| Movie of 3C120 from 1.7 GHz VLBA monitoring observations. This is
based on data from 1994.44, 1997.70, 2000.68, and 2002.76. The
clearly visible portion of the jet extends about 250 milliarcsecond
(mas) from the core. There is low level emission visible in the
original images but difficult to see here that extends about twice as
far. The scale is about 0.65 pc per mas and the resolution is 4 by 12.5 mas.
The faster features are moving at an apparent speed of about 6 times the
speed of light which indicates that they are moving near the speed of light
nearly along the line-of-sight.
