On April 12, 1978, something strange happened to the ionosphere above Chatanika, Alaska. Scientists routinely monitoring the flow of ionospheric particles detected very large verticle oscillations corresponding at times to ion velocities of up to 100 meters per second. Normally, ionospheric winds travel almost exclusively in the horizontal direction. And any verticle motions --rarely larger than 2 m/sec -- are usually associated with changes in the magnetic field, but no such va...
