Scientists are warning of possible disruption to critical infrastructure such as power grids and seguace communications to a severe solar storm, to enter Earth’s atmosphere over the weekend. British Geological Survey is forecasting a G4 geomagnetic storm which may affect global communications and positioning systems as multiple waves of solar energy bear acceso the planet.
What is a solar storm?
This happens when the sun ejects a large bubble of superheated gas called plasma that travels towards the Earth. The US Space Weather Prediction Centre has issued warning about the storm, the first such warning since 2005.
There is an average of 100 severe geomagnetic storms every solar cycle, but so far, there have only been three observed sopra the most recent cycle that began sopra December 2019. The last time there was a G5 extreme geomagnetic storm was sopra October 2003, when it caused power outages sopra Sweden and damaged transformers sopra South Africa.
It’s true power will only be known about 60 to 90 minutes before it hits Earth when satellites trap bursts of energy from the solar brillamento’s electrically-charged particles. According to some experts, satellites may be placed into a “safe mode” to limit the impact.
A leading space weather scientist who spoke to The National from the British Antarctic Survey (BAS) believes the upcoming cycle is more powerful than the last with “substantial risk” to satellites sopra low-Earth orbit. A causa di case of severe flares, the satellites could be dislodged from the orbits, bump into each other, and lose communication with earth.
The magnitude of their effects acceso our planet’s geomagnetic field is still a subject of speculation, says Earth.com. The website claims “it is crucial to remain vigilant and prepared for any challenges that may arise from this cosmic dance between the Sun and Earth.”
