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.

A geomagnetic storm is a major disturbance of Earth's magnetosphere that occurs when there is a very efficient exchange of energy from the solar wind into the space environment surrounding Earth. These storms result from variations in the solar wind that produces major changes in the currents, plasmas, and fields in Earth’s magnetosphere.

G1- Minor geomagnetic storm conditions were observed on 09 Feb 2025. Monitor our website for the latest forecasts, warnings, and alerts. Beginning February 6, 2025, the Space Weather Prediction Center is presenting new coronagraph images from the GOES-19 Compact Coronagraph-1 (CCOR-1).

Oct 12, 2024 · The anticipated coronal mass ejection (CME) arrived at Earth at 11:15am EDT at nearly 1.5 million miles per hour. The CME strength and structure are being closely scrutinized for potential geomagnetic storm intensity, but, G3 levels are now expected due to the magnitude and potential of the CME, therefore G3 or greater warning has been issued.

Oct 10, 2024 · An enormous mass of charged particles that erupted from the sun on Tuesday (Oct. 8) has slammed into Earth, triggering a "severe" G4-class geomagnetic storm.

Jul 21, 2024 · A geomagnetic storm is an enormous disturbance in Earth’s magnetosphere caused by an efficient energy exchange from the solar wind into the space environment surrounding Earth. Geomagnetic storms happen because of distinct changes in the solar wind's speed, density, and magnetic properties.

Oct 10, 2024 · A severe magnetic storm commenced at 11:15 Eastern Daylight Time on October 10, 2024. The storm is ongoing. According to the NOAA Space Weather Prediction Center geomagnetic disturbance index, which classifies storms on a scale from G1 (minor)-G5 (extreme), the storm has, as of now, attained a G4 (severe) level of disturbance.

Feb 11, 2025 · Geomagnetic storm, disturbance of Earth’s upper atmosphere brought on by coronal mass ejections—i.e., large eruptions from the Sun’s outer atmosphere, or corona. The material associated with these eruptions consists primarily of protons and electrons with an energy of a few thousand electron volts.

May 10, 2024 · Geomagnetic storms can impact infrastructure in near-Earth orbit and on Earth’s surface, potentially disrupting communications, the electric power grid, navigation, radio and satellite operations. SWPC has notified the operators …

Oct 8, 2024 · A geomagnetic storm is a disturbance in Earth's magnetic field caused by solar activity. There's a reaction called nuclear fusion that occurs continuously deep within the sun's core. This ...
