The host galaxy is centred between the two jets; the position is marked
on our image by a small red dot, which coincides with the flat-spectrum core
prominent at higher resolution and frequency
(e.g. Vallée 1982,
Macklin 1983). The HST image
(Sparks et al. 2000) shows a dust disk
roughly perpendicular to the jets.
The jets are rather low contrast.
The lobes have a very sharply defined outer boundary, and
the jets reach nearly to the end of the source, so this is a classic
bridged twin-jet. In fact the north-west jet
points to a "warm spot" near the lobe boundary which might play the role
of a hotspot for this weak jet, as suggested by Macklin.
The DRAGN is in an unusually isolated environment for an FR I. There
is no discernable cluster around it and no detectable hot gas, either
via X-ray emission (Miller et al. 1999),
or Faraday rotation (Vallée 1982).
