Description

During the course of high-frequency flux-density measurements on sources exhibiting low-frequency cutoffs, at least three such sources, 4C 79.4, 4C 79.15, and PKS 2344+09, revealed structure on a scale ranging from a fraction of a minute of arc to as much as 15 minutes of arc. This structure appears to change significantly on a time scale of several months. It is suggested that this variable structure arises from the existence of several centers that are highly variable in flux density, but fixed in position
