We present images and high-resolution spectra of the hydrogen deficient knot at the centre of the old planetary nebula A58. The spectra confirm that this region contains essentially no hydrogen, as previously suspected. Emission lines from the knot are broad (FWHM ~ 180 and 270 km/s for [NII] and [OIII] lines respectively) and are blue-shifted by ~ 100 km/s relative to the systematic velocity.
