A geomagnetic storm is currently affecting Earth, increasing the chances of seeing the aurora australis in Melbourne tonight, Wednesday, November 12. The Australian Space Weather Forecasting Centre has issued an alert for a severe geomagnetic storm.
As night falls, visible auroras may appear across southern and mid parts of Australia, including Melbourne. The Bureau of Meteorology notes possible sightings in dark locations near Sydney and Perth as well.
Auroras are more likely during times of high solar activity. Coronal mass ejections release dense plasma into the solar wind, which then interacts with Earth's magnetic field to create vivid displays of green, red, and purple light.
"The Australian Space Weather Forecasting Centre has issued an aurora alert, stating that a 'severe geomagnetic storm' is in process."
"Aurora sightings may even be possible in dark sky locations near Sydney or Perth."
Author's summary: A severe geomagnetic storm tonight offers a rare chance to see the Southern Lights in Melbourne and southern Australia—seek dark, clear skies and stay updated through trusted sources.
