Because the moon's orbit is tilted about five degrees from the ecliptic it can get further north than the sun.
This can be an advantage for more northerly observers, however there is a downside.
At other times the moon will be five degrees south of the ecliptic and not as far north as the sun at its highest.
This occurs on a cycle of roughly 19 years.
Although it is academic for lower latitude observers it means that northern Europe will have opportunities for lunar circumhorizon arcs in some years but not others.
