Authorities in the US: A rare solar storm is coming to Earth

A high-intensity solar storm is heading toward Earth and could cause problems tonight for power grids and satellites, US authorities have warned.

"We are almost certain that charged solar particles ejected from the Sun's corona are headed toward Earth," explained Sean Dahl of the Space Weather Prediction Center (SWPC) at a press conference.

The Center issued a Category 4 (out of 5) geomagnetic storm warning, which has not occurred since 2005.

It is difficult to predict the exact beginning of the phenomenon, but it will last throughout the weekend.

"It can affect the infrastructure", said Dahl, clarifying that this phenomenon is "very rare". "We have notified all the providers we work with, those who operate satellites, communications and, of course, the North American power grid," he added.

The Sun is currently near the peak of its activity based on its 11-year cycle. These coronal mass explosions, of which at least seven are directed toward Earth, originate from a sunspot about 16 times the diameter of Earth. They move at a speed of several hundred kilometers per second. When they reach the American satellites, it will be possible to predict more precisely the intensity of the phenomenon, that is, about 20-45 minutes before it reaches the Earth, explained Sean Dahl.

Dahl advised Americans to carry batteries or even generators, as they do for all storms.

Electricity providers have been working to better protect their grids for a decade, said Rob Steenberg, a scientist who works at SËPC. Power lines can be affected, but not houses, and today there are systems to avoid them. The GPS network can also be affected.

As for air traffic, the FAA does not expect any major problems.
