Australian residents are bracing themselves for the possibility of witnessing breathtaking auroras as a severe solar storm intensifies, potentially illuminating the night sky. The National Emergency Management Agency has been monitoring the "severe" geomagnetic storm, which could lead to spectacular displays of the southern lights.
According to astrophysicist and science communicator Sara Webb, solar storms occur when particles and plasma are ejected from the sun's surface into space, interacting with Earth's magnetic field. When these particles collide with our atmosphere, they create the mesmerizing auroras.
While the storm is most likely to be visible in areas as far north as Victoria and New South Wales, viewers in New Zealand and Tasmania have a better chance of witnessing vivid displays. However, even for those who are farther away from the South Pole, the last few years have been surprisingly favorable for aurora sightings.
Solar expert Hannah Schunker cautions that while the display could appear at any moment and typically lasts between 20 to 60 minutes, it may also cause disruptions to power grids and other technology. The storm's intense energy could alter Earth's magnetic field, generating strong electric currents that can damage power grids and affect satellite communications.
The National Oceanic and Atmospheric Administration (NOAA) has warned that this is the most intense geomagnetic storm in over two decades, which may lead to auroras visible beyond their normal range. However, the agency also notes that the storm poses risks to satellite operations and GPS communications.
Meanwhile, power companies are closely monitoring their grids, while satellite operators will be watching for anomalies on GPS data. As the solar storm intensifies, it remains unclear whether there will be significant impacts on power grids or global infrastructure.
