   <abstract xml:lang="ru">
    <p>Исследованы экстремальные состояния глобальной возмущенности магнитосферы: очень спокойное и сильно возмущенное — и их связь с параметрами межпланетной среды. Оценка степени глобальной возмущенности магнитосферы проводилась по месячному и годовому количеству магнитно-спокойных и магнитно-возмущенных дней. Выполнено сравнение циклических и сезонных распределений количества магнитно-спокойных и магнитно-возмущенных дней и проанализирована их связь с параметрами межпланетной среды с 20-го по 24-й циклы солнечной активности. Показано, что максимальное число магнитно-спокойных дней наблюдается на фазе подъема солнечной активности и в сезон зимнего солнцестояния, а максимальное число магнитно-возмущенных дней — на фазе спада солнечного цикла и в сезон равноденствий. Обнаружено аномальное возрастание числа спокойных дней в 24-м цикле солнечной активности по сравнению с предыдущими циклами. Установлено, что циклическая вариация годового числа спокойных и возмущенных дней определяется поведением и величиной скорости, температуры, динамического давления плазмы солнечного ветра и модулем напряженности межпланетного магнитного поля. Предполагается, что обнаруженный всплеск числа спокойных дней в фазу подъема 24-м солнечного цикла отражает внутренние процессы на Солнце и связанные с ними изменения параметров межпланетной среды. Закономерности циклической и сезонной вариации числа магнитно-спокойных и магнитно-возмущенных дней и их связь с параметрами солнечного ветра могут быть использованы для прогноза космической погоды.</p>

    <p>This paper deals with extreme conditions of the global magnetosphere disturbance: very quiet and greatly disturbed, and their relationship with interplanetary medium parameters. The degree of global magnetosphere disturbance was estimated from the monthly and annual number of magnetically quiet and magnetically disturbed days. The cyclic and seasonal distributions of magnetically quiet and disturbed days were compared, and their relationship with interplanetary medium parameters in solar cycles 20–24 was analyzed. Magnetically quiet days are shown to be mainly observed at the ascending phase of solar activity and during the winter solstice season. Magnetically disturbed days dominate at the descending phase of the solar cycle and during the equinox season. An anomalously large increase in the number of quiet days was found in solar cycle 24 as compared to previous cycles. It has been established that the cyclic variation in the annual number of quiet and disturbed days is determined by the behavior and magnitude of the speed, temperature, dynamic pressure of solar wind plasma and the interplanetary magnetic field modulus. The detected burst in the number of quiet days during the ascending phase of solar cycle 24 is assumed to reflect internal processes on the Sun and related changes in interplanetary medium parameters. The patterns of cyclical and seasonal variation in the number of magnetically quiet and disturbed days and their relationship with the solar wind parameters can be used to predict space weather.</p>
