The geomagnetic severe storm on November 7-11, 2004 had Dst=-383 nT and had probably caused by the coronal mass ejection (CME) in interplanetary space. The burst of solar X-ray preceded the halo-ejection of solar plasma. The experimental fact testifying the global response of the geomagnetic field ("crochet" type) observed after the solar flare on November 6, 2004 is given. The reaction in the geomagnetic field lasted for several hours as well as X-ray bursts registered aboard GEOS-12.

Based on the data of longitudinal chain of midlatitude stations in the northern hemisphere, substorm-associated field-alighned currents (FACs) are examined. A comparison of IMF component variations with surface FAC characteristics in substorm sites is performed. It is shown that the ratio between the upward and downward surface FAC intensities depends on By IMF. In this regard, the conditions are discussed that favor currents flowing from the dayside cusp to nightside auroral region. These currents, which position is dependent on By IMF direction, can be responsible for difference between the upward and downward current-wedge-associated FACs.
