Scientific paper

The paper presents the results of speckle-interferometry of SN 1987A in the 2-5 micron spectral range, carried out in May, June and August 1987 at the 3.6 m telescope at ESO. The observations revealed the presence of a faint emission in the vicinity of the SN on June 17-22 in the L prime band and on August 5-6 in the K, L prime, and M bands. An IR light echo from dust clumps appears as the most plausible explanation of the IR speckle sources.
