Shining loops of plasma on the surface of the sun"flicker" hours before they unleash potentially dangerous solar flares, a new study shows. The new findings could help create more reliable space weather forecasts, researchers say.
Researchers analyzed SDO footage of the coronal loops preceding 50 solar flares. This video shows the flickering in a loop from 2011 in four different wavelengths of ultraviolet.The researchers noted that this flickering could"signal oncoming flares two to six hours ahead of time with 60 to 80 percent accuracy," which is a significant improvement over current methods. The intensity of the flickering also correlates with the power of the incoming flares, they added.
