Hmmm, and here I thought all along that it was a result of the imperfect sphere that our Earth is...

Why the Equinox isn't equal by Brett Shepard is an excellent and consist explanation of an interesting geographical and astronomical phenomena. The refraction discussion was a great thing to point out. We are often taught that on the shortest day of the year the sun is not visible above the Arctic or Antarctic Circle, but that is not the case within about 30 miles north of the Circle. In Kotzebue (which is above the Arctic Circle) you will see the sun on the shortest day of the year because of refraction! Keep up the good work Brett!

this refraction can be meant to any ray of light in the universe... a planet, solar system, comets, the sun, even lights from a flash light! it just has to travel for a distance to be able to bend!

If we're being picky...
1. the time when the sun crosses the plane of the earth's equator, making night and day of APPROXIMATELY equal length all over the earth
2. Either of two points on the celestial sphere at which the ecliptic intersects the celestial equator.
