Abstract.
Light echoes are a promising tool to probe the environment where SNe Ia explode and an independent source of information on the progenitor’s nature. After giving a brief introduction to the phenomenon I review the two known cases, i.e. SN 1991T and SN 1998bu. We then present the results obtained from the test case of SN 1998es in NGC 632. This object was classified as a 1991T-like event and was affected by a strong reddening, a fact which made it a good candidate for a light echo detection.
