   <abstract xml:lang="ru">
    <p>В работе рассматриваются изменения среднесуточных значений индексов Dst, SYM-Н, ASY-Н и ASY-D и их зависимость от уровня магнитной возмущенности за период 1981–2016 гг. Эти индексы являются геомагнитными характеристиками магнитосферного кольцевого тока. Установлено, что индексы асимметричной компоненты кольцевого тока АSY-H и АSY-D в относительно магнитно-спокойные периоды не равны нулю. Определены смещения значений в зависимостях индексов ASY-Н и ASY-D от уровня магнитной возмущенности. Анализируется поведение показателя степени симметрии кольцевого тока — отношения SYM-H/ASY-H — в течение года при разных уровнях возмущенности. Обнаружено, что это отношение растет по абсолютной величине по мере возрастания возмущенности и при больших возмущениях (при Dst&lt;–50) превышает 1.</p>

    <p>The paper considers changes in the daily average values of the Dst, SYM-H, ASY-H, and ASY-D indices and their dependence on the level of magnetic disturbance for the period 1981–2016. These indices are geomagnetic characteristics of the magnetospheric ring current. It has been established that the indices of the asymmetric component of the ring current ASY-H and ASY-D during relatively magnetically quiet periods are not equal to zero. The values of the offsets in the dependences of the ASY-H and ASY-D indices on the level of magnetic disturbance have been determined. The behavior of the index of the degree of symmetry of the ring current, the ratio SYM-H / ASY-H, is analyzed during the year at different levels of disturbance. This ratio has been found to grow in absolute value with increasing disturbance and to exceed 1 at large disturbances (at Dst &lt;–50).</p>
