The Islamic Crescents Observation Project (ICOP) is an international project founded in 1419 AH (1998 CE), and is maintained by the International Astronomical Center (IAC). ICOP is a group of observers and experts who are interested in astronomical topics related to Islamic applications, such as crescent observation, prayer times, Hejric calendar and Qiblah direction. ICOP members who are located all over the world observe the crescent on a monthly basis and send their observation results, which are published on ICOP website after being verified.
Whereas some ICOP members are interested in crescent observations, other members are experts interested in scientific research and astronomical computations in the related topics. For example, many ICOP members publish papers in the refereed journals and international conferences. In addition, ICOP has very strong relations with official and private societies and associations which are interested in astronomical applications in Islamic topics, such as Islamic ministries, Awqaf departments, Islamic centres and Muslims delegations in Europe and USA. For example, ICOP provides them with calculations of prayer times and crescent visibility.
