Boulder, CO – A powerful X7.1 solar flare erupted from the sun on Sunday, October 1, 2024. The flare, originating from NOAA’s Region 3842, has raised concerns about possible disruptions to high-frequency (HF) radio communications and an increase in aurora sightings worldwide.
According to NOAA’s Space Weather Prediction Center, the flare began at 9:58 p.m. UTC and peaked at 10:20 p.m. UTC. Solar flares are bursts of radiation from the sun that can affect Earth’s atmosphere, leading to communication and navigation system issues. Additionally, solar flares often intensify auroral activity, making the northern and southern lights visible farther from the poles.
The flare may cause temporary degradation or complete loss of HF radio signals on the sunlit side of Earth. These interruptions could affect aviation, maritime operations, and emergency communications. Increased aurora activity has already been reported in northern Europe and North America, with more sightings expected globally.
NOAA continues to track the situation and will provide updates as needed. While solar flares pose no direct harm to humans on Earth, they can disrupt technology and infrastructure. For skywatchers, this event could offer a rare opportunity to witness auroras in areas where they are not typically seen.
