What is a solar flare?

A solar flare is an intense burst of radiation caused by the sudden release of magnetic energy from the Sun's atmosphere, primarily in regions around sunspots.

How do solar flares affect Earth?

Solar flares can cause temporary disruptions to radio communications, GPS signals, and power grids by interacting with Earth's ionosphere and magnetosphere. They do not directly harm humans on Earth's surface.

Are solar flares dangerous to humans?

No, the radiation from solar flares is absorbed by Earth's atmosphere, preventing direct harm to humans on the surface. However, astronauts in space may face radiation risks.

What is the difference between a solar flare and a Coronal Mass Ejection (CME)?

A solar flare is a burst of radiation, while a CME is a large expulsion of plasma and magnetic field from the Sun's corona. Flares can often accompany CMEs, but they are distinct phenomena.

How are solar flares measured?

Solar flares are classified by their X-ray brightness, typically using a letter (A, B, C, M, X) indicating intensity, with X-class being the most powerful. Sub-classes (e.g., X1.0) further refine their strength.
