Abstract

In recent years, light echoes have been discovered around some nearby extragalactic supernovae (SNe) well after the explosion. However, to date no light echoes of historical SNe of Galactic or extragalactic origin have been discovered. The SuperMACHO project has discovered echoes from three ancient SNe in the Large Magellaninc Cloud. Spectra of the light echoes taken with GMOS on Gemini South indicate that one of them is an overluminous SN Ia.
