The results obtained in the observation can be summarized as follows. (1) We performed the first vector observation in the middle latitude. (2) The ionospheric current is very weak except from 102 km to 115 km height at 11 : 00 LT. (3) There is some posibility of the existence of a weak subsidiary current layer at about 130 km and 150 km. (4) The horizontal current is especially weak in the height range of 82-100 km and 135-150 km, and current density is less than 0.1 Amp/km^2. (5) These observational results shows that the thickness of the main current layer is about a half of the value estimated from the distributions of the ionospheric conductivity and wind system., 資料番号: SA0166518000}, pages = {3--11}, title = {S-310-5 号機による電離層電流系の観測 (II)}, volume = {2}, year = {1982} }
