The geomagnetic field of the earth shields the earth from the hazards of solar wind which is constantly buffeting the earth making the geomagnetic field assume a comet-like shape. In this paper, interplanetary and geomagnetic data were simultaneously analyzed for the period of the solar cycle 24. The analyses allowed us to determine any teleconnections between the solar wind and geomagnetic activity within the period. Results of the analyses show that solar wind and geomagnetic activity are highly connected at high latitudes but the same cannot be said for mid and low latitudes. Any correspondence between geomagnetic activity indices and solar wind parameters are mere coincidences.

Keywords: Cross-helicity, geomagnetic field, magnetohydrodynamics, residual energy, solar wind, teleconnection
