The behaviour of H_β emission is examined at the onset and in the course of auroral breakup, on the basis of meridian scanning data of photometers for H_β and green line along with all-sky photographs obtained at Syowa Station, Antarctica in 1971. The result shows that an auroral breakup starts at the poleward boundary of the pre-existing hydrogen arc, that a global breakup frequently starts when an electron auroral arc comes into contact with the pre-existing hydrogen arc, that the enhancement of H_β takes place in the region bounded by the westward travelling surge, the poleward shifting arc and the pre-existing hydrogen arc with a spatial negative correlation between electron aurora and hydrogen emission, and that the behaviour of a local breakup is substantially similar to that of a global breakup though it has no "contact" of electron aurora.
