Powerful solar flare erupts from sun triggering radio blackouts across North America

A powerful M-class solar flare (M8.46) erupted on June 15, the second strongest in the current solar cycle, and was followed by a coronal mass ejection that may reach Earth by June 18. The flare temporarily disrupted radio signals across North America, and the CME could trigger minor geomagnetic storms and visible auroras in northern U.S. states. Space.com reports that the event highlights the impact of solar activity on Earth's communication systems.
