70TH ANNIVERSARY OF THE 1956 GROUND LEVEL EVENT: It doesn’t have a catchy name, and most people have never heard of it. Yet space scientist Clive Dyer of the Surrey Space Centre can’t stop worrying about ‘GLE05’–a major solar radiation storm in 1956.
“Today is the 70th anniversary of that extreme space weather event,” says Dyer. “If it happened again today, it would have a significant impact on air travel and modern technology.”
