Astronomical refraction above Kufa astronomical observatory

Abstract EN

Astronomical refraction addresses ray-bending effects for objects outside the earth’s atmosphere in relation to an observer within the atmosphere.

In this paper is a study of the Atmospheric refraction and its effect on the light coming from celestial body by using Astronomic Refraction model above Kufa Astronomical Observatory at different zenith angles and different weather conditions.

These weather parameters were collected from the weather link station of the observatory.

The results are perfect agreement with other models.
