Abstract

The central star of the planetary nebula NGC 246 is a resolved visual binary. We present CCD photometry of the G8 - K0 V companion, which is located 3″.8 from the hot nucleus. By fitting the companion to the zero-age main sequence, we derive a distance of d = 495+145-100 pc. This is one of the more secure distances known for a Galactic planetary nebula, but it could be improved still further with a better estimate of the metallicity of the system.
