Geomagnetic solar storm on Earth: Everything you need to know

Meteorologists are predicting a G1-level storm - the lowest level on the solar storm scale, which peaks at G5.

Charged, magnetic particles from the solar storm can interfere with machinery in Earth's orbit as well as at the planet's surface, such as GPS systems and radio signals.

In recent days, several reports emerged of a geomagnetic storm purportedly due to hit Earth on March 18.

No, a massive geomagnetic storm will not hit Earth on March 18.

These events may be induced radiation or streams of charged, electrical particles at a speed of over 4 million kph. Over a century later in Canada, on March 13, 1989, a geomagnetic storm caused a major blackout in the country that lasted nine hours, disrupting electricity from the Hydro Quebec generating station and going as far as melting power transformers in New Jersey.

Solar flares occur when a build-up of magnetic energy on the sun is suddenly released. When the sun emits superheated plasma, otherwise known as a coronal mass ejection (CME), it can trigger a geomagnetic storm.

Retail inflation eases to 4.4% in February; IIP grows 7.5% in January
Food inflation, as measured by Consumer Food Price Index, rose to 4.96 per cent in December from 4.35 per cent the previous month. Excluding volatile food and energy prices, the CPI was up 0.2% for the month and 1.8% annualized, unchanged from a month ago.

A solar flare that erupted on August 4, 1972, knocked out long-distance communication across some U.S. states, according to NASA.

When a solar storm strikes it usually creates a spectacular "Northern Lights" display in parts of the atmosphere that can be seen in areas close to the Arctic Circle.

According to the SWPC, it's possible that the solar storm - which will occur when charged particles from the sun interacting with Earth's magnetic field - will cause "weak power grid fluctuations" and may have a "minor impact on satellite operations".

According to Thought & Co, "some experts have testified before Congress that space weather affects people's ability to make phone calls, use the Internet, transfer or withdraw money, travel by plane, train, or ship, and even use Global Positioning System to navigate in cars".

The strongest geomagnetic storm on record is the Carrington Event in 1859, aimed after Brit astronomer Richard Carrington, which electrified telegraph lines and shocked technicians, setting their papers on fire - it was visible as far as Cuba and Hawaii.

Scotland remains the best place to see the Northern Lights in the United Kingdom, given its closer proximity to the North Pole, and can be most visible in the Scottish Highlands and Scottish Isles. These northern lights were captured in Norway.
