Scientific paper

We present Very Large Array (VLA) continuum observations of the core of KjPn 8 made with arc second angular resolution and taken at three epochs over a period of 2.8 years. The radio appearance of the planetary nebula seems to have experienced changes, tentatively attributed to variable illumination coming from the nucleus. We also present VLA observations of atomic hydrogen toward this source, made with an angular resolution of about 40''. We detect associated emission that suggests the presence of a mass of atomic hydrogen of order 0.07 M[ scriptstyle sun ]in the envelope.
