NASA spacecraft reveals the cause of radio signal loss in the Pacific Ocean

A very powerful explosion ionized the upper part of the Earth's atmosphere, leading to disruption of shortwave radio signals .

According to Live Science, the US Oceanic and Atmospheric Administration (NOAA) has just provided an answer for the radio wave disruption incident that recently occurred in the Pacific Ocean.

It is a "fire bomb" fired by the Sun since March 28. After a few days of travel, powerful electromagnetic radiation from this "fire bomb" hit the Earth's magnetosphere, causing problems with the radio communication system.

This conclusion was reached thanks to images from the Solar Dynamics Observatory (SDO), a NASA spacecraft circling our parent star.

In the photo, a very strong spot of light flashes from the surface of the Sun. That was the moment the "fire bomb" was fired.

It was a flare of magnitude X1.1 , one of the most powerful ever to burst from the Sun. The time it started emitting from the Sun was 4:56 p.m. March 28 (US time), corresponding to 4:56 a.m. March 29 Vietnamese time.

Taking into account the time it took for this firebomb to reach Earth, the loss of radio waves in the Pacific was entirely appropriate.

This flare was also accompanied by a coronal mass ejection (CME), which can be understood as a large fireball made of plasma.

NOAA predicted it would miss Earth, but what happened next showed that whether it missed or not, the fireball and its accompanying flare clearly caused a powerful geomagnetic storm.

Earth is likely to be hit even harder in the coming days, as the Sun enters the peak of its 11-year cycle.

However, it is still a natural phenomenon. It is also difficult for humans to directly feel the impact of geomagnetic storms, but aerospace operators may need to monitor space weather more closely, because it also has some influence on navigation systems. , television.
