“…These electron events (called "killer" electrons) are not merely a curiosity for scientists, but they can have disruptive consequences for spacecraft [Pilipenko et al, 2006]. While it has been known that there is a general association between geomagnetic storms and electron enhancements [Reeves, 1998], the wide variability of the observed response and the puzzling time delay (∼ 1 − 2 days) between storm main phase and the peak of the response has frustrated the identification of responsible mechanisms and controlling parameters.…”

“…Enhanced reconnection and viscous interaction in dayside boundary regions, leading eventually to substorms, most probably are accompanied by an enhanced level of turbulence. Therefore, substorm break-ups may be preceded by an increased level of ULF power in the region of the dayside boundary layers [Pilipenko et al, 1998]. Also, the pre-heating of the nightside plasmasheet plasma owing to the resonant absorption of MHD turbulence may provide necessary conditions for the onset of an explosive instability, resulting in a substorm break-up (the so called "thermal catastrophe" model of Goertz and Smith [1989]).…”

A ULF wave index, characterizing the level of the geomagnetic field variability in the frequency range 2-7 mHz, has been suggested to the space physics and geophysical community. This global wave index is produced from all available arrays of magnetometers and isolated stations in the Northern hemisphere. A similar ULF wave index is calculated using magnetometer data from geostationary (GOES) and interplanetary (Wind, ACE) satellites. In this review we demonstrate that a wide range of space physics studies, such as the solar wind-ionosphere coupling, wave energy transport, substorm physics, relativistic electron energization, ring current formation, electrodynamics of the ionosphere and magnetosphere, search for electromagnetic precursors of earthquakes, etc., has benefited from the introduction of the provisional ULF wave index. Possible ways of the ULF index advancement and development are discussed. The permanently updating ULF-index database is freely available via the website ulf.gcras.ru for all interested researchers for further validation and statistical studies. KEYWORDS: ULF waves; space weather; substorms; magnetic storms; earthquake precursors; geomagnetically induced currents; discrete mathematical analysis.

Аннотация. В статье дан обзор исследований по динамике релятивистских электронов в области гео-синхронной орбиты. Перечислены физические про-цессы, которые приводят к ускорению электронов, заполняющих внешний радиационный пояс. Являясь одним из факторов космической погоды, потоки высокоэнергичных электронов представляют серь-езную угрозу для функционирования спутниковой аппаратуры в одной из наиболее заселенных орби-тальных областей. Подчеркнута необходимость уси-лий по разработке методов прогноза радиационной обстановки в этой части магнитосферы, перечисле-ны возможные предикторы и дана их классифика-ция. Приведен пример прогностической модели для предсказания потока релятивистских электронов с заблаговременностью 1-2 сут. Обсуждаются неко-торые вопросы практической организации прогнози-рования, перечислены основные задачи краткосроч-ного, среднесрочного и долгосрочного прогнозов.Ключевые слова: радиационные пояса, реляти-вистские электроны, прогноз, магнитосфера, сол-нечный ветер.Abstract. The paper reviews studies of the dynamics of relativistic electrons in the geosynchronous region. It lists the physical processes that lead to the acceleration of electrons filling the outer radiation belt. As one of the space weather factors, high-energy electron fluxes pose a serious threat to the operation of satellite equipment in one of the most populated orbital regions. Necessity is emphasized for efforts to develop methods of forecasting the situation in this part of the magnetosphere, possible predictors are listed, and their classification is given. An example of a predictive model for forecasting relativistic electron flux with a lead time of 1-2 days is proposed. Some questions of practical organization of prediction are discussed; the main objectives of short-term, medium-term, and long-term forecasts are listed.
