Flare ribbons formed in solar two-ribbon flares after eruptions of prominences diverge in opposite directions from the polarity inversion line of the photospheric longitudinal magnetic field, sharply slowing down with time and distance from this line. Examples of such events are given and the kinematics of flare ribbons is demonstrated. A comparison of the position of the ribbons with the distribution of the photospheric magnetic field shows that the separation of the ribbons slows down when they enter a region of a strong longitudinal field. A simple model of prominence eruption illustrates the kinematic features of the motion of the ribbons and the relation to the sources of the coronal magnetic field in the photosphere.

Вспышечные ленты, образующиеся в солнечных двухленточных вспышках после эрупций протуберанцев, расходятся в противоположные стороны от линии раздела полярностей фотосферного продольного магнитного поля, резко замедляясь со временем и удалением от этой линии. Приведены примеры таких событий и продемонстрирована кинематика вспышечных лент. Сопоставление положения лент с распределением фотосферного магнитного поля показывает, что замедление расхождения лент происходит при их попадании в область сильного продольного поля. Простая модель эрупции протуберанца иллюстрирует кинематические особенности движения лент и связь с источниками коронального магнитного поля в фотосфере.
