The largest solar flare in five years is on its way to Earth. Although the solar storm will not be dangerous to humans, it could unleash particles that cause disruption to GPS, airplane flights and power grids. The huge solar flare erupted on Tuesday evening and the wave is expected to hit Earth around 7 a.m. EST on Thursday.

The largest solar storm the Earth has seen since 2005 is currently battering the planet, forcing planes to be re-routed, causing power fluctuations and playing havoc with the Global Positioning System (GPS). The 2012 solar storm currently smacking the Earth is the result of a massive solar flare that erupted from the sun around 11PM EST on Sunday.
