The Space Weather report may have solved the mystery of Vietnam War and discovered how much solar activity can hamper technology on Earth.
Now and then, Solar outburst (a strong magnetic energy explosion on the Sun's surface) and coronal mass excitement (Sun-emitted plasma clouds) can lead to sunstroke. Electromagnetic radiation emitted by them can interfere with communication systems. A new study examined the effects of one storm in 1972.
"In the beginning of August 1972, the extreme weather conditions in space had a significant impact on the US Navy, which is not widely reported," wrote the study team led by Delors Knip, Professor of Engineering in Colorado Boulder University. "These timely effects of the Vietnam War Archive show the severity of the storm: an almost immediate, unplanned detonation of dozens of nautical miles south of Hai Phong, North Vietnamese."
These American magnetic detonators were designed to turn them on when the ship came close. However, the solar storm, which occurred more than 90 million miles from the star, was enough to trigger it. In fact, according to the study, the electromagnetic pulse from coronal mass injections, which ultimately flew from the sea mine, reached Earth 14.6 hours (usually lasting up to two days). The study also noted that the storm's additional effects included radio switching off, visible aurors in the UK and Spain, and damage to solar panels in satellite orbit.
The newly-documented Navy documents reveal that officials have noticed that solar activity has caused sea bombs, but these entries were not fully tested until the space journal magazine Gizmodo was investigated. The authors of the study also called solar activity in 1972 – the "Carrington Class Storm", which refers to the geomagnetic storm in 1859, which is still the most powerful after the record.
If again, a hot storm comparable to Carrington, today's technology will be destroyed, the Space Weather Center Boulder, Colorado researchers told National Geographic. Catastrophic damage would include a huge power failure and the destruction of communication networks. In 2017, analysts at the Harvard-Smithsonian Astrophysical Center calculated that the cost of such an event would be the same as the US GDP. Some scientists believe that such extreme solar activity could occur over the next 100 years.
Knipp told Yahoo Finance that scientists could better understand solar activity in the future by studying how the solar storm detonated offshore mines. "What this event does make us aware of what these great storms might look like," Knipp said.
