“…Weak wiggling patterns can be found, in particular at epoch 2001.20, 2001.48, 2002.14, and 2002.45. These parsec-scale characteristics agree with results in the VLBI images previously obtained at 1.6 GHz and 5.0 GHz (Fraix-Burnet et al 1997;Xu et al 2000;Giovannini et al 2001).…”

We present proper motion of the sub-parsec scale jet in a nearby elliptical galaxy 3C 66B. Observations were made using the VLBA and partly Effelsburg 100-m telescope at 2.3 GHz and 8.4 GHz at 10 epochs over 4 years. The 8.4 GHz images showed that a proper motion increases from 0.21 to 0.70 mas year −1 , corresponding to an apparent speed of 0.30 c to 0.96 c, with a distance from the core on a sub-parsec scale. Our investigation suggests that the apparent increase of the proper motion can be explained by changes in the viewing angle, according to a relativistic beaming model. However, we still cannot eliminate the possibility that acceleration of the jet outflow speed or of changes of emissivity profile in the two-zone jet might be found in 3C 66B.

“…High-resolution imaging using very long baseline interferometry (VLBI) has revealed an asymmetric core-jet structure similar to that observed in radio galaxies (Fraix-Burnet et al 1997;Xu et al 2000;Giovannini et al 2001). Obser-vation at 5.0 GHz reveals the presence of a faint counterjet (Giovannini et al 2001).…”
