Abstract: | 0646+600, an optically quiet quasar has been imaged with global VLBI at 5GHz in 1989 and 1992 and at 8.4 GHz in 1991. Between 1989 and 1992, 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. |
