Solar Storm June 11 2024. Last weekend, the biggest solar storm to hit earth in over 20 years swept over our planet as the sun’s activity ramps up to the peak of its current solar cycle. This phenomenon happens roughly every 11 years and marks an important stage in the solar cycle.

No g1 (minor) or greater geomagnetic storms are expected. A geomagnetic storm caused by solar flare activity could trigger numerous effects for life on earth this weekend, according to the national oceanic and atmospheric administration.
