NASA Discovers Sunspot Cluster, Risk Rises for a Fried Power Grid

NASA has identified a large cluster of sunspots or dark spots on the sun that have grown in size over the last month and could increase the risk of the Earth experiencing strong solar flares. 

NASA found the sunspot cluster known as AR3576 in late January from photographs taken by NASA’s Perseverance rover on Mars, according to Fox News

The magnetic fields of sunspots are thousands of times more powerful than Earth’s. 

As CBN News recently reported, the sun’s surface is growing more active, and serious anomalies can happen when that takes place. While that’s great news for amateur astronomers who are set to see some amazing solar fireworks through their telescopes, it could be bad news for power grids and communication satellites circling the Earth.

Solar flares occur when magnetic energy builds up in the solar atmosphere and is released in an intense burst of electromagnetic radiation, according to

This burst of energy can impact radio communications, electric power grids, navigation signals and pose risks to spacecraft and astronauts. 

On Friday, NASA’s Sun and Space X account posted a video showing the sunspots. The spots are usually as large as the Earth. But AR3576 is more than 93,000 miles long or nearly four times the circumference of our planet and more magnetically complex. 

NASA also announced the sun released a strong solar flare on Friday. This flare was classified as an X3.3 flare. The agency classifies solar flares from the smallest or B-class, followed by C, M and X, the largest or most intense. The number following the letter signifies its strength.

Luckily, this time, Earth wasn’t in the solar flare’s path

“Goodness knows how big this flare would have been if it had happened this side of the sun,” solar physicist Keith Strong wrote in a post on X

But this doesn’t mean the Earth wasn’t affected. The X-class flare caused extensive radio blackouts. Traveling at the speed of light, the radiation reached Earth in just over eight minutes, causing shortwave radio blackouts on the sunlit portion of the planet, which included South America, Africa and the Southern Atlantic, according to

The U.S. space agency on Sunday posted its weekly space weather report to X, along with a little more than three-minute video of the sun’s activity over the past week. 

“Happy #SunDay!” NASA wrote. “This week’s space weather report includes:
· 4 C-class flares
· 20 M-class flares
· 19 coronal mass ejections
· 0 geomagnetic storms

It’s the Coronal Mass Ejections (CME) that hurl charged matter out across the solar system like a giant shotgun, resulting in a potentially disruptive solar storm.
