Solar flares may show predictable warning signs hours before erupting
Recent observations suggest that solar flares may exhibit predictable warning signs hours before they occur. Scientists noted changes near the solar surface starting three hours prior to a significant solar flare. This research could enhance our ability to forecast solar activity and protect critical infrastructure on Earth.
- ▪The Solar Dynamics Observatory recorded a significant solar flare on October 3, 2024.
- ▪Changes near the solar surface were observed three hours before the solar flare erupted.
- ▪The findings could lead to improved predictions of solar flares, aiding in the protection of power grids and satellites.
