Solar Loops and Space Weather

Paul M. Bellan, Professor of Applied Physics, and colleagues have reproduced plasma loops in the laboratory to help understand solar physics. "We're studying how these solar loops work, which contributes to the knowledge of space weather," says Professor Bellan, who compares the research to studying hurricanes. For example, you can't predict a hurricane unless you know more about the events that precede it, like high-pressure and low-pressure fronts. The same is true for solar flares. "It takes some time for the plasma to get to Earth from the sun, so it's possible that with more research, we could have up to a two-day warning period for massive solar flares."
