   <abstract xml:lang="ru">
    <p>Предложена методика оценки средней энергии потока высыпающихся электронов по измерению интенсивности эмиссии λ427.8 нм. В основу методики положены экспериментальная зависимость отношения интенсивностей эмиссий λ630.0 и λ427.8 нм от интенсивности эмиссии λ427.8 нм и результаты модельных расчетов зависимости средней энергии потока авроральных электронов от I₆₃₀.₀/I₄₂₇.₈. Приведены численные оценки влияния на данную зависимость трех факторов: формы энергетического спектра авроральных электронов, содержания атомарного кислорода нейтральной атмосферы и концентрации окиси азота NO. Рассчитана зависимость средней энергии потока авроральных электронов от интенсивности эмиссии λ427.8 нм, и представлена ее аналитическая аппроксимация.</p>

    <p>We propose a method for estimating average energy of precipitating electrons from 427.8 nm emission intensity measurements. This method is based on the experimental dependence of the ratio of λ630.0 and λ427.8 nm emission intensities on the λ427.8 emission intensity and model calculations of the dependence of the average auroral electron energy on the I₆₃₀.₀/I₄₂₇.₈ ratio. We present numerical estimates of the influence of three factors on this dependence: the shape of the auroral electron energy spectrum, the atomic oxygen concentration, and the NO concentration. The dependence of the average energy of the auroral electron flux on the 427.8 nm emission intensity is obtained and its analytical approximation is presented.</p>
