A SOLAR STORM is expected to smash into Earth’s magnetic field tomorrow – here’s what you need to know.
Tomorrow, a “slow-moving” coronal mass ejection (CME) will strike Earth, experts from Space Weather said.
“The CME was hurled into space by an unstable filament of magnetism, which erupted on July 15th,” SpaceWeather reported.
One expert, Dr. Tamitha Skov noted that the impact from the “direct hit” could even be noticeable sometime today.
Space Weather predicts that this solar flare could lead to a G1-class geomagnetic storm.

What are solar flares and CMEs?
A solar fare is an eruption of intense high-energy radiation from the sun’s surface. A CME is a type of solar flare
When solar flares hit Earth’s magnetic field, they are called ‘solar storms’.
This occurrence can then lead to geomagnetic storms.

What are geomagnetic storms?
Geomagnetic storms are defined as “a disturbance of Earth’s magnetosphere that occurs when there is a very efficient exchange of energy from the solar wind into the space environment surrounding Earth,” per NOAA.
“These storms result from variations in the solar wind that produces major changes in the currents, plasmas, and fields in Earth’s magnetosphere.”
These types of storms are graded by severity on the G-Scale from G1 to G5, with the latter being the most powerful.
Geomagnetic storms that rank at a level 1 on the G-Scale don’t harm humans on Earth but can cause minor disruptions to power grids and satellite operations.
Meanwhile, a G5 storm – which is quite rare – is considered ‘extreme’ and can be very powerful.
Dr. Skov believes that tomorrow’s geomagnetic storm may also produce stunning auroral displays.
What are auroras?
Aurora borealis, also known as the Northern Lights, is the result of electrically charged particles from the sun, smashing into gaseous particles in our planet’s atmosphere.
The massive burst of material from the sun prompts a geomagnetic storm, which brings the aurora to lower latitudes.

Solar storms cause bright, colorful dancing lights in white, green, pink, and purple that illuminate the sky and are considered an incredible sight.
Color variations occur when different types of gas particles collide with the charged particles.
