Scientific paper

High-resolution images of the M supergiant Betelgeuse in February 1989 at wavelengths of 633, 700, and 710 nm were made using the nonredundant masking method. At all these wavelengths, there is unambiguous evidence for an asymmetric feature on the surface of the star, which contributes 10-15 percent of the total observed flux. This might be due to a close companion passing in front of the stellar disk or, more likely, to large-scale convection in the stellar atmosphere.
