A sudden, intense burst of energy and radiation from the sun's surface, often associated with sunspots and solar activity.
During the solar flare, radio communications on Earth were temporarily disrupted.
The intense radiation from the solar flare interfered with radio signals.
Scientists monitor solar flares to predict their impact on satellites and power grids.
Researchers track solar flares to anticipate potential damage to technology.
Solar flares are classified by their X-ray brightness into categories: A, B, C, M, and X, with X-class being the most powerful.
Remember: A solar flare is a sudden burst of light and energy, while a coronal mass ejection (CME) is a slower-moving cloud of plasma. Both can disrupt technology but on different timescales.
Solar flares can disrupt radio communications, damage satellites, and even affect power grids on Earth, especially during strong events.
Compound of 'solar' (from Latin *solaris*, meaning 'of the sun') and 'flare' (from Old English *flear*, meaning 'a sudden burst of light or flame'). The term emerged in the early 20th century as astronomers observed and documented solar activity.
Solar flares are often confused with coronal mass ejections (CMEs), but they are distinct phenomena. A solar flare is a sudden flash of light, while a CME is a massive bubble of plasma ejected from the sun.
