The infographic shows the position of the Moon crescent relative to the Sun’s position about the Western horizon at local sunset, and its predicted visibility based on New Criterion for Lunar Crescent (2005) by Mohammad SH. Odeh. Also presented on the graph are the minimum lines of different criterion to start the new Hijrah month adopted by different country/organization.

Sighting the new crescent on April 01, 2022, is shown in the chart for selected cities. In summary, the Moon is below the Danjon’s Limit and not sufficiently illuminated in order to be seen as a crescent from many region globally. The moon crescent may be seen with difficulty in Hawaii and westernmost part of the world.

These are pre-calculated data, the actual start of the fasting month of Ramadan should be referred to your country’s official authority.

Members had the opportunities to learn setting up telescopes properly, scopes alignment to the sun or other bright objects, photographing and tracking the new moon. The western sky was pretty clear at sunset, and a sunspot was also visible on the sun.

Abstract

There are various methods used to determine the arrival of Ramadan (fasting) and Syawal in South East Asia. Malaysia and Indonesia use the rukyah (sighting of the moon) and hisab (mathematical calculations), Singapore uses the hisab while Brunei only uses the rukyah method. These differences are due to the different basis for using a certain method to determine the arrival of Ramadan and Syawal. The basis here refers to religious references and forms of istidlal (inferences). The question is, what religious references are used to substantiate the adoption of the rukyah method in Brunei? What is their form of istidlal based on the religious references? To answer all these questions this study has two objectives. Firstly, it intends to determine the religious references that act as the basis for using the rukyah method in Brunei. Secondly, to analyse the different forms of istidlal based on the religious references. In order to achieve these objectives, this qualitative study used library research and expert interview methods for collecting data. All the data were analysed using the content analysis method. Lastly, this study concluded that religious references from the al-Qur’an and Hadith used as a basis for applying the rukyah method in Brunei is similar to the religious references used as a basis for applying rukyah and hisab in other South East Asian countries. The only difference is the various forms of istidlal.

The following is the astronomical calculation of the moon for Bandar Seri Begawan, Brunei, on the day of Syaaban 29,1436H corresponding to June 16, 2015
1. Sun sets at 18:32 (Local Time)
2. The moon sets at 18:18.
At sun sets,
3. The angular seperation of Moon-Sun is 5.31°
4. Moon Azimuth is 288.75°
5. Sun Azimuth is 293.50°
6. Moon age is 29.3 day old or -3.6 hour before conjunction.

In conclusion, the moon is a waning crescent, that is not a New Moon, and not observable as it sets earlier before the Sun goes down. However, the starting date of fasting in Brunei will depend on the official announcement on that evening.
