The geomagnetic Kp index is one of the most extensively used indices activity, both for scientific and operational purposes. This article reviews properties provides a reference users associated data products as derived distributed by GFZ German Research Centre Geosciences. near real-time production nowcast particular interest space weather services here we describe evaluate its current setup.

This long-term study examined relationships between solar and magnetic factors and the time course and lags of autonomic nervous system (ANS) responses to changes in solar and geomagnetic activity. Heart rate variability (HRV) was recorded for 72 consecutive hours each week over a five-month period in 16 participants in order to examine ANS responses during normal background environmental perio...

The magnetopause locations as determined by the Explorer 12 SpL charged-particle detector and the Imp I plasma experiment can be used to study the relation between the solar wind parameters and geomagnetic activity. As will be seen, no strong correlation is evident between the size of the magnetosphere, as determined from magnetopause crossings, and geomagnetic activity indexes. It is argued th...

The Earth’s magnetosphere exhibits a complex behavior in response to the solar wind conditions. This behavior, which is described in terms of mutifractional Brownian motions, could be the consequence of the occurrence of dynamical phase transitions. On the other hand, it has been shown that the dynamics of the geomagnetic signals is also characterized by intermittency at the smallest temporal s...

the electrical conductivity of the earth is its physical parameter, which can be studied in global scales. the investigations of the earth's electrical conductivity are based on geomagnetic field variations. time variations of the geomagnetic field consist of long-term and short-term (transient) variations. external sources induce electric currents into the earth. the induced electric curr...
