   <abstract xml:lang="ru">
    <p>Рассмотрена солнечная вспышка X9.3, произошедшая 6 сентября 2017 года. Изучение вариаций свойств мелкомасштабных флуктуаций плотности вероятности потоков солнечного рентгеновского излучения с космического аппарата GEOS позволило выделить набор повторяющихся перед вспышкой событий. За 20—70 часов до вспышки предшествует серия от 1 до 8 предвестников.</p>

    <p>The X9.3 solar flare that occurred on September 6, 2017 is considered. The study of variations in the properties of small-scale fluctuations in the probability density of solar X-ray fluxes from the GEOS spacecraft made it possible to identify a set of events that repeat before the flare. A series of 1 to 8 precursors precedes the outbreak 20–70 hours before.</p>
