Physicists classify them into three categories: C – the weakest, M – medium, X – the strongest.
On Thursday, December 14, the sun experienced its strongest flare since September 2017. This was recorded by NASA’s Solar Dynamics Observatory. Space reported it.
It is known that the class X flare occurred at 17:02 GMT or 19:02 Kyiv time.
Powerful flares are often accompanied by coronal mass ejections (CMEs), which send huge clouds of solar plasma into space at speeds of millions of kilometers per hour.
This outbreak is likely to be no exception. Its ejection speed can exceed 2100 km/s.
When CMEs enter Earth, they can cause geomagnetic storms that can knock out power grids and other infrastructure. Such storms can also supercharge auroras, making them more intense and visible over larger areas.
Earth’s atmosphere prevents harmful radiation from solar flares from reaching the earth. But this radiation can still affect our lives – for example, our health.
The number of sunspots was previously reported to have reached a 20-year high, indicating that the Sun is rapidly approaching its explosive peak.
