Using data obtained when observing Cep A East, radio maps have been made of Cep A West at wavelengths of 20 and 6 cm. These data have been supplemented by further observations with the VLA with phase center at the West component. Cep A West consists of two compact sources, components 1 and 2, of which the first appears to be comparatively constant with time and the second variable in amplitude and size; in addition, there is a diffuse Component 3, which is somewhat elongated. A line joining the three components is directed towards a group of HH objects, but this is the only suggestion that there may be some interaction between them. The optical object with which the region has been associated, the HW object, has been shown to be nonstellar (Hartigan and Lada), and is probably associated with the diffuse component. The identity of the other components is uncertain, but intriguing.
