dc.description.abstract	Results obtained from infrared observations of SN 1987A have been summarized. The supernova developed near-infrared excesses with a characteristic temperature ~1250 k beginning around March 15, 1987. Infrared speckle interferometry began to partially resolve the supernova from mid-June, and on August 6 a fully resolved structure (~0.42 arc second) was observed: consistent only with a light echo. Infrared spectroscopy in early October showed that all the lines and the molecular CO bands were redshifted with respect to the LMC by ~ 400-1500 km/sec. The dust responsible for the infrared light echo is expected to thermally reemit at far-infrared wavelengths (~30µm) which should be looked for.
