Работа направлена на исследование корреляции между параметрами солнечной активности и геомагнитной активности во время 23-го и 24-го солнечных циклов. Анализ включает такие переменные, как скорость солнечного ветра VSW, плотность протонов Np, динамическое давление солнечного ветра PSW и компоненты межпланетного магнитного поля Bz и By, а также параметры, характеризующие энергию взаимодействия солнечного ветра с магнитосферой ESW, dφ/dt, ε. Были рассчитаны коэффициенты корреляции и временные задержки между перечисленными параметрами и геомагнитными индексами SYM-H, AE отдельно для бурь, вызванных корональными выбросами массы (КВМ), и возмущений, триггером которых являются коротирующие области взаимодействия (КОВ). Анализ временных задержек ∆t авроральной активности относительно энергетических параметров и Bz-компоненты межпланетного магнитного поля для обоих типов бурь выявил запаздывание от 30 до 60 мин, тогда как для кольцевого тока задержки составили от 6 до 24 ч.
