They were pretty sure that particles of some sort, driven out of the sun, touch off the northern lights when they hit the earth's atmosphere. But they did not know what the particles were. Dr. Gartlein is sure that they are solar protons hitting the outer fringes of the atmosphere at about 300 miles per second.
