Last night, the skies across the country were transformed into a breathtaking display of pink, green, and blue as the aurora australis made a rare appearance. This stunning phenomenon, also known as the southern lights, was caused by a severe geomagnetic storm that hasn't been seen in Australia since 2003.
The mesmerizing light show was a result of the sun emitting plasma and solar flares, which then triggered four "coronal mass ejections" that sent magnetic particles hurtling towards Earth. Social media was abuzz with images of the aurora, as excited residents in Tasmania, Victoria, and South Australia shared their stunning captures. The lights were visible from 8pm to 2am, providing a magical experience for all those lucky enough to witness it.
Unfortunately, the display was not visible for those in New South Wales due to cloudy and rainy weather. However, there is still hope for those who missed out as the aurora may make another appearance tonight in Victoria and South Australia. It's a chance for those who couldn't see it last night to witness this rare and beautiful event.
The Australian Space Weather Forecasting Centre issued a warning for the G4 storm - the second-highest classification - which could potentially impact infrastructure and power signals from Saturday night to Sunday morning. The Bureau of Meteorology emphasized the importance of this warning, as it enables government and critical infrastructure operators to take necessary precautions to minimize any potential impacts on infrastructure assets and essential services.
The G4 storm has the potential to disrupt critical infrastructure, including power grids and satellite services. This could lead to disruptions in communication and satellite operations that rely on high-frequency radio communication. In the event that conditions reach G4 levels, bright auroras may even be visible in areas with lower latitudes, such as the dark areas near Sydney and Perth.
The aurora australis is a rare and magical event, and last night's display was one to remember. Let's hope for another opportunity to witness its beauty tonight in Victoria and South Australia.
