The largest solar storm in five years has engulfed Earth, but scientists say the planet has lucked out so far.

The storm arrived more peacefully Thursday morning than it could
have. Scientists say that could change as the storm spends the day
shaking the planet's magnetic field. It could disrupt technology
but also spread colorful Northern Lights.

The storm started with a massive solar flare earlier in the week
and grew as it raced outward from the sun. The storm arrived at
Earth about 6 a.m. Eastern.

So far officials say there have been no reports of problems with
power grids, GPS, satellites or other technologies that are often
disrupted by solar storms.
