SN1987A formed spectacular light echoes which have been used to study the dust geometry in the Large Magellanic Cloud (LMC). Because the surface brightness of echoes often does not decrease rapidly with time, we have searched our 4 year SuperMACHO images of the LMC for other echoes of supernovae and other variable objects. Much to our surprise, we found echo arcs whose apparent vector motions clearly point back to three well defined positions in the LMC. Even more surprisingly, these three positions correspond to 3 of the 6 Supernova Remnants (SNRs) that are listed (Hughes et al 1995) both as the youngest SNRs and as possible Type Ia events in the LMC. Gemini spectroscopy obtained via DD time in March 2005 of the brightest echo arc suggests that the type Ia classification is correct. We ask for GMOS-S time to obtain higher quality spectra of all three events to classify the supernova events.
