Astronomers report sunspot AR4366, about 15 times the width of Earth, is facing our planet and has already produced multiple strong M- and X-class solar flares that can disrupt radio signals. The piece explains how to view the sunspot safely with proper solar eclipse glasses or filtered optics, noting AR4366 will remain visible for several days and could spawn more flares and geomagnetic activity.
Sunspot region 4366 has unleashed dozens of solar flares in 24 hours, including multiple M-class and X-class eruptions—the strongest since 2024—making it the most active sunspot in years. NOAA's SWPC says a coronal mass ejection is headed toward Earth but is likely to miss or only graze it, potentially sparking auroras at unusually low latitudes later this week.
A record-breaking study revealed that the giant sunspot AR 13664, which grew to 15 times Earth's width, produced nearly 1,000 solar flares, including powerful X-class flares, and triggered Earth's most intense geomagnetic storm in over 20 years, highlighting the sun's immense power during solar maximum.
Astronomers are monitoring a large sunspot cluster, Region 4274, which has produced multiple powerful solar flares, including X-class events, potentially impacting Earth's communications and power systems as the sun approaches its active peak in its 11-year cycle.
A new sunspot is producing magnetic explosions called Ellerman bombs and has already emitted multiple M-class solar flares, which could lead to increased space weather effects on Earth as it rotates into a position facing our planet.
A large, unstable sunspot (region 4114) facing Earth has emitted its strongest flare yet, an X.12 class solar flare, causing radio blackouts and disruptions, with more eruptions expected as the Sun is in its solar maximum phase. The flare was electromagnetic, not accompanied by a coronal mass ejection, and the region is predicted to remain active until it rotates out of view.
A powerful M8.46-class solar flare erupted from sunspot region 4114 on June 15, causing radio blackouts across North America and a coronal mass ejection that may impact Earth on June 18, potentially triggering northern lights and minor geomagnetic storms.
A powerful X2.3-class solar flare erupted from sunspot region AR 3883 on November 6, 2024, causing radio blackouts over parts of the Atlantic Ocean, South America, and Africa. Scientists are awaiting data to determine if a coronal mass ejection (CME) will impact Earth, potentially causing geomagnetic storms and auroras. The flare was classified as R3-Strong on the Space Weather Scale, indicating significant radio disruption. More solar flares are expected, with potential impacts ranging from minor to strong.
The sun has emitted its second powerful X-class solar flare this week from sunspot AR3738, causing shortwave radio blackouts over the Atlantic Ocean, Africa, Europe, and parts of the Americas. The flare, which occurred on July 16, 2024, may have also triggered a coronal mass ejection, though it is not expected to impact Earth directly. The sunspot is nearing a "danger zone" that could potentially send more charged particles toward Earth.
A massive sunspot named AR3738 is moving into a position where it could send a proton storm toward Earth, potentially damaging satellites and disrupting communications. The sunspot's volatile magnetic field could release solar flares or coronal mass ejections, posing risks to astronauts and high-altitude flights. If the sunspot doesn't explode soon, Earth will avoid these dangers.
An astrophotographer has captured stunning images of sunspot region AR3697, which is responsible for recent Northern Lights activity. This sunspot, known for causing solar flares and coronal mass ejections, is set to return, potentially leading to more solar storms and auroras.
The same sunspot that caused May's northern lights is back, potentially creating another solar storm between June 4-6. This could make the northern lights visible in northern and upper midwest states from New York to Idaho. Optimal viewing conditions are expected due to a new moon on June 6.
Astrophotographer Andrew McCarthy captured detailed images and timelapses of sunspot region AR3697, which recently caused significant auroras on Earth. His observations from Arizona reveal the dynamic nature of the sunspot, including plasma loops and solar flares. As AR3697 rotates to face Earth again, it may trigger more geomagnetic storms and auroras. McCarthy shares his work on social media, showcasing the intricate process behind his stunning solar images.
The hyperactive sunspot region AR3664 has unleashed two powerful X-class solar flares within 12 hours, causing radio blackouts across parts of the Earth. These flares, categorized as X1.18 and X1.43, resulted from magnetic reconnection in the sunspot's complex core. The flares impacted the Western U.S., Pacific, Europe, Africa, and Asia, disrupting shortwave radio communications.
A coronal mass ejection from a massive sunspot cluster could make the northern lights visible over parts of New England on Friday night. Although the geomagnetic storm is weaker than the one earlier this month, it may still allow for aurora sightings in some northern and upper Midwest states. Massachusetts skies are expected to be clear, but the aurora's visibility is uncertain. However, the sunspot can be seen as a dark dot on the sun using solar eclipse glasses.
