“…Recently Wilcox et al (1969) have reported a correlation of the daily mean magnetic field of the sun (seen as a star) with the polarity of the interplanetary magnetic field observed 4k days later near the earth for the interval March-June 1968. They report an almist complete agreement.…”

“…The smallest density structures are at least two orders of magnitude smaller than those observed in white-light measurements, but are comparable to the smallest magnetic scales deduced indirectly from photospheric field measurements (13). While the presence of open magnetic fields in the quiet Sun appears to contradict the long held view that they are restricted to coronal holes, it is necessary to understand that coronal magnetic fields have not been measured directly, and that the traditional view is based solely on the impression of diverging polar coronal holes from white-light pictures, and theoretical magnetic field modeling only of large-scale structures (14,15). Recent high spatial resolution eclipse measurements reproduced in Figure 5 (16) suggest that open field lines do indeed emerge from the quiet Sun.…”

“…При этом для сложных моделей второго подхода в качестве начальных условий применяют-ся упрощенные модели, разработанные для задач первого подхода. Наиболее распространенным под-ходом первого уровня являются расчеты в рамках модели поверхности источника в приближении по-тенциального поля (Potential Field Source Surface, PFSS) [Schatten et al, 1969;Altschuller, Newkirk, 1969;Hoeksema, 1984;. В такой модели предполагается, что магнит-ное поле в короне потенциальное (такое вынужден-ное упрощение означает игнорирование токов в фо-тосфере и хромосфере, которые в действительности, конечно же, присутствуют, и пренебрежение сила-ми, связанными с газовым давлением) и становится абсолютно радиальным, начиная с некоторого уровня над фотосферой.…”
