Abstract:
We present new VLA, MERLIN, and VLBI images for the radio galaxy 3C 338 and the results of the monitoring of its arcsecond core flux density. Present high-sensitivity observations allow us to investigate the radio structure of this source and to confirm the presence of two symmetric parsec-scale jets. Morphological changes between different epochs are evident, and a proper motion with ~ 0.4 h~l has been derived. This allows us to give a lower limit for the Hubble constant. While the steep-spectrum largescale structure of 3C 338 could be a relic emission, the small-scale structure looks young, similar to the high-power medium-sized symmetric objects (MSOs) found at high redshift. © 1998.
