A solar flare from sunspot 4479 triggered a brief radio blackout over parts of North America and the Pacific. Forecasters are now tracking an Earth-bound coronal mass ejection that could bring a moderate to strong geomagnetic storm on July 2.
A strong solar flare of category X alerts specialists, after a powerful explosion in the Sun with 17 solar flares in one day. As a solar flare of category X is 10 times stronger than its previous category M on the algorithmic scale. In addition to this strong solar flare of category X alert, they can cause a severe geomagnetic storm with consequences on the Earth. A solar flare of category X arrives with 17 solar flares on a day This 30th of Jun…
A solar storm was recorded on Tuesday, June 30, 2026, according to the Space Weather Prediction Center (SWPC).
