What happens during equinox?

The equinox marks the transition from summer to autumn in the southern hemisphere, and will have almost the same number of hours of daylight as darkness!

The equinox marks several astronomical phenomena too! During the equinox, the Sun will rise directly in the east and set due west. The Sun will also appear exactly halfway between its northern most and southern most location in the sky. The exact time of the equinox occurs when the sun is directly above the Earth’s equator, for 2023 this will occur at 5:24am for West Australians.
