Al-Musnad: The entry of the Pleiades heralds the beginning of the summer solstice in the Arabian Peninsula.

Arab Weather - Dr. Abdullah Al-Misnad, a former professor of climate science at Qassim University, announced the entry of Thuraya, one of the most prominent lunar mansions of the 28th lunar month, which traditionally marks the beginning of the summer lunar period in the Arabian Peninsula.

The Pleiades are a bright star cluster that can be seen with the naked eye as a cluster of seven prominent stars, while telescopes reveal hundreds of scattered stars that make up this captivating astronomical scene.

Al-Musnad explained that the Pleiades are located astronomically within the constellation of Taurus, and their period of appearance lasts for 13 days. They join Aldebaran and Al-Haq'ah in forming what is known as the "Forty Days of Summer," a period of approximately 40 days characterized by a gradual rise in temperatures and a relative calm in wind movement, compared to previous astronomical phases.
