A solar storm hit the earth, causing a radio blackout in several countries

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

An average solar storm but with very real consequences. Classified M5, the letter M designating the class of solar flares of medium intensity, the phenomenon that has occurred in recent days and whose “impact” on Earth took place this Monday, November 7 in the morning, according to the site specializing in the activity solar spaceweather.com, caused some damage in the southern hemisphere.

An R2 (Moderate) radio blackout was observed at 00:11 UTC on 07 Nov (19:11 Eastern) resulting from an M5 flare from Sunspot Region 3141.

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

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 eruptions are the most intense eruptions. Solar storms occur regularly but rare are those that 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, very many polar auroras visible even in certain tropical regions had occurred and had seriously disturbed telecommunications by electric telegraph.

Since then, scientists have spotted 10 to 100 solar storms more powerful, but fortunately did not hit Earth. Otherwise, they would have had catastrophic consequences.
