Study Finds Coronal Loop Flickers Could Predict Solar Flares Hours in Advance
For years, scientists have sought methods to predict solar flares, the intense energy bursts from the Sun capable of disrupting technology and posing risks to astronauts. Using NASA's Solar Dynamics Observatory, researchers have identified brightness fluctuations in coronal loops—arch-like plasma structures in the solar atmosphere—that may provide advance warning of strong solar flares. These findings could enhance safety measures for space missions and safeguard technology affected by space weather disturbances. Findings on Coronal Loops and Solar Flares According to a study published in Astrophysical Journal Letters and presented at the American Astronomical Society meeting, the research led by Emily Mason of Predictive Sciences Inc. analysed coronal loops in areas preceding 50 major solar flares. Significant brightness variations in extreme ultraviolet light were observed in loops above active regions compared to those in non-flaring zones. This flickering reportedly intensif...
