The autumnal equinox is when the sun crosses the equator. It'll still
be heading south until late December, then it will start heading
north, cross the equator again in late March and peak on it's
northerly track in late June when it starts heading south again.

So the way it looks, it'll be about September 21st or 22nd
where the sun will start making it's northerly track again. That
represents the autumnal equinox. On this day the day will be
equal in length to the night.

Thanks Jackie.
