EL DESARROLLO DE LA ANTÁRTICA Example of the electron auroral budge surrounded by diffuse proton auroralt, belt, photographcd by DAPP satelite in lhe southern poler regíon. (18 58UT. June 24, 1973) rie oxygen atoms excited by the precipitating eleerons. T:he diffused proton aurorae, whieh are mudh {ainter than the eleetron aurorae, are emissi'ons from tJle precipitating protons by reeombining the up– per atmospheric eleetrons. Fig. 11 represents a typical onset of the expansion phase of auroral aetivity (t:he auroral flare). The auroral fIare phenomenon eompri– ses the initial growth phase and the following expansion phase. The growth phase is eommenced by a growth up of the magnetospheric plasma disturbanee eaused by a reeonnection of tíhe magnetospheri~ magnetic fieId with the solar wind magnetic field.
