The sun has been unusually active over the past few days , with a total of 17 major explosions around sunspot AR2975 on Monday , said. Accordingly, the eruptions led to a total of 3 different coronal mass ejections (CME).

From this, a so-called solar storm is brewing, which is expected to hit the earth’s electromagnetic field on Thursday, March 31st . The geomagnetic storm is classified as G2 by the US National Oceanic and Atmospheric Administration (NOAA).

Moderate storm expected

The NOAA scale classifies such storms from 1 to 5. Stage 2 is a “moderate” storm . There is no risk to power grids or satellites in this category. Instead, extensive northern lights are possible up to 55 degrees latitude (among other things Glasgow).

Spaceweather writes that the solar flares could also result in a G3 category geomagnetic storm . According to NOAA, this is unlikely. Such a solar storm could disrupt wireless communication links as well as power grids on Earth.

The biggest solar storms

Strongest researched storm: Around 9,200 years ago, the  strongest storm to date is said to have  hit the earth. Researchers recently discovered evidence of the storm in the Antarctic ice.

Carrington Event: Occurred in 1859. Considered the most violent storm on record. According to reports, even auroras could be seen at the equator. Among others, the then well-known solar researcher Richard Christopher Carrington observed him.

Quebec Storm: Hit the ground in 1989. 6 million people in the Canadian province of Québec sat in the dark for 9 hours. The reason was a widespread power failure.

Halloween Storm: In October 2003, caused power outages in Sweden and a short-term collapse of the European flight radar. The 390 million euro satellite “Midori 2” was lost.
