Facts about the autumnal equinox: 

• This year's autumnal equinox is on Monday, September 23, 2019 at 1:50 am MDT in Colorado, marking the first day of fall in the Northern Hemisphere.

• The sun crosses the Earth's equator at the time of the equinox, from the Northern Hemisphere into the Southern Hemisphere.

• During the autumnal equinox, day and night are balanced to about 12 hours each all across the world.

• In the far north, the autumnal equinox signals peak viewing of the aurora borealis or northern lights.The celestial display of brilliantly colored lights happens when charged particles from the sun strike atoms in Earth’s atmosphere, causing them to light up. These light displays peak around the fall and spring equinox. That’s because disturbances in Earth’s atmosphere—known as geomagnetic storms—are strongest at these times.
