Effect on Solar Radiation on Communication

It is important that to stress with space weather deeply concerned earth¿s electromagnetic field always have had continue to have negative effect on health and immune systems of humans and animal. Extreme space weather events follow through Sun , through Solar Corona, inner Heliosphere,Magnetospheric boundary, into the ionosphere and atmosphere, into Lithosphere,and finally, impact on man made structures and activities,such as space craft,G.P.S. signals radio communications and electric power outage.Thus space weather event,have substaintial impact on our technology dependent Society .such solar space weather event ocassionally observed through space weather station in space and ground based observation. Key Wards:- Extreme Space weather Events,Coronal Mass Ejections,Geomagnetic Stroms,Carrington Events ,Human and Technological impact
