Optical Observations of SN 1988G
Abstract
We present optical spectroscopy and photometry of the Type Ia supernova SN 1988G obtained shortly after discovery. We have determined the redshift of the parent galaxy as 7055 km sec^-1^. Adopting a distance of 88 Mpc, the supernova has an absolute magnitude of M_B_= -18.8. Based on the luminosity and the characteristics displayed by the optical spectrum we infer that maximum light occurred within a few days of the discovery.
