Powerful X1.9-Class Solar Flare Disrupts Pacific Radio Signals
A massive X1.9-class solar flare erupted from the sun’s active region 4114 on June 19, peaking at 9:50 p.m. EDT. The flare caused a shortwave radio blackout over the Pacific Ocean, including parts of Hawaii.
Impact on Radio Communications
The electromagnetic radiation from the flare ionized the upper atmosphere, disrupting shortwave radio communication below 25 MHz. Ham radio operators in the Pacific region reported an abrupt loss of signals following the peak of the flare.
Solar Flare Details
- Classification: X1.9-class, one of the strongest in the current solar cycle
- Sunspot: Region 4114, known for its magnetic complexity and explosive potential
- Previous Activity: An X1.2 flare was recorded from the same region just days ago
Potential Future Risks
Although the latest flare wasn’t accompanied by a coronal mass ejection (CME), experts suggest future eruptions could be more geoeffective. If a CME is launched, geomagnetic storms and auroral activity may follow.
Staying Informed
Space weather forecasts and aurora updates are available on:
- NOAA’s 3-day geomagnetic outlook
- Dedicated solar activity blogs
What’s Next?
Moderate-to-low flare activity is expected in the coming days, with a 55% chance of M-class flares and a possibility of stronger X-class flares
