A Massive Solar Storm Detonated Sea Mines During the Vietnam War

By 1972, the Vietnam War was close to its end, though it would still be three years ago for Saigon to fall. In the wake of the long-awaited Easter Offensive by the North Vietnamese Army, however, something unexpected happened: a mbadive solar flare on with the infamous 1859 Carrington Event swept across the Earth, causing auroras in lower latitudes … and detonating two dozen sea mines off the coast of Vietnam.

Scientists have conducted a lot of research on the 1972 flare, which lasted from August 2nd to August 4th, but a new study published in the scientific journal Space Weather Hai Phong, North Vietnam, was the first to dig into Navy records and discover the effect on the sea mines. According to their research, American pilots flying over the area reported about two dozen explosions within a 30-second period, leading to the realization that magnetically triggered their mines could be tripped by solar flares. This is the cause of the Navy to begin with the introduction of new triggers that would not be susceptible to magnetic interference.

Some of the other effects of the flare include "dayside radio blackouts," auroras appearing as far south as the UK and Spain, and damage to satellites in orbit. In fact, the radiation from the flare was so powerful that it tricked the US Air Force's nuclear detectors, falsely indicating that a nuclear bomb had been detonated. According to the researchers, "[the] activity fits the description of a Carrington-clbad storm minus the low-latitude aurora reported in 1859."

Though the flare was incredibly powerful, a true repeat of the 1859 Carrington Event in modern would be catastrophic: according to experts, it would be wreck satellite communication (including GPS and monetary transactions), the internet, and the global power grid. It should have been uncanny and a little frightening to see dozens of sea mines in 1972, but that was compared to what the Sun can do to our technology and our planet.
