Have a good look at polar sunrise

Some day it may be possible for students to enjoy this spectacle as it comes solely from the orbital motion of the Earth and the single surface rotation much like the day/night cycle we experience every 24 hours.

It attracts people who have an eye for substance and beauty and will be there each an every year for those who can pick up on the dual surface rotations of the planet.
