Abstract

The infrared source MWC 349 was resolved by one-dimensional infrared speckle interferometry in east-west, and marginally in north-south direction. This is considered as direct evidence for a circumstellar dust distribution, possibly disk-shaped, postulated by earlier optical and radio investigations.
