Descripción
Photopolarimetric observations of the zodiacal light over a complete
solar cycle are used to study the average distribution of brightness and
degree of polarization over the entire sky. It is found that the
brightness ratio between the helioecliptic meridian (the line connecting
the solar and antisolar points) and the ecliptic is independent of
elongation from 35 to 90 deg and that the average isophotes of the whole
high-latitude sky are centered around a point located 15 deg from the
ecliptic towards the antisolar point. The observations also show that
the degree of polarization on the helioecliptic meridian is higher than
that on the ecliptic for elongations greater than 64 deg but lower than
the latter for elongations less than 64 deg. It is concluded that these
results seem to favor an oblate dust cloud, although no model can be
excluded.
