Powerful Solar Storm hit Earth causing Celestial Light Displays in Skies from Australia to Britain

An unusually powerful solar storm hit Earth on the night of May 10, causing celestial light displays from Australia to Britain. The solar storm poses a threat of potential disruptions to Earth’s communications networks, satellites, and power grids as it continues into the weekend.

  1. The solar storm was caused by coronal mass ejections (CMEs), expulsions of plasma and magnetic fields from the Sun.
  2. It was upgraded to an ‘extreme’ geomagnetic storm, the first since the ‘Halloween Storms’ of October 2003.
  3. More Coronal Mass Ejections are expected to impact the planet in the upcoming days.
  4. Social media was filled with images of auroras from northern Europe to Australia, New Zealand, and neighboring islands in the Pacific Ocean.
  5. The solar flares originated from a large cluster of sunspots, 17 times wider than Earth.
  6. The Sun is nearing the peak of an 11-year cycle, resulting in increased solar activity.
  7. Fluctuating magnetic fields during geomagnetic storms can create currents in long wires, potentially causing power outages and issues in engineering.
  8. Spacecraft are vulnerable to high levels of radiation during solar storms, but Earth’s atmosphere shields the planet.
  9. Pigeons and other species with internal biological compasses may be impacted by geomagnetic storms.
  10. The Carrington Event, the most powerful geomagnetic storm in recorded history, occurred in September 1859.
