CALCULATION OF THE GLOBAL SYSTEM OF THE FIELD-ALIGNED CURRENTS ON THEDAYSIDE OF THE MAGNETOSPHERE

Using the well-known equation for the normal component of the current which exist near the tangential discontinuity in the plasma in the cas e of the frozen-in magnetic field, and supposing that the current clos es in the ionosphere in the auroral oval in the region 1, one calculat es and compares with the data of observations the dependence of the de nsity of the field-aligned current at the level of the ionosphere on t he local time.
