May 27, 2025 / 9:50 PM

Sharjah24: Amar Issa Abdullah, Director of the Astronomical Observatories Department at the Sharjah Academy of Astronomy, Space Sciences & Technology, announced that the Sharjah Astronomical Observatory began the observation of the Dhul-Hijjah crescent for the year 1446 AH on Tuesday at its location in the University City. This effort is in collaboration with the Crescent Moon Sighting Committee of the UAE Council for Fatwa, utilising advanced telescopes and observational equipment to measure the crescent’s thickness, elongation, and age, preparing to submit the results for official confirmation.

Crescent moon sighting process

Amar Issa confirmed that the observatory commenced its crescent moon sighting activities after sunset on Tuesday, the 29th of Dhul-Qi'dah, as part of its second meeting for this year.

In an exclusive statement to "Sharjah 24," Amar explained that the observation utilises a range of advanced astronomical devices, primarily the high-precision refracting telescope, along with CCD sensors and automated tracking systems that allow for precise recording of astronomical images and data.

Compliance with established standards

The Director of the Astronomical Observatories indicated that the observatory team operates according to the approved standards for crescent moon sighting in the UAE. This includes calculating the crescent's thickness after sunset, its angular elongation, and its age since conjunction, in addition to assessing atmospheric clarity and background sky illumination. These parameters are continuously monitored using specialised astronomical software to ensure accurate results.

Submission of results

Amar added that all images and measurements are immediately submitted to the Crescent Moon Sighting Committee of the UAE Fatwa Council. The committee studies the field reports and astronomical calculations before announcing the visibility of the crescent, paving the way for the official decision regarding the first day of Dhul-Hijjah.
