Abstract
We present optical photometry for the type Ic SN 1994I in M51 (NGC 5194) from 1994 March 31 to August 6, UT starting eight days before B-band maximum and ending three months later. We estimate the extinction to SN 1994I was considerable and quite uncertain, A_v_= 1.4+/-0.5 mag, making a detailed comparison to other supernovae difficult. Using a distance modulus μ = 29.6+/-0.3 mag to M51, we calculate absolute magnitudes and a quasibolometric light curve for the supernova. It appears that SN 1994I was less luminous than "normal" type Ia SNe. There is strong evidence that the ejecta of SN 1994I were much less massive than those of other SNe.
