Comisión Islámica de España and State Partnership

The Comisión Islámica de España (CIE), established under the historic 1992 Cooperation Agreement between Spain and Islamic communities, acts as the official liaison between Spanish Muslims and the government. CIE coordinates moon sighting observations from northern Spain through Andalusia and the Ceuta and Melilla enclaves on the African coast.

Crescent Observation and Mediterranean Horizon Standards

On the 29th of each lunar month, CIE-affiliated scholars and observers scan the Mediterranean and Atlantic horizons from Madrid, Seville, Granada, Valencia, and the autonomous cities of Ceuta and Melilla. The geographic diversity of Spain, including the Canary Islands, means observation data is collected from multiple time zones and horizons.
