An evaluation of the subsolar pressure balance between the solar wind and the geomagnetic field shows that the average proton density of the quiet-day solar wind (300-400 km/sec) should be between 6 and 10 p/cm a. Even during storm times the proton density should always be between 2 p/cm 3 and 70 p/cm 3. The relation between the interplanetary solar-wind parameters and the stagnation pressure i...
The idea of two separate storm time ring currents, a symmetric and an asymmetric one has accepted since the 1960s. The existence of a symmetric equatorial ring current was concluded from Dst. However, the asymmetric development of the low-latitude geomagnetic disturbance ®eld during storms lead to the assumption of the real existence of an asymmetric ring current. I think it is time to inquire ...
The Auroral Electrojet (AE) indices, which are composed of four indices (AU, AL, AE, and AO), are calculated from the geomagnetic field data obtained at 12 geomagnetic observatories that are located in geomagnetic latitude (GMLAT) of 61.7–70. The indices have been widely used to study magnetic activity in the auroral zone. In the present study, we examine magnetic local time (MLT) dependence of...
