Astronomy: Rabia al-Awwal crescent birth to coincide with solar eclipse

Astronomers anticipate a unique celestial event in August 2026, as the astronomical birth of the new moon crescent marking the Islamic month of Rabia al-Awwal will coincide with a solar eclipse. This conjunction, calculated to occur on August 12, 2026, at 18:37 local Tunisian time, will present as a total solar eclipse.

For Tunisia, the eclipse will be visible as a partial phenomenon. Astronomical data suggests the first opportunities to observe the Rabia al-Awwal crescent will be on August 13, starting from 8:58 local time, particularly in regions west of the Pacific Ocean and central Australia. Visibility is expected to expand westward as astronomical conditions evolve.

The significance of this event lies in the rare alignment of the new moon's birth with a solar eclipse, a phenomenon of considerable astronomical interest. However, the article emphasizes that while astronomical calculations can determine the new moon's birth and crescent visibility conditions, the official declaration of the lunar month's start in Tunisia rests solely with the Diwan of Ifta.
