Abstract
0646+600, an 'optically quiet quasar' has been imaged with global VLBI at 5 GHz in 1989 and 1992 and at 8.4 GHz in 1991. Between 1989 and 19 92, the overall separation of the two bright components decreased by 0 .25 mas, and a weak middle component or extension seen in 1989 was not detected in the later observations.
