How Earth's Magnetic Field Twists during Solar Storms
Declassified Vietnam War files are showing researchers the unpredictable nature of the Sun and helping them work toward predicting the next big solar storm.

Traveling at the near-speed of light, energetic particles shooting out from the Sun can zip through space, smack into our planet’s atmosphere, and cause incredible disruptions. And one of the biggest impacts we know of happened during the tail end of the Vietnam War.
On this episode of Focal Point, we hear from Delores Knipp, a space weather scientist and former officer in the U.S. Air Force who uncovered a war mystery that is now connected to a major solar event. And Howard Singer, the chief scientist at the NOAA Space Weather Prediction Center.
In 1972, a solar flare, or solar storm, traveled at about 2,800 kilometers per second, which was seven times faster than the norm, and it carried tremendous magnetic field, and mass with it. A dozen sea mines exploded and everyone chalked it up to Vietnam warfare, but it was actually the solar flares. The bits of Sun slammed into the Earth’s magnetosphere within 15 hours and triggered the sea mines.
So how much do we know about solar flares and what's the chance another event could happen again? Learn more on this episode of Focal Point.
