Abstract
The WFPC2 observations made by J. Westphal, in July 1995, allow us to confirm the existence of condensations O', O1 and O2; they are located at intersections between the radio jet and filaments emitting in the continuum and in the lines. The depolarization of the radio jet at the position of knot R1 is related to the interaction of the jet with a strongly ionized region of the galaxy. We also detect additional knots closer than 2.5” from the nucleus. The high angular resolution brings precise measurements in position and flux. The optical and radio positions are in good agreement and the radio/optical spectral indices of the knots are as expected in the case of synchrotron radiation.
