Autumn equinox

Today is the autumn equinox.
Perfect symmetry between the 2 hemispheres that receive the same amount of solar energy over a day with 12 hours of day/12 hours of night.
Can you see the sun's track exactly on the equator in this satellite animation?

This year's Autumnal Equinox falls on 22 September at 14:30 BST.
The equinox is when the centre of the Sun (as viewed from Earth) crosses the Earth's equator.
