The Sun constantly releases huge explosions of plasma into deep space. In this case, the particles released by the solar flare were aimed right at the Earth, leading to technological problems on our planet.
Consequently, when the glow struck in the last hours of November 23, some radio frequencies were blocked.
Solar flares can be harmful to radio waves because when they hit the atmosphere, ionization takes place which steals energy from radio waves.
A NASA video shows the impressive solar explosion, with the Sun appearing to boil before exploding into life.
Space Weather astronomy site said: “Sunspot AR2785 exploded during the last hours of November 23 (2335 UT), producing a C4-class solar flare.
“The blast sent a plasma plume over 350,000km across the sun.
“NASA’s Solar Dynamics Observatory recorded the splashdown.
“A pulse of ultraviolet radiation from the glow hit the Earth, briefly ionizing the upper part of our atmosphere.
“This, in turn, caused a shortwave radio blackout in the South Pacific, including eastern Australia and all of New Zealand. The frequencies affected were mainly below 10 MHz.

When solar particles bombard the atmosphere, they can cause the planet’s magnetosphere to expand.
As such, it makes it much more difficult for satellite communications to penetrate the atmosphere, damaging technologies such as cell phones, satellite television and GPS.
A recent study by the Institute of Science and Technology in Skolkovo, Russia, said: “A large solar storm could disrupt electricity, television broadcasting, the Internet and radio communications, leading to significant 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 the restoration of infrastructure and the economy could take up to 10 years.
“Therefore, understanding and predicting the most dangerous extreme events is of prime importance for the protection of society and technology against the global risks of space weather.”
