Abstract
The paper presents measurements of the absolute surface brightness at three wavelengths, the polarization at two wavelengths and the position of the zodiacal light made from the high altitude station of Chacaltaya in the Bolivian Andes (height 17 100 ft, geomagnetic latitude 3° S). This site is particularly suited to such observations because the weather is good and the atmospheric extinction is close to that expected for a dust-free Rayleigh scattering atmosphere. The brightness and polarization measures extend to within 19° of the Sun. The colour is close to that of the Sun, but it is slightly more red; the polarization measures agree well with those recently obtained by Elsässer.Keywords
