Welcome, Autumnal Equinox

Via StarDate.org.

One of the great rhythms of the sky is the up-and-down "nodding" of the Sun. Over the course of a year, the Sun moves north and south on the sky. That means it rises and sets at different points on the horizon, and it moves higher or lower at noontime.

This weekend, the Sun's right in the middle of that annual migration -- a point known as the equinox. It rises due east and sets due west, so if you want to find east and west from your house, this is the time of year to do it. And the Sun stands at its highest point in the sky at exactly local noon -- something that isn't always the case on other days of the year.
