Sunspot region 4114 has unleashed its most powerful solar flare yet — an X1.9 class that erupted late June 19, triggering shortwave radio blackouts across the Pacific Ocean, including parts of Hawaii.

Frequencies below 25 MHz were affected, impacting aviators and ham radio operators. Although a coronal mass ejection didn't accompany it, the flare's intensity disturbed Earth's ionosphere.

Ham radio operators around Hawaii may have noticed a loss of signal at frequencies below 25 MHz, according to spaceweather.com. Eric Lagatta is the Space Connect reporter for the USA TODAY Network.
