The sun shines on the Kaaba when it transfers from the Equator to the Tropic of Cancer in May every year.
The sun shined on the Kaaba today, Thursday, May 27, 2021 at 12:18 P.M., Mecca time when the call of prayer for (Dhur) was broadcasted in the Holy Mosque of Mecca.
Today’s sun shine is the first in two this year.
The shadow of the Kaaba and all shadows in Mecca disappear at the moment of the sun shine as the sun is at its zenith ( 89.55 degrees) but the sun slants in the sky of the remote areas according to Eng. Magid Abu Zahera, Head of the Astronomical Society in Jeddah, the Kingdom of Saudi Arabia.
He indicated that ancient people used the sun shine to define the Qibla in a simple way which resembles in its accuracy techniques of modern observation.
Ancient people used to install a piece of wood vertically when the sun shines.
The opposite direction of the shadow goes straight to the honored Kaaba.
Phenomenon of the sun shine also used in measuring circumference of the globe by applying some simple rules in geometryThis method dated back to more than 2000 years and proved the spherical shape of the earth.
The phenomenon occurs because the place of the Kaaba locates between the equator and the Tropic of Cancer.
During the movement of the sun in the sky it becomes at a straight line with the Kaaba during its journey from the Equator to the Tropic of Cancer in May when the first sun shine occurs.
When the sun returns southward from the Tropic of Cancer the second sunshine occurs.
Areas locate under 23.5 degree on the north and south of the Equator see two times the phenomenon of the sun shine in a year but in different times depend on the situation of the place.
Some few places, confined between the Equator, Tropics of Cancer and Capricorn, enjoy the phenomenon of the sun shine.
