This weekend marks the celestial event of the equinox. It is the moment that the sun is straight overhead the equator and swings from the northern hemisphere to the southern hemisphere.
This weekend across the globe we all saw an even distribution of day and night.
For the scientists on the South Pole today?s sunrise is the start of their 6-month long ?day?.
Across Australia?s north and interior the warmth of the spring sun has already been felt, a bit earlier than normal. Today's 39.8 degrees in Mt Isa is it's hottest September day on record. Nearby, Camooweal's 40.6 degrees makes this its hottest day this early in the season on record. With the sun edging more overhead combined with many cloud free days, the build-up season has been well under way. This heat is expected to act as fuel for storms to come.
The sun has been plentiful on this equinox day across the nation?s northern and eastern capitals: Darwin, Brisbane, Sydney and Canberra all saw plenty of the sun and experienced a warm Sunday away from coastal sea breezes.
Across the country?s south a cold front brought the reminder that this is also the season of cold contrasts, bringing snow to the Tassie mountains.
