The Sun Does Something Weird Right Before It Unleashes Solar Flares

Flickering coronal loops in the Sun's outer atmosphere could act as an early warning system for solar flares, according to new research.

Flickering coronal loops can predict solar flares

New Delhi: Solar flares are intense bursts of radiation unleashed from the Sun that have been notoriously challenging to predict. Scientists have now proposed a new method that could be used to accurately predict solar flares, by tracking the flickering of coronal loops, or arch-like structures that extend through the outer atmosphere of the Sun. The coronal loops arise from clusters of sunspots with tangled magnetic fields, where solar flares o…

Scientists discover that large, dangerous solar flares are preceded by flickering loops

For decades, scientists have struggled to accurately predict solar flares—intense bursts of light from the Sun that can send a surge of charged particles into the solar system. Now, signals that precede these flares have been detected.NASA’s Solar Dynamics Observatory captured this image of coronal loops above an active region of the Sun in mid-January 2012. The image was taken at the 171-angstrom wavelength of extreme ultraviolet light. Credit:…

A team of researchers from the private company Predictive Sciences, which studies solar physics and forecasts space weather, has developed a method for predicting strong solar flares 2-6 hours before they occur. This discovery was made possible thanks to data obtained from NASA's Solar Dynamics Observatory (SDO). Heliophysicist Emily Mason led a team that studied in detail the coronal loops that emerge... The post Astrophysicists "translated" th…
