Sažetak

This article presents the nature of the Sun’s and Earth’s magnetic fields, their mutual connection and anomalies. The number of sunspots, that increase and decrease in unequal cycles, correspond to the number of registered magnetic storms on the Earth. The Sun’s plasma streams that shoot out from the sunspots cause an increase in the solar winds and in doing so they affect the geomagnetic field and the Earth’s atmosphere. One example of such a causal connection was the most extreme magnetic storm that has occurred during the last two Sun Cycles. It lasted from October 28th to November 2nd 2003. Successful navigation depends on taking into consideration all the changes on the Earth that arises from changes on the Sun.
