Solar storm: UK alert as Earth faces ‘oblique blows’ – sun erupts with ‘dozens’ of flares | Science | New

Over the past week, Earth has been hit by a number of different solar storms one after the other, with some experts describing them as “machine gun” fire. Originally the outbursts were only expected to last a few days, but experts are now warning that the Sun has ejected a dozen more flares. A solar storm occurs when the Sun ejects powerful bursts of energy in the form of solar flares and coronal mass. ejections.

THIS IS A BREAKING STORY. MORE SOON

The Sun is currently at the peak of its 11-year cycle, known as solar maximum.

At this time, more sunspots emerge on its surface, and as a result, the number of space weather events such as solar flares and coronal mass ejections (CMEs) increases.

These sunspots appear darker than their surroundings on the surface of the Sun and can extend for hundreds of millions of kilometres.

Sunspots are the result of magnetic disturbances in the photosphere – the lowest layer of the sun’s atmosphere – these disturbances exposing the star’s cooler layers below.

In the past 24 hours alone, experts have warned that active sunspot AR3078 has ejected four M-class solar flares and more than a dozen C flares.

Space weather expert Dr Tamitha Skov tweeted: “This region just doesn’t stop! Such a gorgeous eruption.

“We could very well have more solar storm hits through August 21. Pattern patterns are changing rapidly!”

Spaceweather.com wrote: “The explosion ended with similar explosions hours earlier and later.

“Norway, Sweden, UK, Northern Europe – get ready.”

She added: “Expect sporadic auroras to mid-latitudes through August 20.

“Amateur radio disturbances are expected on the night side of Earth. GPS reception issues at dawn, dusk and near aurora.

Auroras are natural light shows generated when particles from the solar wind excite atoms in Earth’s upper atmosphere, causing them to glow.

When observed in the northern hemisphere, they are known as the aurora borealis, while their antipodal counterpart is called the aurora australis.

Auroras form curtains of light that follow geomagnetic field lines and appear in different colors depending on the excited atoms.

The two main gases in Earth’s atmosphere are oxygen, which emits a greenish light, and nitrogen, which appears in hues of blue, pink, and purple.
