According to scientists at the University of Bath, the Northern Lights -- or Aurora Borealis -- could be messing with GPS satellite navigation systems. The problem occurs when the satellite signal passes through the phenomena.
Lead scientists Professor Cathryn Mitchell said that, "Anywhere that the aurora is visible, it will cause disruption [to the GPS system]." The Northern Lights are caused when electric charged particles hit the Earth's atmosphere.
Dr Mitchell added: "Although most people in the UK can't see the aurora when it is happening, because of cloud or ambient light, it can still affect the GPS signal. We have just passed a minimum in activity but we are due to hit a maximum in 2012..."
