Powerful Storm May Hit Earth Today, NASA Issues Alert
News Desk
Washington: A powerful solar storm triggered by a massive eruption on the Sun is expected to impact Earth, prompting scientists and space weather agencies to issue alerts and closely monitor its effects.
Following a major solar flare and a fast-moving coronal mass ejection (CME), the US National Aeronautics and Space Administration (NASA) and the Space Weather Prediction Center have warned of a strong G3-class geomagnetic storm that could reach Earth at any time.
Scientists say the Sun has experienced heightened activity in recent days, releasing repeated bursts of energy and charged particles into space.
While most recent eruptions were not directed toward Earth, a moderate solar flare that erupted on June 6 from Active Region 4461 sent a cloud of magnetized plasma directly toward the planet.
The eruption included a dense, fast-moving structure known as a filament, a massive ribbon of cooler, heavier solar material suspended in the Sun’s atmosphere by magnetic forces.
When those magnetic fields became unstable, the filament was violently expelled into space along with a large volume of charged particles.
Traveling at an estimated speed of 1,400 kilometers per second, the solar material is now approaching Earth and is expected to interact with the planet’s magnetic field, potentially triggering widespread geomagnetic disturbances.
According to experts, when charged particles from the Sun collide with Earth’s magnetic shield, they can create geomagnetic storms that produce spectacular auroras, also known as the Northern and Southern Lights.
These colorful displays occur when solar particles interact with gases in the upper atmosphere, creating waves of green, red and purple light across the night sky.
Scientists note that Earth’s magnetic field generally protects the planet from the harmful effects of solar storms. However, the intensity of the auroras depends largely on the orientation of the incoming magnetic field. If it is strongly aligned opposite to Earth’s magnetic field, energy can penetrate deeper into the magnetosphere, resulting in brighter and more widespread auroral displays.
Should the storm intensify, auroras could become visible far beyond the polar regions, potentially reaching parts of China and India, Central Europe, southern Australia, New Zealand, and portions of the United States.
Researchers say the storm’s ultimate strength will only become clear once the solar material reaches monitoring satellites positioned near Earth. These spacecraft can provide more accurate forecasts between 15 and 60 minutes before the storm arrives.
A similar geomagnetic storm in May 2024 produced dazzling auroral displays visible across much of the world. Astronomers, skywatchers and photographers are now eagerly awaiting the arrival of the latest solar storm, hoping to witness another rare celestial spectacle.
