   <abstract xml:lang="ru">
    <p>С помощью модернизированной техники инверсии магнитограмм продолжено изучение физических процессов в ходе магнитосферной бури 17.08.2001 на основе анализа динамики интенсивностей продольных токов (ПТ) в зоне 1 Ииджимы—Потемры в полярных ионосферах двух полушарий Земли. Полученные результаты о динамике асимметрии ПТ двух типов (утро–вечер и межполушарной), как и полученные нами ранее закономерности поведения токов Холла и границ полярных шапок в зависимости от наблюдавшейся в ходе бури большой азимутальной компоненты межпланетного магнитного поля (ММП) и сезонного хода проводимости, соответствуют открытой модели магнитосферы и результатам спутниковых наблюдений полярных сияний в двух полушариях. Показано, что ослабление асимметрии двух типов в распределении ПТ во время суббурь, имевших место в ходе исследуемой бури, происходит практически полностью в зимнем полушарии и значительно слабее — в летнем. Это явление мы связываем с преобладанием эффекта длительного воздействия азимутальной компоненты ММП в освещенной полярной ионосфере летнего полушария над суббуревым эффектом симметризации ночной магнитосферы. Отмечен эффект симметризации полярной шапки и ПТ, создаваемый импульсом давления солнечного ветра в конце бури, предложено качественное объяснение этого эффекта.</p>

    <p>We continue to study the physical processes occurring during the August 17, 2001 magnetospheric storm by analyzing the dynamics of the intensity of field-aligned currents (FACs) in Iijima—Potemra Region 1 in the polar ionospheres of the two hemispheres, using the modernized magnetogram inversion technique. The results obtained on the dynamics of two types of FAC asymmetry (dawn-dusk and interhemispheric), as well as the previously obtained regularities in the behavior of Hall currents and the polar cap boundaries depending on the large azimuthal component of the interplanetary magnetic field (IMF), observed during the storm, and the seasonal behavior of the conductivity are consistent with the open magnetosphere model and with satellite observations of auroras in two hemispheres. We have shown that the weakening of the asymmetry of two types in the FAC distribution during substorms in the storm under study occurs almost completely in the winter hemisphere and is much weaker in the summer one. We associate this phenomenon with the predominance of the effect of long-term exposure to the azimuthal IMF component in the sunlit polar ionosphere of the summer hemisphere over the substorm symmetrization effect of the night magnetosphere. A symmetrization effect of the polar cap and FACs, created by the solar wind pressure pulse at the end of the storm, is observed. We propose a qualitative explanation of this effect.</p>
