Scientific paper

The technique of speckle interferometry is applied to Chi Cygni, a Mira-type variable, giving a mean diameter of (23.08 plus or minus 4.08) x 10 to the -3rd arcsec. Two methods of data reduction were applied giving good agreement with each other. The result tends to support the conclusion of Labeyrie et al. (1977) that Mira stars have radii R not greater than 18 solar radii as opposed to the previously assumed value of R 320 solar radii.
