Aurorae For centuries, observers in northern Europe reported colorful dancing lights in the night sky toward the north, and as man colonized other continents similar reports came from Canada and Alaska, as well as southern portions of Australia. We now know that these "dancing lights" are caused when high-energy particles from the sun slam into Earth's magnetic field. The proper name for these lights is the Aurora Borealis in the Northern Hemisphere and the Aurora Australis in the Southern Hemisphere. In rare instances, when solar activity is high, aurorae can be seen from the mid-latitudes of the northern and southern hemisphere. The following images represent some of the best from members of the River Bend Astronomy Club.
