摘要：

Supernova 1993J, a Type IIpec supernova, was discovered on March 28 in the nearby galaxy M81. The spectra displayed strong Balmer lines establishing its classification as a Type II supernova. About 26 days after explosion the H alpha profile became anomalous, signaling the presence of significant amounts of helium. Additionally, the light curve displayed an anomalous double peak. We review the observations and interpretation of Supernova 1993J through the use of light curve fitting and synthetic spectra.
