Introduction
Because the sun is composed of gases that are constantly
reacting, there is a lot of activity there. At various times there
are solar events such as solar flares, coronal holes, solar winds,
and others.
These activities cause geomagnetic storms that can
affect many things here on Earth. The Northern and Southern Lights
occur because of sun activities. Radio transmission, satellite reception,
and airplane communications are just a few of the problems the sun
can cause.
Geomagnetic storms occur in patterns and can sometimes
be predicted. Knowing about the storms and their effects can help
us in many ways worldwide.
