“…Since the concept of solar atmosphere extension and expansion into interplanetary space [18] endorsed by Pioneer V [19], showed to contain loopholes [20], and Magnetosphere breached continually by solar wind in several places [21], it is suggested that, both the flow of energetic protons [22], and energetic electrons >200 keV [23], in Magnetosheath, and the concentration of high density solar wind positive ion ranging between 35 to 127 cm -3 at Magnetosheath [22], contrary to background proton's density of 5-10 cm -3 [24], and Magnetosheath plasma interaction with magnetosphere at magnetopause, which results in fluctuations and strong magnetic fields, leading to an intense geomagnetic storm Dst<200 n Tesla [25], a situation which is similar to the ionospheric elongated diamagnetic cavity created after High-altitude Nuclear Detonation (HND) [1], therefore it is suggested that, both MS and HND are similar in nature, and resulted from charged particles interaction with geomagnetic field.…”
