| 英文摘要 | We report on an ongoing project aimed to detect the separation speed of the two hot-spots of the Compact Symmetric Object OQ208. Comparing images at 8.4 GHz taken in 6 epochs between 1994 and 1997 we obtain an estimate of 0.061 +/- 0.024 mas/year for the relative motion between the two outer and compact components of the radio source, and a strong upper limit of 0.13 mas/year.
