Sun Unleashes Powerful X-Class Solar Flare, NASA Captures Video

• The Sun emitted a powerful X1.9 solar flare on January 18, peaking at 18:09 GMT, captured by NASA’s Solar Dynamics Observatory.
• X-class flares are the strongest type of solar activity, originating from sunspot region AR4341.
• Solar flares can disrupt radio communications, navigation signals, and electric power grids.
• The flare was followed by a coronal mass ejection (CME), a massive release of solar plasma heading towards Earth.
• A G4-level geomagnetic storm, the strongest in over 20 years, impacted Earth, affecting satellites, space missions, and astronauts.

Why It Matters: A powerful X-class solar flare and subsequent geomagnetic storm, the strongest in two decades, hit Earth.
