X class flares are the largest solar flares, according to a classification system which classifies flares according to their intensity.

Centeropoints are holes in the Sun’s upper atmosphere, where the plasma is less dense and cooler than in other parts of the solar system.

On a scale similar to storms occurring within Earth’s atmosphere, storms are measured, with each end depicting its risk to Earth, from mild to significant.

Two “large” solar flares have been watched in the sun with aurora borealis possible.

The G5 is the most dangerous while minor G1 hurricanes are expected to cause little variability in the electrical systems and “minor impact on satellite operations.”

While the sun’s magnetic field is largely closed, coronal holes have an open field extending into interplanetary space whereby solar winds can run of.


Earth

Earth is the third planet from the Sun and the only astronomical object known to harbour and support life. 29.2% of Earth’s surface is land consisting of continents and islands. The remaining 70. (wikipedia)


Moon

The Moon is Earth’s only natural satellite. At about one-quarter the diameter of Earth , it is the largest natural satellite in the Solar System relative to the size of its planet, (wikipedia)


Solar flare

A solar flare is a sudden flash of increased brightness on the Sun, usually observed near its surface and in close proximity to a sunspot group. Powerful flares are often, but not always, (wikipedia)
