Australia is bracing for the spectacular display of the aurora australis, also known as the southern lights, as a 'severe' solar storm hurtles towards Earth. The National Emergency Management Agency has issued an alert for January 20th warning of potential disruptions to the power grid and satellite operations.
The sun's energy is about to unleash a flurry of charged particles that will interact with our magnetic field, creating breathtaking displays of light in the night sky. According to astrophysicist Sara Webb, "solar storms are sudden events on the surface of the sun where particles and plasma are ejected away from the surface and into space."
The Bureau of Meteorology has issued a warning for 20th January, stating that severe geomagnetic storms could make auroras observable during nighttime hours in Australia, as far north as middle latitudes. However, scientists warn that not everyone will be able to witness this spectacle, with viewers in New Zealand and Tasmania having the best chance of spotting it.
The display could last anywhere from 20 minutes to an hour, but its timing is uncertain. Shawn Dahl at the National Oceanic and Atmospheric Administration (Noaa) stated that the intensity of this storm has not been seen in over two decades, which may lead to auroras being visible in places they are normally unseen.
But with this intense solar storm comes significant risks for satellite operations, GPS communications, and other infrastructure. According to US Geological Survey, it could generate strong electric currents damaging power grids and causing outages or shutdowns of critical systems.
While there is no immediate concern about the impact on the Australian power grid, experts advise that contingency plans are in place to mitigate any effects. The National Emergency Management Agency has assured that no significant impacts are expected for Aotearoa New Zealand, where the storm is likely to be most intense.
