A major solar storm is bringing with it an impressive display of the northern lights.

The Aurora Borealis could be seen across northern Scandinavia Tuesday.

"It has been absolutely incredible," British astronomer John Mason cried from the deck of the MS Midnatsol, a cruise ship off coast of northern Norway.

"I saw my first aurora 40 years ago, and this is one of the best," Mason told The Associated Press, his voice nearly drowning in the cheers of awe-struck fellow passengers.

Weather experts say the lights were part of the strongest solar storm in six years.

They predict the sun will continue to get more active in the next few years as a part of its normal cycle.

The radiation from solar storms can effect satellites and cause cell phone systems to drop calls.

U.S. experts from the National Oceanic and Atmospheric Administration said Tuesday evening that so far they haven't heard of any problems from the storm that triggered the auroras.

They said the spectacular lights should be visible for a few more days.
