摘要：

We present the V and I light curves of a nova discovered in the disk of the spiral galaxy M100, located in the Virgo Cluster. In spite of the fact that the light curve is not well sampled around maximum light and the reddening to the nova is not accurately known, by adopting the maximum magnitude versus rate of decline relation by Della Valle & Livio we derive a distance modulus to M100 of mu(0) similar to 31.0 +/- 0.3 mag, fully consistent with the Cepheid distance modulus of 31.04 +/- 0.17 mag found by Ferrarese et al. from the same set of HST/WFPC2 data.
