An evaluation of the chromatic refraction in visual solar observations.
Abstract
An evaluation of the influence of chromatic refraction on visual solar observations is carried out in accordance with the theory by O. A. Melnikov and G. G. Lengauer. For large zenith distances the correction is 0arcsec.4. The chromatic effect "Sun minus star" is shown to reach also 0arcsec.4 for some stars.
