Solar storm blasts aurora borealis light shows (Videos, images) The largest solar flares since 2005 blasted past Earth on Tuesday. Despite warnings from space experts of possible interference to GPS signals, the solar storm turned out to be a mild 2 on a scale of 1 to 5. Even so, it created some spectacular aurora borealis the past few nights. See images and videos of the lights dancing over the Northern Hemisphere below: Near the city of Tromsoe, northern Norway.
