NASA says strong incoming solar winds could spark geomagnetic storm on Earth

The Sun’s solar activity is increasing as we approach the peak of solar cycle 25. This 11-year cycle sees fluctuations in the Sun’s activity, with the lowest point known as the solar minimum and the period of highest activity known as the solar maximum. NASA’s Solar Dynamics Observatory has detected a strong stream of solar wind flowing towards Earth, potentially sparking a geomagnetic storm.

The solar wind, flowing at speeds of over 500 kilometers per second, has not yet caused a geomagnetic storm, but one could be on the way. Skywatchers in the Arctic regions should be on the lookout for auroras, also known as Northern Lights or Aurora Borealis, as a result of the solar activity. These mesmerizing lights are usually seen in the northern polar regions, but if the geomagnetic storm is powerful enough, they could be visible further southwards in places like the US and England.

NASA says strong incoming solar winds could spark geomagnetic storm on Earth – Detail Points

– Solar cycle 25 is nearing its peak, bringing increased solar activity
– Solar cycle is an 11-year period of fluctuating solar activity
– Solar minimum is the lowest point of activity, while solar maximum is the period of highest activity
– As we approach solar maximum, Earth is predicted to face more CMEs, sunspots, solar flares, and solar storms
– NASA’s Solar Dynamics Observatory has revealed a strong stream of solar wind flowing towards Earth
– This solar wind could spark a geomagnetic storm
– A sunspot complex named AR3490-91-92 has been observed on the solar surface
– The sunspot is slowly turning towards Earth and could hurl out solar winds
– A stream of high-speed solar winds is currently flowing towards Earth at speeds of over 500 kilometers per second
– While it has not sparked a geomagnetic storm yet, one could be on the cards
– Skywatchers in the Arctic regions should be on the lookout for auroras after nightfall
– Auroras, also known as Northern Lights or Aurora Borealis, are visible in the northern polar regions

What is a solar cycle?

A solar cycle is an 11-year period where the Sun’s activity dips and rises. The lowest point of activity in the cycle is known as the solar minimum, while the period of highest activity is known as the solar maximum.

What is a geomagnetic storm?

A geomagnetic storm is a disturbance in Earth’s magnetosphere caused by changes in solar wind. It can cause beautiful auroras in the polar regions and disrupt power systems, satellites, and navigation systems.

What are auroras?

Auroras, also known as Northern Lights or Aurora Borealis at the North Pole and Southern Lights or Aurora Australis at the South Pole, are shifting curtains of light in greens, blues, and pinks in the night sky. They are caused by the interaction between solar wind and the Earth’s magnetosphere.
