Magnetopause

The magnetopause is the boundary between a planet's magnetosphere and the plasma solar wind emitted by the sun. It behaves roughly like a droplet of liquid exposed to supersonic flow. It is common for the magnetopause to ripple, flap and even to have large droplets break off in the wake of a planet. See also heliopause and magnetosphere.

This article defines a magnetopause as something between a planet's magnetosphere and the solar wind, and then heliopause says that the heliopause is a magnetopause between the sun's solar wind and the galaxy's plasma currents. While I can see what the articles are getting at, they are prima facie contradictory, and should be reworded (probably by using a more general definition of magnetopause).
