The Autumn Equinox

The 2019 autumn equinox in the Northern Hemisphere occurs Monday, September 23, at 0:51am PDT (07:51 UT), when the Sun enters Libra. It is one of the two days of the year that the Sun moves across the celestial equator, the imaginary line among the stars that lies directly above the Earth's equator circling from east to west. The Sun's crossing of the celestial equator occurs one other time on the spring equinox. Both times this crossing occurs, the Sun rises exactly due east and sets exactly due west!


The Sun crosses the celestial equator at both equinoxes.
The Sun is ascending "springing" in March,
and descending "falling" in September.

At this special moment – the instant of the September equinox – the midday sun will be at zenith, or straight overhead, at the Earth’s equator. That’s the meaning of equinox. The September equinox sun crosses the sky’s equator, going from north to south.

Who will see the sun overhead at the moment of this year’s equinox? ... Everyone along Earth’s equator on the day of the equinox – and for a day or two before and after it – will experience that noonday sun more or less overhead.

... On the day of the equinox, the sun rises due east and sets due west all over the world, with everyone worldwide receiving approximately equal portions of day and night.

Note: The Sun crosses the equator from north to south for both hemispheres at the September equinox, however the Sun's path "springs up" toward the north for the Southern Hemisphere's springtime and continues to "fall" toward the south for the Northern Hemisphere's fall or autumn. (Reminder: Spring begins in the SH and autumn begins in the NH at the Sept. equinox.)

Equinox, which means "equal night" refers to a time when the length of day and night are equal. As the Sun crosses the celestial equator, the axis of the Earth points neither toward nor away from the Sun resulting in 12 hours of darkness and light over the planet.

... Since the Earth's tilt relative to the Sun is constantly changing, the 12-hour symmetry can be only approximately true anywhere. However, if you look at the sunrise sunset times for your location, you find that it is several minutes off on this date. Why? It's because the refracting or bending effects of the Earth's atmosphere alters the observed time of sunrise and sunset. The Sun rises a little earlier and sets a little later due to this effect, causing the observed equinox to precede the true equinox by a few days in spring. In the fall it follows by a few days.

Seasons and the Celestial Sphere

The path of the Sun in the sky intersects the celestial sphere and marks the seasons. At the spring and autumn equinoxes, when the Sun intersects the celestial equator it rises due east and sets due west. At the summer solstice, when the Sun reaches its highest point north of the celestial equator it rises as far northeast as it can and sets as far northwest as it can. At the winter solstice, when the Sun reaches its lowest point south of the celestial equator it rises as far southeast as it can and sets as far southwest as it can.

... on the week before and after the equinox the Sun changes its rising and setting position on the horizon each day by a full Sun's width, which is over half a degree. (moving from north to south) Of course you have to be careful not to stare at the Sun as it rises or sets. On the equinox it will rise due east and set due west, but then the following week watch it again dramatically change ... as it moves from due east toward the south and you'll be absolutely amazed!

Celestial Sphere ~ Key Concepts

The autumn equinox occurs at the exact moment in time
when the Sun, heading from the north to the south,
appears in the sky at the point
where the ecliptic crosses the celestial equator.


Here's a list of autumn equinox facts from The Seasons by the Astronomy Club of Tulsa:

The direct rays (of the Sun) are at the equator

Six months of darkness begins at the North Pole

Six months of light begins at the South Pole

Twelve hours of darkness and twelve hours of light all over the earth

It is the longest day of the year on the equator, again (spring equinox is the longest day, previous)

The sun rises due east and sets due west

Autumn begins in the Northern Hemisphere

Spring begins in the Southern Hemisphere
