Space weather refers to the conditions on the Sun and in the solar wind that affect Earth’s magnetic field and atmosphere. The live forecast above shows current geomagnetic activity and solar radiation levels, helping you track potential impacts across Australia as we approach the peak of Solar Cycle 25.
What drives space weather?
Solar flares and coronal mass ejections (CMEs) from the Sun send charged particles hurtling towards Earth. When these particles interact with our magnetic field, they can trigger geomagnetic storms, disrupt radio communications, and create stunning auroras. The Bureau of Meteorology and NOAA space weather centres monitor these events in real time.
How does space weather affect Australia?
Australians can see the aurora australis during strong geomagnetic storms, particularly from Tasmania and southern Victoria. Space weather also disrupts GPS accuracy, high-frequency radio, and satellite operations – something farmers, pilots and emergency services rely on. The Australia weather hub links to local conditions influenced by solar activity.
Can I see the aurora tonight?
Check the live forecast above for the Kp-index. If it’s 5 or higher, cloud-free skies in southern Tasmania, Victoria or southern NSW offer the best chance. Use a space weather app for real-time alerts.
Is space weather dangerous for everyday Australians?
Most space weather events are harmless on the ground. Extreme storms can temporarily disrupt power grids and GPS, but Australia’s infrastructure is well-protected. The Bureau of Meteorology issues advisories when needed.
How is space weather forecast?
Forecasters combine satellite images of the Sun, real-time solar wind data, and computer models. The live forecast above is updated frequently, drawing on NOAA space weather and Australian data. Check the Bureau of Meteorology’s space weather page for detailed outlooks.
