Recommendations of the Conference

Under the patronage of His Highness Sheikh Mansour Bin Zayed Al Nahyan, minister of presidential affairs, the Emirates Astronomical Society (EAS), the Islamic Crescents' Observation Project (ICOP), and the Center for Documentation and Research (CDR) organized an astronomical conference on “Applications of Astronomical Calculations” in Abu Dhabi on 13-14 December 2006 (22-23 Dhul Keadah 1427 AH). The participants, who numbered over 100 from 26 countries (Algeria, Australia, Egypt, France, Germany, Great Britain, Holland, Indonesia, Iran, Iraq, Jordan, KSA, Kuwait, Libya, Malaysia, Morocco, Norway, Oman, Palestine, Qatar, Singapore, Syria, Tunisia, UAE, Yemen, and USA), exalted the conference for its high scientific level and adopted the following recommendations:

  1. Set up a committee to evaluate the conference from all aspects and make recommendations for the next conference.

  2. Consider this conference as the first in a series of “Emirates Astronomical Conferences” and organize similar ones every two years.

  3. Adopt an Islamic Calendar based on crescent visibility calculations and strive to make it as widely acceptable as possible.

  4. Reject all testimonies of crescent observations that claim to break the well known records (Moon age, lag time, and particularly the Danjon limit) unless and until they are confirmed and accepted by the astronomical expert community.

  5. Include astronomers with expertise in crescent visibility in the official committees that determine the beginning of Hejric months.

  6. Continue and strengthen the studies of prayer times and publicize these studies.

  7. Start the study for the creation of a UAE national observatory for astronomical research.

  8. Introduce chapters and modules on applied astronomy in the educational curricula.

  9. Introduce regular newspaper and magazine columns and TV programs on Astronomy in place of Astrology, and publish Moonrise and Moonset times in the newspapers.

  10. Publish the proceedings book with high scientific standards at the earliest and distribute to libraries so as to make it a prime reference on the subject for all researchers.

  11. Publish a summary article about the conference in newspapers and magazines.

  12. Post the main recommendations and results of this first conference on the ICOP’s website and on partner websites.
