The sun's magnetic field will reverse its polarity three or four months from now, as it does every 11 years at the peak of the solar activity cycle. Researchers know enough about this process to predict when it will occur, but its causes remain mysterious
07 August 2013, 07:06 PM ET
The sun's magnetic field is set to reverse its polarity in the next few months. But the shift won't spark an increase in solar storms or other events that could have a damaging effect on Earth and its inhabitants, researchers say.
