This storm, caused by a sunspot called AR 3141, is at the origin of an ejection of solar energy that, therefore, had consequences this Monday, November 7, on our good old Earth.

An average solar storm but with very real consequences.

As our colleagues at The Independent report, this storm caused a major radio outage in the South Pacific, affecting parts of Australia in particular, but also all of New Zealand. Perhaps the premises of another next “impact” on Earth in the next few hours, since “NOAA meteorologists (Editor’s Note: Space Weather Prediction Center) have increased the risk of class M solar flares today by 25% “, spaceweather.com details.

Some storms could have catastrophic consequences

For the record, classes A, B, and C of these solar storms relate to low-intensity events, while class X flares are the most intense flares. Solar storms occur regularly but rarely have consequences on Earth.

The most famous of these took place in 1859, known as the Carrington event (named after the English astronomer Richard Carrington, who studied it at the time). That summer, according to the archives of the time, there had been a great many polar lights visible even in certain tropical regions and had seriously disturbed communications by electric telegraph.

Since then, scientists have detected 10 to 100 more powerful solar storms, but luckily they didn’t hit Earth. Otherwise, they would have had catastrophic consequences.
