THE 8–13-μm flux from supernova 1987A has increased substantially1 since around May 1988 (∼ 450 days after the explosion), and the 8–13-μm source has been resolvable1, having a full width at half maximum of ∼1.5" in September 1988. This is attributed1 to re-radiation by an asymmetric circumstellar dust cloud, located mainly behind the supernova at a distance of ∼200 light days. This cloud may be related to the gas shell inferred from ultraviolet lines2,3. Here we extend the calculations of… Expand
