Five weeks after the explosion of Supernova 1987A in the LMC, speckle interferometric observations gave evidence for a second object having a velocity of a fraction of the velocity of light and a brightness of about a tenth of the luminosity of the supernova at that time. The possibility is discussed that this second object may reflect the interaction of the early UV burst of the supernova with a nearby dense and cool protostellar cloud. If this interpretation is correct, the cloud should show up as a very bright X-ray source about one year after the explosion.
