The first quarter of the Shawwal moon was observed in the northern borders

In a spectacular astronomical display that captivated enthusiasts and amateur astrophotographers, the first quarter moon of Shawwal 1447 AH was observed in the skies of the Northern Borders region on Wednesday evening. This phenomenon is considered one of the most beautiful monthly astronomical events, offering observers an exceptional opportunity to contemplate the details of the moon's surface with perfect clarity, whether with the naked eye or through the use of telescopes and advanced astronomical instruments.

What is the first square phase?

The first quarter phase is one of the key and important phases in the lunar cycle. During this phase, half of the moon is fully illuminated by sunlight, while the other half remains in darkness. This occurs because the moon is positioned at an almost right angle (90 degrees) between the Earth and the sun. This precise geometric position makes the moon stand out and appear high in the sky at the beginning of the night, representing an important transitional phase as the illuminated portion gradually increases day by day until the full moon phase.

The importance of moon observation in Islamic culture and history

Observing the phases of the moon holds immense historical and cultural significance, particularly in the Islamic world. The Islamic calendar (Hijri calendar) relies entirely on the moon's movement and phases to determine the beginnings and ends of the lunar months. The month of Shawwal holds a special place as its beginning coincides with Eid al-Fitr. Historically, Arabs and Muslims excelled in astronomy, using observatories to track the movement of celestial bodies. This contributed to the development of mathematics and maritime navigation, which depend on the positions of stars and the phases of the moon to determine directions and tides.

Local and regional impact: Astronomy tourism in Saudi Arabia

Locally, the Northern Borders region stands out as one of the most distinctive geographical areas in Saudi Arabia, boasting clear skies for much of the year and minimal light pollution across its vast expanse. This makes it an ideal destination for astronomy enthusiasts and astrotourism. Observing the first quarter of the Shawwal moon enhances scientific awareness among youth and the local community, and encourages the organization of astronomical events that attract visitors from within the Kingdom and abroad, aligning with the goals of Saudi Vision 2030 to diversify tourism sources and support scientific and cultural activities.

Why do astronomers prefer the first quarter phase?

From a scientific and technical standpoint, astronomers and amateur astrophotographers agree that the first quarter phase is the best time to observe and photograph the Moon's topography. This is due to the Terminator, the line separating the illuminated and dark sides of the lunar surface. In this region, the sun's rays strike the Moon at a very oblique angle, casting long, distinct shadows on impact craters, lunar mountains, and valleys. This dramatic contrast in light highlights topographical details in a way that is impossible to see during the full moon, when the sun's rays are directly overhead and shadows disappear completely.

In conclusion, observing the first quarter of the Shawwal moon in the skies of the northern borders remains a reminder of the beauty and precision of the cosmic order, an open invitation to contemplate God’s creation, and a continuous scientific opportunity to promote astronomical knowledge in society.
