摘要

Forecasting space weather is a guessing game. Predictions of outbursts from the sun are typically based on the amount of activity on the sun's roiling surface. But a new technique predicts the violent eruptions of radiation known as solar flares based on the physics behind them, researchers report in the July 31 Science. When applied to old data, the method predicted several powerful flares, though it also missed some. Radiation released in solar flares and associated eruptions of charged particles, or plasma, can disrupt radio communications, throw off satellites, take down power grids and endanger astronauts (SN: 9/30/17, p. 6). More accurate forecasts could allow operators to switch off sensitive systems or otherwise prepare. Current prediction methods rely on tracking flare-linked phenomena such as sunspots, dark regions on the sun's surface with powerful magnetic fields. But that leads to some false alarms.
