Solar Maximum 2025 is the expected peak of solar activity in Solar Cycle 25, characterized by heightened sunspots, solar ...

NASA's Solar Dynamics Observatory captured sunspot AR3386 blast a long-duration X1.6-class solar flare and X1 flare. See time ...

An astrophotographer has captured an extremely rare and "difficult" photo of a solar flare exploding from the sun at the ...

In May 2024, the largest solar flare since 2017 was detected, ranking at an X-8.7 magnitude. Then in 2025, a flare May 13 was classified as an X-1.2 , and another the next day was listed as an X-2.7.

NASA reported sunspot region 4114 unleashed a powerful X1.2-class solar flare on June 17, disrupting shortwave radio communication, especially over the Pacific, including Hawaii. Frequencies below ...

It unleashed another M6.4 flare early on June 16 at 5:30 a.m. EDT (0930 GMT) and remains in an Earth-facing position. More solar flares — and possibly more CMEs — could erupt in the coming days.

X-class flares are the most powerful type of solar flare. Tuesday's event ranked as an X1.2, placing it at the lower end of the X-scale, but still strong enough to cause disruptions.

On June 15th, a significant M8.46 solar flare from sunspot region AR 4114 caused shortwave radio blackouts, particularly affecting the Americas. NOAA classified it as an R2 event, impacting ...

Captured by NASA’s Solar Dynamics Observatory, the flare was recorded at 11:50 pm UTC. Classified as an X1.9 solar flare, the blast ranked among the most extreme solar phenomena.

In May 2024, the largest solar flare since 2017 was detected, ranking at an X-8.7 magnitude. Then in 2025, a flare May 13 was classified as an X-1.2 , and another the next day was listed as an X-2.7.

NASA’s Solar Dynamics Observatory captured an image of the event, which could cause a series of radio and satellite blackouts across the U.S., according to NASA. Solar flares are powerful bursts ...
