   <abstract xml:lang="ru">
    <p>По данным измерений на спутниках ИНТЕРБОЛ-1 и МАГИОН-5 проекта ИНТЕРБОЛ в 1995 -2001 гг. проанализирована зависимость характеристик экваториальной плазмосферы от местного магнитного времени, а также от солнечной активности, динамического давления и плотности солнечного ветра. Плотность протонов в годы минимума солнечного цикла в среднем выше, чем в годы максимума, что, вероятно, является следствием изменения массового состава плазмы в плазмосфере. Дневные и ночные температуры протонов возрастают с увеличением потока ультрафиолетового излучения Солнца, по крайней мере, в годы максимума солнечного цикла. Плотность и тепловое давление плазмосферной плазмы увеличиваются с ростом динамического давления и/или плотности невозмущенного солнечного ветра, что, возможно, связано с перестройкой электрического поля конвекции в магнитосфере.</p>

    <p>Measurements from the Interball-1 and Magion-5 satellites of the Interball mission in 1995–2001 have been used to analyze the dependence of the equatorial plasmasphere characteristics on magnetic local time, as well as on solar activity, dynamic pressure, and solar wind density. The proton density at solar minimum is on average higher than at solar maximum, which is probably due to changes in plasma mass composition in the plasmasphere at solar maximum. The daytime and nighttime proton temperatures increase with increasing solar extreme ultraviolet flux, at least in the years of solar maximum. The plasmaspheric plasma density and thermal pressure rise with increasing dynamic pressure and/or density of the undisturbed solar wind, which might be associated with restructuring of the convective electric field in the magnetosphere.</p>
