   <abstract xml:lang="ru">
    <p>Эволюция магнитного поля в фотосфере на ранней стадии развития активной области изучалась по данным о продольной компоненте магнитного поля и лучевых скоростях, полученным   с помощью SOHO/MDI и SDO/HMI. Визуальная инспекция 48 случаев возникновения активных областей и детальный анализ динамики потоков магнитного поля четырех активных областей показали, что в момент выхода нового магнитного поля первым в фотосфере обнаруживается поле последующей полярности. Асимметрия потоков лидирующей и последующей полярностей сохраняется несколько десятков минут. Наблюдаемая асимметрия магнитных потоков подтверждает результаты численного моделирования выхода магнитного поля активной области в верхних слоях конвективной зоны, выполненного Ремпелем и Ченгом [Rempel, Cheung, 2014].</p>

    <p>We study the evolution of the photospheric magnetic field at the early stage of active region development. We use data on longitudinal component of the magnetic field and line-of-sight velocities from SOHO/MDI and SDO/HMI. The visual inspection of 48 cases of birth of active regions and the detailed analysis of the magnetic flux dynamics in 4 active regions have shown that at the time of emergence of a new magnetic field, the field of the following polarity is the first to be detected in the photosphere. The flux asymmetry of the leading and following polarities persists for several tens of minutes. The observed asymmetry of magnetic fluxes supports the results of the numerical simulation of emergence of the active region magnetic field in the upper layers of the convective zone, which has been carried out by Rempel and Cheung [2014].</p>
