THE TERRESTRIAL RESPONSE OF THE SOLAR CYCLES NO. 21, AND 22

摘要

Solar emissions effected the geomagnetic Processes are investigated for 21st and 22nd. They have produced a higher level of sunspot, and flare activity than previous cycles. Each of them have a different response on theEarth environment This may be attributed to the variance in the emission types, and in the energetic particles ejected by its solar magnetic configurations. Coronal Mass Ejections (CMEs) play a major role in accelerating, and enlargement proton flux. The filament disappearance shows an incomparable active level between solar cycles 21 and 22, i.e., a very large proton flux CMEs was observed during the 22nd cycle in contrast to that detected during solar cycle No. 21, which was characterized by a rich production of electron dominated flare enhancements. The geommagnetic index A_(p~-) index is well proportional to the number of proton events enhanced from the two cycles.
