A powerful flare that occurred on the Sun on December 15 disrupted radio broadcasts on Earth. The flare affected Earth’s magnetosphere, preventing the propagation of radio waves.
The eruption, a plasma burst reaching approximately 1 million kilometers above the Sun’s surface, generated a strong magnetic wave heading toward Earth. Upon reaching Earth’s atmosphere, this wave disrupted radio waves, causing communication interruptions.
The flare particularly affected high-frequency radio signals, temporarily disabling shortwave radio broadcasts and satellite communication in North America and Europe.
For instance, in major cities like New York and Washington, DC on the east coast of the United States, some radio stations had to halt their broadcasts for a few hours. Additionally, some satellite TV channels and internet-based radio stations also temporarily ceased transmissions.
Moreover, the flare triggered the formation of auroras or the Northern Lights. Auroras result from charged particles from the Sun interacting with Earth’s atmosphere. The eruption increased the amount of charged particles reaching the atmosphere, making the Northern Lights brighter and more widespread.
The Sun regularly produces flares and plasma eruptions that can impact Earth’s atmosphere, disrupting communication, electrical grids, and satellites.
Scientists anticipate an increase in solar activity until 2025. Therefore, the likelihood of experiencing larger and more powerful solar flares in the coming years is plausible.
