Active Region 2673 (AR 2673) blasted out yet another solar flare early this morning (Sept. 8), its sixth intense burst of high-energy radiation since Monday (Sept. 4). The latest flare, which peaked at 3:49 a.m. EDT (0749 GMT), registered as an M8.1 on scientists' three-tiered classification scale. ("C" flares are the weakest of the three, "M" flares are 10 times stronger than C's, and "X" events are 10 times more intense than M's. There is gradation within each category, too: An M8 flare is eight times stronger than an M1, for example.) [The Sun's Wrath: Worst Solar Storms in History]...

This flare was classified as an X2.2-class flare. ... This flare was emitted from Active Region 12297 (AR12297) on the sun. According to the US Space Weather Prediction Centre (SWPC) in Boulder, Colorado, the flare caused an hour-long blackout in some high-frequency radio communications over some areas.

FTA: "The model developed by the team could help scientists better understand the 11-year solar cycle and improve the forecasting of space weather, which can disrupt GPS and communication satellites as well as dazzle night sky watchers with auroras."

A solar flare measured at X8.7 on the strength scale just emerged from AR 3664, the sunspot region responsible for last weekend's solar storms that sparked vivid auroras.That's the most powerful solar flare of the current cycle, absolutely the most powerful since 2017, and comfortably within the top 20 solar flares ever measured.As AR 3664 made its way toward the edge of the Sun's disk, it wasn't just the X8.7 flare on May 14 that erupted from the solar limb. On May 15, an X3.4 flare followed suit, suggesting that the giant sunspot region is going to continue its party...

A powerful solar storm will make the northern lights visible to most of America — including the New York City area — Friday night, but you’ll need to get out of the city if you want a chance at seeing the auroras. The National Oceanic and Atmospheric Administration (NOAA) has upgraded the looming geomagnetic solar storm to a level 4, which is capable of disrupting America’s electrical grid and making the northern lights visible as far south as Alabama. The key to witnessing the natural phenomena will depend on the amount of cloud coverage and light population, making upstate New...

'NOAA's Space Weather Prediction Center (SWPC)- a division of the National Weather Service - is monitoring the sun following a series of solar flares and coronal mass ejections (CMEs) that began on May 8,' the emergency alert read. 'Space weather forecasters have issued a Severe (G4) Geomagnetic Storm Watch for the evening of Friday. 'Additional solar eruptions could cause geomagnetic storm conditions to persist through the weekend,' it went on, before describing the abnormal activity that tipped space specialists off. 'A large sunspot cluster has produced several moderate to strong solar flares since Wednesday at 5:00 am ET,' it read....

"This was a powerful blast - More info to come on what sort of impact we should expect here on earth! This marks the 4th X-flare since May 3rd (X1.6, X1.2, X1.2, X4.5), making AR3663 the most active sunspot of Solar Cycle 25 so far."

The solar flare is the most powerful eruption from sunspot region R3654 yet. Last night (April 30), the sun released an extremely powerful solar flare triggering widespread radio blackouts across the Pacific region. The flare peaked at 7:46 p.m. EDT (2346 GMT) and ended shortly after at 7:58 p.m. EDT (2358). Solar flares are eruptions from the sun's surface that emit intense bursts of electromagnetic radiation. They are created when magnetic energy builds up in the solar atmosphere and is released. Solar flares are categorized by size into lettered groups, with X-class being the most powerful. Then there are M-class...

On June 20, 2013, an area on the Sun’s surface erupted, sending out a coronal mass ejection (CME) that propelled billions of tons of charged particles into space. The storm reached Earth about two days later. Most of us didn’t even notice. We were busy watching the Miami Heat beat San Antonio Spurs, 95-88 in Game Seven of the NBA Finals. If we weren’t into basketball, we may have been surprised to hear that Senator Lisa Murkowski (R-Alaska) had became the Senate’s third Republican to publicly endorse same-sex marriage. Behind our backs, the Sun was churning out a storm of...

A massive solar flare exploded from the sun today, the largest of three X-class flares that have impacted Earth in the last 24 hours, and the most intense flare of the current solar cycle. Due to this event, there are significant high-frequency radio black-outs today and it is likely geomagnetic storm conditions will be likely around Earth in the coming days. This most recent X class flare is rated as a X 6.3. It generated an R3 radio blackout, which is considered “strong” on a 5-point scale, where R1 is “minor” with weak or minor degradation of HF radio communications...

(NEXSTAR) — A massive solar flare — the largest in years — was spotted on the sun on New Year’s Eve, sparking a warning to some high-frequency radio users. In an update Sunday evening, NOAA’s Space Weather Prediction Center (SWPC) released an image of the flare, which appeared as a large, glowing spot on the sun. You can see that image below. “A flare is an eruption of energy from the sun that generally lasts minutes to hours,” the SWPC explains. This one in particular, which peaked just before 5 p.m. ET on Sunday, was categorized as an X5 flare....

Though you can’t tell it with the unaided eye from here, the sun is incredibly active. A massive nuclear reaction hurtling through space, sometimes it and its sunspots are more active, meaning they emit more heat and radiation, and sometimes they are less active. Further, it can let fly with plasma, superheated matter, that distorts Earth’s magnetic field and can destroy electronics. That sun activity, called Coronal Mass Ejection (CME), is incredibly dangerous for electronics, many of which are quite fragile and, in the case of infrastructure, expensive and difficult to replace. That’s because the electric charge created by the...

Evidence of the most powerful solar storm in history has been uncovered in an unlikely place: within the rings of a tree. This immensely powerful solar storm is thought to have been at least 10 times as powerful as the Carrington Event of 1859, which caused chaos in the rudimentary telegraph system of the time. The researchers found a strange spike in radiocarbon within the rings of subfossilized trees dating to around 14,300 years ago. "Fusa Miyake discovered a sudden and unexpected spike in radiocarbon levels in a Japanese tree from 774 AD. Initially, this was thought to have been...

Experts have warned that the dark region, which is cooler than the surrounding area, could release energetic explosions capable of knocking out our planet's power grids. The exact measurements of the sunspot are unknown, but NASA's Perseverance rover snapped images of the spot as it sits more than 152 million miles from the sun. The rover observed the sunspot on August 17 through August 20 while exploring the Jezero Crater on the Red Planet.

A powerful solar flare disrupted radio and navigation signals across North America. on Monday (Aug. 7) and prompted space weather forecasters to issue warnings because of energetic particles hitting Earth. The flare, classified as an X1.5, was the 20th X flare — the most potent solar flare category — of the current 11-year solar cycle, which will reach its maximum next year.

Tiny spheres of once-molten metal magnetically dredged from the seafloor could be pieces from IM1, a potential interstellar meteor that struck Earth in 2014 Over the past two weeks, I have circumnavigated the globe by land, air and sea. The reason? A kitchen sink–sized chunk of interstellar material that my colleagues and I believe collided with the Earth at 100,000 miles per hour nearly a decade ago. After years of effort, we may have finally found pieces of this elusive object on the bottom of the Pacific Ocean, about a mile beneath the waves. The story began In April 2019,...
