Abstract
The extensive fields of force shown by the spectroheliograph in the hydrogen atmosphere surrounding sun-spots have been explained in two different ways: (1) as true hydrodynamical vortices, resembling great tornadoes, and (2) as electromagnetic phenomena, in which charged particles moving in the solar atmosphere are constrained by the magnetic fields in the spots to follow their lines of force. The principles involved in the electromagnetic theory have been applied to the explanation of the terrestrial aurora by Stormer, who has also developed this theory for the case of sun-spots.(1)
