Location signals beamed to Earth by GPS satellites were off by hundreds of feet during the Gannon Solar Storm in May last year, and the disruption lasted for up to two days in some U.S. regions, a new study has revealed. The outage wreaked havoc across the farming sector, which suffered losses of more than $500 million as a result.
A succession of powerful solar eruptions in early May last year triggered the most powerful solar storm to hit Earth in 20 years. Later named after the deceased space weather scientist Jennifer Gannon, the solar storm produced awe-inspiring auroras visible as far south as Mexico, Portugal and Spain. It also made GPS go haywire for days.
