Во время суббуревых активизаций в ходе двух супербурь 2000 и 2003 гг. по данным наблюдений среднеширотных геомагнитных обсерваторий ИСЗФ СО РАН (Монды, Узур) и обсерватории Борок ИФЗ РАН исследуются короткопериодные иррегулярные геомагнитные пульсации, а также свечение ночной атмосферы в эмиссионных линиях кислорода 557.7, 630.0 нм и молекулярной полосе ионизованного азота 391.4 нм (по оптическим данным геофизической обсерватории ИСЗФ СО РАН Торы). С помощью оригинальной техники инверсии магнитограмм ИСЗФ по одноминутным данным мировой сети наземных магнитометров исследуется динамика распределения плотности продольных токов в ионосфере. Показана связь всплесков пульсаций и возмущений в свечении атмосферы в послеполуночном секторе с высыпанием энергичных электронов (~кэВ) и усилением вытекающих продольных токов зоны R2.

Within substorm activations during two superstorms (2000 and 2003) from the observations at mid-latitude geomagnetic observatories, we study short-period irregular geomagnetic pulsations and airglow in the 557.7 nm and 630.0 nm atomic oxygen emission lines, and in the 391.4 nm ionized nitrogen molecular band. Through the genuine magnetogram inversion technique, from the 1-minute data of the ground-based magnetometer global network, we investigate the distribution dynamics for field-aligned currents (FACs) in the ionosphere. The relation is shown between pulsation bursts and airglow disturbances in the post-midnight sector to precipitations of energetic electrons (~keV) and increase in the R2 upward FACs.
