   <abstract xml:lang="ru">
    <p>Проведен анализ процесса переноса от Солнца до Земли энергичных протонов, ускоренных в солнечных вспышках. Используется модель, в которой предполагается, протоны движутся к Земле в электромагнитном поле паркеровского представления. В рамках этой модели показано, что регистрация протонов на Земле происходит в том случае, когда протоны, движущиеся от вспышечной области Солнца, попадают в окрестность гелиосферного токового слоя, а Земля находится от нейтральной линии токового слоя на расстоянии, меньшем ларморовского радиуса протонов. Представлен анализ экспериментальных данных о солнечных вспышках в августе–сентябре 2011 г., из которого следует, что отсутствие регистрации энергичных протонов в окрестности Земли для некоторых мощных солнечных вспышек находит объяснение в рамках предложенной модели.</p>

    <p>We analyze the Sun-to-Earth transport of energetic protons accelerated in solar flares. We use a model which assumes that protons move earthward in the Parker electromagnetic field. In this model, protons are shown to be recorded on Earth when they, moving away from the solar flare region, reach the vicinity of the heliospheric current sheet, while Earth is at a distance smaller than the proton Larmor radius from the current sheet neutral line. We present the analysis of experimental data on solar flares in August–September 2011. This analysis shows that the absence of energetic protons recording in the vicinity of Earth for some major solar flares can be explained by the proposed model.</p>
