Scientific paper

The authors have made a VLA observation at 6 cm of K 648, the planetary nebula in the globular cluster M15. The angular resolution is 0arcsec.4 and the rms noise is 0.1 mJy. K 648 has an angular diameter of 1arcsec.0±0arcsec.3 and a flux density of 3.1±0.6 mJy. With the known distance to M15 the physical size, total ionized nebular mass and electron density are derived. These quantities are comparable to "typical" planetary nebulae in the solar neighbourhood.
