernova remnants of known age is presented and discussed.
