NASA says May’s aurora may have been strongest in 500 years

According to one, the dazzling display of aurora on May 10/11 was one of the strongest on record in the last 500 years. statement From NASA.

In another record-breaking claim, the British Geological Survey claimed that the aurora display over Britain was the result of the most extreme and longest-lasting geomagnetic storm recorded in the last 155 years.

And there is a possibility that it could happen again.

“We will continue to study this event for years,” said Teresa Nieves-Chinchilla, acting director of NASA’s Moon to Mars (M2M) Space Weather Analysis Office. “This will help us test the limits of our models and understanding of solar storms.” The space agency said they were “possibly one of the strongest displays of aurora on record in the last 500 years.”

strike together

Due to solar superstorm on 10/11 May Aurora Borealis (Northern Lights) will be visible in the Northern Hemisphere as far as Florida, while southern dawn (Southern Lights) visible as far north as New Zealand.

NASA first detected the start of the solar storm on May 7, when two solar flares were detected. Seven stunning flares erupted over the next four days, all aimed at coronal mass ejections—clouds of charged particles—in Earth’s direction. They traveled at different speeds and arrived simultaneously,

“All of the CMEs came together and the conditions were absolutely perfect to produce a truly historic storm,” said Elizabeth McDonald, NASA’s Heliophysics citizen science lead and a space scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

Largest since 2003

According to the BGS, May’s geomagnetic storm – caused by a series of consecutive solar flares and the CMEs that followed them – shares characteristics with some of the biggest storms since 1869, the most recent being the 2003 Halloween geomagnetic storm. It said daily geomagnetic activity has been recorded since 1869.

Auroras are the result of the solar wind in space – charged particles from the Sun – that move rapidly beneath the field lines of Earth’s magnetic field.

The Earth’s geomagnetic field is compared using readings of its horizontal magnetic field intensity, which typically measure around 30-50 nanotesla (nT) meters, according to the BGS, in Lerwick, on the Shetland Islands in Scotland. On the evening of May 10, they peaked at 800 nT.

Aurora’s return?

The sunspot that caused the flare and the CME, called AR13364, is currently facing Venus, at which it unleashed a giant X12-class solar flare on May 20. It was the most powerful of the current solar cycle. As the Sun rotates toward Earth, AR13364 is expected to still be active, warning of more potentially powerful geomagnetic storms.

a new article published In Nature states that more powerful geomagnetic storms are expected in the next year or two as the Sun approaches “solar maximum,” the peak of its magnetic activity that occurs once every 11 years.

Wishing you clear skies and wide eyes.
