Massive Solar Storm Set To Hit Earth Today, Auroras May Be Visible From Parts Of India
A powerful solar eruption is heading towards Earth, prompting a strong geomagnetic storm watch. Scientists say the event could trigger spectacular auroras across several regions, including parts of northern India, if conditions align.
A massive solar eruption from the Sun is expected to reach Earth today, prompting space weather agencies to closely monitor its impact on the planet’s magnetic field.
The event began on June 6 when Active Region 4461 on the Sun produced an M1.8-class solar flare, releasing a dense and highly magnetised filament directly toward Earth. Scientists estimate the cloud of charged particles is travelling through space at around 1,400 kilometres per second.
As a result, the US Space Weather Prediction Center (SWPC) has issued a G3, or Strong Geomagnetic Storm Watch, while scientists have warned that storm intensity could briefly reach G4, classified as Severe, if conditions become favourable.
A geomagnetic storm occurs when powerful solar energy and charged particles interact with Earth’s magnetosphere, the magnetic shield that protects the planet from space weather.
The approaching solar cloud originated from a massive filament eruption on the Sun. Filaments are dense streams of plasma suspended above the solar surface by powerful magnetic fields. When these magnetic structures become unstable, they can erupt violently, launching huge quantities of magnetised plasma into space.
Scientists say this particular eruption was unusually dense and fast-moving, increasing the possibility of a stronger impact once it reaches Earth.
One of the most visible effects of the storm could be the appearance of auroras, popularly known as the Northern Lights, far beyond their usual polar regions. Auroras occur when charged solar particles collide with gases in Earth’s upper atmosphere, creating colourful displays of green, purple and red light across the night sky.
Space weather experts believe auroras may become visible across parts of northern India, central Europe, the northern United States, Australia and New Zealand if weather conditions remain favourable.
Researchers are paying special attention to a critical factor known as the Bz magnetic field orientation inside the incoming solar cloud. If this magnetic field points southward when it arrives, it can connect more efficiently with Earth’s magnetic field, allowing greater amounts of solar energy to enter the atmosphere.
The stronger and longer the southward Bz orientation lasts, the brighter and more widespread the auroras are likely to become.
Scientists also noted that the Sun has been particularly active in recent days, producing multiple eruptions and geomagnetic storms. There is a possibility that the incoming solar cloud could interact with material from earlier eruptions, creating what is known as a “cannibal CME”, where two solar clouds merge into a larger and potentially more powerful storm.
However, forecasters say the exact strength of the storm will not be known until the solar cloud passes monitoring satellites located about 1.5 million kilometres from Earth, providing only 15 to 60 minutes of advance warning before impact.
While the storm is not expected to pose a danger to people on the ground, it could create dazzling auroral displays and may temporarily affect radio communications, satellite operations and navigation systems if conditions intensify.
Disclaimer: Space weather forecasts can change rapidly depending on solar and geomagnetic conditions. Actual storm intensity and aurora visibility may vary from current predictions.
