Geomagnetic Storm 2022 April: A geomagnetic storm is expected to hit Earth today, April 7, 2022, according to the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center (SWPC) forecast.

NOAA Space Weather tweeted that a G1 (Minor) Geomagnetic Storm is headed toward Earth on April 6-7. It was caused by a filament explosion from the Sun on March 3 that centered near S22W30.

NOAA has classified the geomagnetic storm as a G1, meaning it is a minor storm of lowest damage. Geomagnetic storms are classified on a scale of G1-G5, with the latter being the most dangerous.

Geomagnetic Storms: Know Important Facts

What is a geomagnetic storm?

A geomagnetic storm is a major disturbance in Earth’s magnetosphere caused by the exchange of energy from the solar wind to the space weather around Earth. This is caused by the solar wind shock wave that interacts with the Earth’s magnetic field.

Geomagnetic Storm 2022 Cause

The minor geomagnetic storm was followed on March 3 by a coronal mass ejection (a significant release of plasma and magnetic field from the Sun’s corona into the solar wind) from a 25-degree long filament raised from the Sun.

Effects of Geomagnetic Storms on Earth

Geomagnetic storms can cause major changes in currents, plasma and fields in Earth’s magnetosphere.

A geomagnetic storm can cause power grid fluctuations, push auroras to higher altitudes and have minor effects on satellites in low Earth orbit.

A strong geomagnetic storm of categories G4 and G5 can affect power grids, power plants, Internet, radio and satellite communications and navigation systems. It can affect power and communication on Earth.

Geomagnetic Storm 2022

A geomagnetic storm, classified as G2 or moderate, previously hit Earth on February 3, 2022, causing massive damage to SpaceX founder Elon Musk’s Starlink project. The flames from the geomagnetic storm reportedly damaged 40 of the Starlink project’s 49 satellites.


A second filament explosion occurred on March 4, 2022, but the event is not expected to have any impact on Earth.
