The light rays from the sun are refracted by the atmosphere. The closer the sun is to the horizon, the more this refraction is. Consider the sun when its lower edge appears to be on the horizon. Were it not for the refraction, the sun would just then actually have its lower edge a little more than half a degree below the horizon. The upper edge, in the meantime, appears to be slightly less than half a degree from where it would be if there were no refraction. As a result, the vertical width of the sun appears to be somewhat less than it would be with the sun overhead. The horizontal width suffers very little shortening due to refraction. Thus, when the sun is on the horizon, it appears to be an ellipse.
