Sun Unleashes Three Major Solar Flares, Boosting Northern Lights Chances
Sun Unleashes Three Major Solar Flares, Boosting Northern Lights Chances
US · Published Jun 4, 2026
In a dramatic display of solar activity, the sun has erupted with three significant solar flares within a 24-hour period, potentially sending multiple coronal mass ejections (CMEs) toward Earth.
The flares originated from sunspot region 4455, which is currently Earth-facing.

Why It's Important?

The solar flares have already caused radio blackouts of varying intensities. The M9.3 and M7.9 flares resulted in moderate R2 blackouts over East Asia, Australia, Europe, and Africa, while the X1 flare caused a stronger R3 blackout over Europe and Asia. The potential arrival of Earth-directed CMEs could lead to geomagnetic storms, with the U.K. Met Office issuing a strong (G3) geomagnetic storm watch for June 4-6. These storms may disrupt satellite operations, power grids, and communication systems, while also enhancing auroras, potentially visible at lower latitudes.
