The head of the Astronomical Society in Jeddah, Eng. Majid Abu Zahra, said - in a statement he issued today, Saturday - that the sun at the moment of perpendicularity will be at its maximum zenith of approximately 90 degrees, and the shadow of the Kaaba will completely disappear and the shadows of all objects in Mecca and the shadow of meridian will become zero, while the sun will be tilted in the sky of distant regions in This timing.
He explained that the phenomenon of sun perpendicularity occurs as a result of the location of the Kaaba between the equator and the Tropic of Cancer, so during the apparent movement of the sun across the sky it becomes straight with the Kaaba during its transition from the equator to the Tropic of Cancer during May.
He added that when the sun returns south to the equator coming from the Tropic of Cancer in July.
