A _real double sunset_ would be a rare occasion, because even
if planets around double stars are common (something that I
read more than 30 years ago), aligning the two suns with the
horizon would be uncommon for planets with orbits in the
plane of the two suns orbits and a not-too-inclined rotation
axis.
