The spatial distribution of 11-micron radiation from Omicron Ceti has been observed at various phases of its light cycle by using a stellar interferometer. Variations have been seen in the strength of thermal emission from circumstellar dust relative to the stellar continuum at 11 microns. These variations are shown to be correlated with the changes in luminosity of Omicron Ceti in such a way that dust-grain emission at 11 microns was increased more than the continuum during the period of maximum luminosity. The degree of the change in dust-grain emission implies that the maximum dust temperature is in the range of 500 to 700 K during minimum stellar luminosity.
