A huge solar storm hitting the Earth today could cause massive disruptions to power grids and satellites



A huge solar flare is expected to affect the Earth today, which could affect power grids and generate an aurora in northern latitudes.

Coronal mass expulsion comes from the Sun, which is caused by a huge explosion of electrically conducting plasma.

An alert issued by the U.S. Oceanic and Atmospheric Administration (NOAA) reported that we should expect “weak power grid fluctuations” and “orientation irregularities” from satellites that could increase ship drag. in low Earth orbit.

The agency rates the storm as G2, which means it is moderately strong. It is expected to arrive around noon and will continue until October 12th.

“Aurora is possible through [the] Eleventh in much of Scotland, although cloud numbers are rising, meaning they are unlikely to be seen, ”the Met Office said, according to Sky.

“There is a small chance that the aurora will reach the far north of England and Northern Ireland tonight, but the cloud will break and therefore be more likely to be seen in Northern Ireland.”

While this storm will be relatively weak, the planet is not ready for the height of a more powerful super storm.

On May 15, 1921, multiple fires broke out in the control rooms of electricity and telegraphs in various parts of the world, including the United States and the United Kingdom, due to the force of the New York rail storm.

Storms like these occur once every 100 years and can plunge the world into an “Internet apocalypse,” according to a study.

“Coronary mass expulsion (CME) involves the emission of electrically charged matter and the magnetic field that accompanies it into space. When it hits the earth, it interacts with the Earth’s magnetic field and produces geomagnetically induced currents (GICs) in the crust, ”said Dr. Sangeetha Abdu Jyothi of the University of California, Irvine and VMware Research.

“In today’s long-distance Internet cables, fiber optics are immune to GICs. But these cables also have power supply repeaters at intervals of ~ 100 km susceptible to damage.
