Sunspots AR3664 and AR3663 have been erupting with X- and M-class solar flares. Both sunspots are Earth-facing and could potentially deliver a solar storm. NASA's Solar Dynamics Observatory captured the fireworks.

X1.9-rated solar flare erupted from sunspot 4341 on January 18, causing R-3 radio blackouts.

Aurora alert! The colossal solar storm could impact and trigger impressive northern lights.

NOAA confirmed an X-class solar flare originating from Active Region 4341 on the Sun on Sunday, Jan. 18.

STUNNING Northern Lights could fill the night sky over the UK tonight after a powerful mass was splurted from the sun. A coronal mass ejection (CME) was ejected from the sun and is expected to

The massive sunspot that sparked an "extreme" geomagnetic storm in May 2024 unleashed hundreds of other dangerous solar flares, including a hidden X-class outburst, a new paper reveals. The study sets a record for the longest continuous observation of a single active region on our home star.

The northern lights may be seen in Massachusetts tonight as an X-class solar flare could cause a severe geomagnetic storm.

A strong solar storm has once again impacted the earth today which could lead to some viewing opportunities for the northern lights in our area.
