Abstract: We present BVRI photometry and medium resolution spectroscopy of the supernova SN2007rw during ∼ 1 week to ∼ 7 months after discovery. This supernova was classified as a type IIb event, however, based on our analysis we suggest that SN 2007rw is a type IIL supernova. With an absolute B magnitude of MB= -18.5 magnitude at peak, it is a bright IIL event. The early spectrum of SN 2007rw shows Hα and Hβ with weak P-Cygni absorption. The mass of 56Ni synthesized in the explosion is estimated as ∼ 0.43 M. The metallicity of the host galaxy in the supernova region is found to be marginally subsolar.
