US EditionSun Appears to Grin as Temperatures Set to Rocket
- A powerful M8.46-class solar flare erupted from sunspot region 4114 on June 15, 2025, causing radio blackouts across North America, Canada, Greenland, and parts of South America.
- This event followed earlier activity in May 2025, including an X2.7-class flare from sunspot AR 4087 on May 14, which was moving toward Earth alignment and triggered global radio blackouts.
- The June flare also produced a coronal mass ejection whose main plasma missed Earth, but a smaller fragment is expected to impact between June 17 and 18, likely causing a mild G1-class geomagnetic storm.
- NOAA officials reported a near-100% chance of repeated M-class flares this week and a 20% chance of a stronger X-class flare while advising satellite and infrastructure operators to remain alert.
- Experts noted the current solar activity poses limited risk to global infrastructure but may cause communication disruptions and enhanced auroral displays in Arctic and sub-Arctic regions during the geomagnetic storm.
