    <p>Исследованы питч-угловая анизотропия и дифференциальные жесткостные спектры космических лучей во время наземных возрастаний 2 и 6 мая 1998 г. методом спектрографической глобальной съемки на основе данных наземных измерений космических лучей на мировой сети станций нейтронных мониторов (39 нейтронных мониторов). Получены дифференциальные жесткостные спектры солнечных космических лучей в исследуемые периоды. Определены максимальные жесткости, до которых произошло ускорение протонов в этих событиях. Максимальная жесткость ускоренных частиц во время наземного возрастания 2 мая составила ~2.4, 6 мая — ~1.8 ГВ. Обнаруженная двунаправленная анизотропия свидетельствует о нахождении Земли в петлеобразной структуре ММП типа магнитной ловушки и в первом, и во втором событиях.</p>

    <p>Using data from the worldwide network of neutron monitors (39 stations) and the method of global spectrographic survey, we have studied pitch-angle anisotropy and differential rigidity spectra of cosmic rays during the ground level enhancements on May 2 and 6, 1998. We obtained differential rigidity spectra of solar cosmic rays in these events and determined the maximum rigidities to which protons accelerated. The maximum rigidities of accelerated protons during the ground level enhancements on May 2 was ~2.4; on May 6, ~1.8 GV. The revealed bidirectional pitch-angle anisotropy indicates that Earth was in the IMF loop structure during these events.</p>
