Some Comments on the Auroral-Electro jet Formation (Reports of the Japanese Antarctic Research Expedition)
The essence of the auroral-electrojet is an association with the rapid motion of the aurora. We estimate the three-dimensional current distribution based upon the change of 4278 Å line aurora observed at Syowa Station by HIRASAWA (1971). The auroral luminosity change (the local change plus the chang...
