Citizen – Mohammed Daoud – Jeddah
The Astronomical Society in Jeddah announced that the crescent of the month of Dhul Qi’dah will be observed after sunset tomorrow, Friday, June 11, 2021, and move towards the beginning of the night, where it is seen with the naked eye on the western horizon in the sky of the Arab world, which is an ideal opportunity for astronomical photography.
Seeing the new crescent:
The head of the Astronomical Society in Jeddah, Eng. Majed Abu Zahira, explained that the moon will be away from the glare of sunset sunlight compared to the previous day, and it will become high in the sky, which is another position of the moon’s houses called “the crescent” and means seeing the new crescent after its association with the sun and its exit from the position of the moon. , and far enough distance from the sun for the emergence of light on its surface.
Glow in dim light:
He added, the observer with the naked eye will notice, within a few nights, that the unlit side of the moon’s surface with sunlight glows with a dim light, which is sunlight reflected from the Earth and falling on the moon, in a phenomenon referred to as the new moon embracing the old moon.
first square phase:
He pointed out that the moon reached the position of conjugation on Thursday 29 Shawwal 1442 corresponding to June 10, 2021 at 01:52 pm (10:52 am GMT), moving from the west of the sun to its east in conjunction with an annular eclipse of the sun that was not seen in the Arab world, as that by observing the moon day after day, he will notice that its illumination increases and rises high in the sky at sunset, and remains longer after the beginning of the night; This is because the moon is moving away from the location of the sunset towards the east through the sky, which is its natural movement in orbit around the earth, and after seven days of conjugation, the moon will reach the first square phase.
The real motion of the moon:
Abu Zahira concluded by saying, the reason is that we see the moon moving towards the west every day as a result of the earth’s rotation on its axis, but the real movement of the moon is towards the east with respect to the stars and planets in the zodiac circle while it revolves around the earth, and this time of the lunar month is ideal for observing Faint objects in the depths of space such as galaxies, nebulae, and star clusters come from locations outside cities because the sky will be dark after the moon sets early, which usually obliterates the natural lights in the sky’s dome.
