Islamic Crescents Observation Project (ICOP)

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. Please visit ICOP main page for more details.

This Month Crescent Observation Results: Rabee' Al-Awwal 1445

ICOP website contains a dedicated page for each Hejric (Lunar) month. This page contains the crescent visibility map for that month that shows the areas from which the crescent can be seen. The page also contains the crescent observation results of ICOP members which are located all over the world. In addition, the page contains the official beginning of that month in different countries. The visitor should be aware that each page contains the crescent visibility map and observation results for both; New (Waxing) crescent and Old (Waning) crescent.

Salat Calendar

“Salat Calendar” is a website to calculate prayer times anywhere on Earth, and to calculate alternative prayer times in Europe and northern areas when prayer times disappear or become at hardship times. It was created by the International Astronomical Center (IAC) with a sponsorship from Dubai Islamic Affairs and Charitable Activities Department (IACAD). One the features of the website is that it was prepared by specialized entities in astronomy and Islamic issues, hence it provides accurate times, taking into account astronomical and meteorological parameters, which were calculated accurately. As for northern areas when the times become late or disappear, the website initially shows the actual times without any alterations! Then it leaves the option to the user to keep the actual times or to calculate alternative times using any of the many available options in the Website. Salat Calendar can be used by the layman as it automatically determines the visitor’s country, and calculates the prayer times according to the parameters adopted in his country, and it can be also used by experts as it provides vast options which can be used to calculate payer times.

Satellite Reentry Watch (SRW)

Who we are?

Space debris continues to fall from the sky on a regular basis. Much of this goes unreported either because little attention is given to it by casual observers. SRW is a collaboration program between international experts in the field of artificial satellites and the International Astronomical Center (IAC). The need for this program arose after two satellite reentires occurred over Saudi Arabia in early 2015, ecpecially because there was no immediate explaination for the objects appeard in the sky at that time! As an average, there is betwen 0 to 5 reentries per day for tiny debris and approximately one big reentry per week for payloads, rockets and big debis.

Kindly Click Here to know more about this program.

SRW Objectives

The objective of SRW is mainly educational one. We aim to spread awareness on this subject to the general public and the astronomical community through the following methods:

• Send alerts to our members before an expected reentry.

• Ask the interested members to observe an expected reentry and report back their sighting.

• Discuss this subject in the mailing list of SRW to increase the knowledge of the members.

• Send news reports to the media, if required, about major reentries that were witnessed over large areas.

UAE Astronomical Cameras Network (UACN)

UAE Astronomical Cameras Network (UACN) is an activity done in cooperation between the International Astronomical Center (IAC) and the SETI Institute. It consists of several astronomical cameras located in different locations and are pointed towards the sky. The cameras automatically record a video file once a meteor is detected. This meteor might end up as just a meteor or a meteorite which could be a satellite debris reenty! In case the meteor is detected by one camera then there is a specific astronomical data that can be collected from the video using a special software. Whereas if the meteor is detected by more than a camera, then the astronomical data that can be obtained will be much more beneficial. Kindly Click Here to know more about UACN and to see the results and maps.

Accurate Times

for Windows

Accurate Times is the official program adopted by the Jordanian Ministry of Islamic Affairs to calculate the prayer times in Jordan. The program runs under Windows, and it calculates the following astronomical events:

1. Islamic prayer times (Fajer, Shuroq, Dhohur, Aser, Maghreb, and Isha).
2. Sun times (Beginning and end of twilight, sunrise, sunset, and Sun transit).
3. Moon times (Moon rise, Moon transit, and Moon set).
4. Moon phases (Geocentric or Topocentric).
5. Crescent visibility for both; new and old crescents.
6. Crescent visibility world map for both; new and old crescents.
7. Calculations for Sun and Moon ephemeris.
8. Qiblah direction (Direction to Ka'bah in Mecca).
9. Qiblah time .
10. Hejric-Gregorian conversion.
11. The prayer call (Athan) launches automatically when it is the time of the prayer.
