Sun sent 28 solar flares erupting through space in a week
The U.S. National Oceanic and Atmospheric Administration issued four radio blackout warnings in the past two days after solar weather suddenly turned turbulent.
Radiation from flares cannot penetrate Earth's atmosphere to harm life on the ground, but when intense enough it can disturb the atmosphere in the ionosphere, where GPS and radio signals travel.
Since October 23 the Sun has let loose with 24 medium-strength M-class solar flares, and four X-class flares - the most powerful kind.
In fact, with our local star heading towards the peak of its 11-year cycle, a period known as the solar maximum, this shouldn't be unusual. But lead up to the solar max has been unusually subdued this year.
Sources and more information:
The sun has erupted more than two dozen times over the last week, sending radiation and solar material hurtling through space - and scientists say more eruptions may be coming. This shouldn't be unusual. After all, we are technically at solar maximum, the peak of the 11-year cycle of the sun's activity.
More than two dozen solar flares have erupted from the Sun in the past seven days, catapulting radiation towards the Earth that could potentially play havoc with global communications. The U.S. National Oceanic and Atmospheric Administration issued four radio blackout warnings in the past two days after solar weather suddenly turned turbulent.
