Abstract

We present subarcsecond resolution VLA observations at wavelengths of 6 and 1.3 cm of the core-dominated quasar 1510-089. We find a counter component opposite to the main jet at a distance of -093 from the core. It is not clear yet whether this counter component is a knot near the base of a counter jet or a hotspot at the end of a counter jet. If the latter, and the two jets are ejected symmetrically from the nucleus, then the estimated hotspot advance speed is βhs cosθ≃0.93 assuming that the difference in angular extents of the two sides of the source is due to the relative light travel times. This value seems high but is not currently ruled out.
