February 3 – A geomagnetic storm impacted the areas around the Arctic Ocean and disrupted up to 40 new SpaceX Starlink satellites that were launched earlier in the day. [148] The storm also caused the Space Weather Prediction Center (SWPC) to issue a G1 geomagnetic storm warning. [149] February 4 – A series of avalanches killed eight people ...
A geomagnetic storm, also known as a magnetic storm, is a temporary disturbance of the Earth's magnetosphere caused by a solar wind shock wave. The disturbance that drives the magnetic storm may be a solar coronal mass ejection (CME) or (much less severely) a corotating interaction region (CIR), a high-speed stream of solar wind originating ...
This is the third geomagnetic storm to reach G4 status during the current 11-year solar cycle, which began in 2019, officials said.
An extreme (G5) geomagnetic storm alert was issued by the National Oceanic and Atmospheric Administration (NOAA) – the first in almost 20 years. [ 96 ] [ 97 ] The final storms reaching the highest level of NOAA's G-scale before Solar Cycle 25 occurred in 2005 in May, [ 98 ] [ 99 ] [ 100 ] August, [ 101 ] and September, respectively.

The largest magnetospheric-ionospheric current variations, resulting in the largest external magnetic field variations, occur during geomagnetic storms and it is then that the largest GIC occur. Significant variation periods are typically from seconds to about an hour, so the induction process involves the upper mantle and lithosphere .
The National Oceanic and Atmospheric Administration's Space Weather Prediction Center predicted a minor geomagnetic storm for Tuesday, here's what that means. Geomagnetic storm could impact ...
