Incredible Solar Tornado: What It Means for Earth
Written on
Chapter 1: The Enormous Solar Tornado
Recently, a massive tornado, measuring ten times the size of Earth, erupted on the Sun. This extraordinary event has raised questions about its implications for our planet.
A remarkable tornado has been detected on the Sun, likely the largest ever recorded. Simultaneously, a substantial coronal hole has formed on the solar surface, allowing for the aurora borealis to be visible today in select northern regions.

Solar observation enthusiasts have a reason to celebrate as several unusual phenomena have emerged on our star. Last week, a filament of hot plasma began to rise from the Sun’s north pole, growing for three days until it reached a staggering height of 120,000 kilometers on Saturday, March 18. This height is equivalent to stacking nine and a half Earths on top of each other. This solar tornado, possibly the largest observed, was captured by NASA’s Solar Dynamics Observatory (SDO), which produced a stunning video showcasing the elongated, bending plasma.
What Exactly Are Solar Tornadoes?
Solar tornadoes are formed from heated plasma that takes on unique shapes due to the Sun's magnetic field. These phenomena typically occur at the poles, where the magnetic field lines are open. The magnetic field in the lower layers of the Sun’s atmosphere carries electrically charged gas, which distorts the field's lines of force higher up, creating a vortex that escapes through the open magnetic field lines. A solar tornado can also be referred to as a protuberance or solar filament, and these can appear several times throughout the year. The frequency of such events is influenced by the solar cycle, with more occurrences expected as the solar maximum approaches in mid-2025.
Chapter 2: Current Solar Activity
As for the tornado observed recently, it has already dissipated, ejecting material from the Sun’s atmosphere into space. Fortunately, it did not have any direct impact on Earth. However, there are currently six sunspots visible on the Sun's surface, with the largest one posing a potential source of solar flares.
Solar flares can significantly disrupt satellite operations and lead to failures in communication and power networks on Earth. Nevertheless, the strongest flares typically occur only once per solar cycle, while weaker flares might only cause minor radio transmission issues near the Earth’s poles.
In addition to the sunspots, there are currently two coronal holes present on the Sun. These cooler areas in the upper atmosphere allow solar wind to escape into space. The larger hole could fit 20 to 30 Earths side by side, and its presence will likely result in the visibility of the aurora borealis on Earth. For the best views, one would need to travel from Poland to northern regions like Sweden and Finland, while residents of the northern United States will have a great opportunity to witness the aurora.
The Sun’s activity is expected to induce a geomagnetic storm, although it is anticipated to be weak and pose no threat to Earth’s electronic systems.
