Do not miss … the moon’s first perpendicular to the Holy Kaaba in a phenomenon that can be seen with the naked eye

Today, Thursday, Jumada Al-Akhira 15, 1442, corresponding to January 28, the sky of Makkah Al-Mukarramah will witness the perpendicularity of the moon to the Holy Kaaba in conjunction with its occurrence in the full moon phase, which is the first orthodoxy this year 2021.

The moon will rise with sunset from the north-north-eastern horizon and set on the north-northwest horizon, which means that it will simulate the high path of the summer sun after six months across the night sky, while the north of the Arctic Circle remains the moon 24 hours above the horizon, like the midnight sun in the summer.

In the southern hemisphere, the full moon follows the low path of the winter sun, where the moon is low in the sky, just like the winter noon sun, and in the south of the Antarctic Circle the moon remains below the horizon for 24 hours.

The moon will reach the moment of the full moon at an angle of 180 degrees from the sun at 07:16 PM GMT, thus completing half of its orbit around the earth during this month .

This will be followed by the arrival of the moon at the moment of perpendicularity at (09:43:34 pm GMT) and it will be at an altitude (89.57.46 degrees) and its disk is fully illuminated by (99.9%) and at a distance of 381.125 km, and after perpendicularity the moon will remain visible in the sky for the rest of the night until To set at sunrise on Friday .

The phenomenon of perpendicularity is one of the scientific methods to confirm the accuracy of calculations of the movement of celestial bodies, including the moon, which makes determining its position very accurate in addition to that this astronomical phenomenon can be used to know the direction of the qiblah in a simple way from several regions around the world as the ancients did .

Residents of geographical locations far from the Grand Mosque and where the moon is seen above the horizon at the moment of perpendicularity, the direction of the moon points to Mecca in a manner comparable to the accuracy of smart phone applications .

In general, the middle of the lunar month is considered the ideal time for observing the radioactive craters on the surface of the moon through binoculars or a small telescope, unlike the rest of the terrain that appears flat due to the fall of the entire moon in the sunlight, these radiating craters are deposits of bright reflective materials that extend from the center of the craters outwards for hundreds Kilometers, and these craters are believed to be newly formed.

During the coming nights, the moon will rise about an hour late every day, and within a few days it will be seen only in the sky of dawn and early morning, and at that time it will reach the final square stage a week after it has fallen into the full moon stage.
