What is the definition of a solar storm?
SOLAR storms can have a significant impact on both the Earth and the atmosphere.
On October 12, 2021, a solar flare is anticipated to impact Earth, causing widespread anxiety – so what do we know about them?
A geomagnetic storm, sometimes known as a solar storm, is a transient disruption of the Earth’s magnetic field induced by solar radiation and charged particle streams.
The storms happen when the sun releases massive bursts of energy and a flash of heightened brightness in the form of solar flares and “coronal mass ejections” (CME), which are charged plasma streamers that travel at millions of miles per hour.
At a speed of roughly 3,000mph, these discharge a stream of electrical charges and magnetic fields towards the Earth.
Solar flare frequency appears to follow an 11-year solar cycle, according to scientists. The Earth is at the beginning of a new cycle.
When a solar storm hits, it usually results in a stunning “Northern Lights” display in sections of the atmosphere visible near the Arctic Circle.
As the solar flare approaches Earth, it causes the aurora to move to lower latitudes, allowing the beautiful green colour to be seen from the United Kingdom.
Solar storms produce vivid, colorful dancing lights in white, green, pink, and purple that light up the sky and are a spectacular sight to see.
When different types of gas particles collide with charged particles, color differences arise. Green is the most prevalent aurora color, which is produced when oxygen molecules 60 miles above the ground react with the particles, whereas nitrogen produces a blue or purple hue.
The lights are best seen at the magnetic poles of the northern and southern hemispheres, and they are known in the south as the “Aurora Australis” or “southern lights.”
A solar flare can damage the Earth’s atmosphere, disrupting radio transmissions, power systems, and causing auroras to shift.
The “moderately intense” category G2 geomagnetic storm in October 2021 has prompted worries that it could disrupt power supplies.
According to the Met Office and the National Oceanic and Atmospheric Administration in the United States, it might hit Earth about 5 p.m. BST (12 p.m. ET) today.
It could also cause satellite communications to be disrupted, causing “orientation abnormalities.”
The magnetic field of the Earth helps to protect humans from the more severe effects of solar flares.
They can be deadly for an astronaut if they cause harm or interfere with mission control communications, in addition to causing problems for our technology on Earth.
Strong solar flares are divided into three groups by scientists:
