The Bruneian Sighting Assembly

On the 29th of each lunar month, observation teams deploy to Bukit Agok, Bukit Shahbandar, and Bukit Ambog. Live transmissions are relayed to the Ministry of Religious Affairs in Bandar Seri Begawan.

The MABIMS Sighting Criteria

Brunei strictly enforces the unified MABIMS criteria (crescent altitude $\ge 3^\circ$, elongation $\ge 6.4^\circ$). Sighting claims below these parameters are reviewed rigorously by the Sharia court.
