The sun is constantly releasing huge explosions of plasma into deep space. In this case, the particles emitted by the solar flare were directed directly at Earth, which led to technological problems on our planet.
As a result, when the flame occurred in the last hours of November 23, some radio frequencies were blocked.
Solar flares can be harmful to radio waves. When they strike the atmosphere, ionization occurs which drains the energy from the radio waves.
A video from NASA shows the impressive solar flare, as the sun appears to rise before exploding into life.
Astronomy website Space Weather said: “The Sunspot AR2785 erupted during the late hours of November 23 (2335 UT), generating a C4 solar flare.
The explosion threw a column of plasma more than 350,000 kilometers across the sun.
NASA’s Solar Dynamics Observatory recorded snowfall.
“A pulse of ultraviolet rays emitted by the glow struck the Earth, briefly ionizing the upper part of our atmosphere.
“This in turn caused shortwave radio dimming over the South Pacific, including eastern Australia and all of New Zealand. The affected frequencies were below 10 MHz.

When solar particles bombard the atmosphere, they can cause the planet’s magnetosphere to expand.
As such, it makes it difficult for satellite communications to penetrate the atmosphere, damaging technologies such as cell phones, satellite television, and GPS.
A recent study from the Skolkovo Institute of Science and Technology in Russia said: “A large solar storm can cut off electricity, television broadcasting, internet and wireless communications, leading to large cascading effects in many areas of life.
According to some experts, the damage from such an extreme event could cost up to several trillions of dollars and restore the infrastructure and economy could take up to 10 years.
“Thus, understanding and predicting the most dangerous extreme events is of the utmost importance in protecting society and technology from the global hazards of space weather.”
