A planisphere is a simple hand-held device which shows a map of which stars are visible in the night sky at any particular time. By rotating a wheel, it shows how stars move across the sky through the night, and how different constellations are visible at different times of year. On this web page, a kit which you can download and print to make your own planisphere (for Brunei Darussalam) out of paper or cardboard.

Kertas kerja ini merupakan sebahagian daripada hasil penyelidikan yang bertajuk Pengaplikasian Rukyah dan Hisab di Asia Tenggara [(RUI)1001/CISDEV/816269] dan telah dibiayai oleh Geran Research University Individual (RUI), Universiti Sains Malaysia (2015–2016).
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.

Abstract. A new criterion for lunar crescent visibility has been established using 737 observations, almost half of them obtained by the Islamic Crescent Observation Project (ICOP). This criterion is based on two variables, viz. the topocentric arc of vision and the topocentric crescent width. The new model is able to predict the visibility of the lunar crescent both for naked eye and optically aided observations. From the database we found a Danjon limit of 6.4 degrees.
Introduction The lunar crescent visibility has been studied by many astronomers since the Babylonian era, with as a result currently more than 12 different criteria for lunar crescent visibility, based on a number of sightings in different lunar conditions. Many of these criteria were developed by Islamic astronomers, since a number of Islamic religiouseventsaredirectlyrelatedtolunarcrescentsighting.Forexample,thenew Lunar (Hijric) month begins on the next day of sighting the new crescent at west after sunset.
Buku ini adalah dihasratkan sebagai rujukan bagi ilmuan-ilmuan di Negara Brunei Darussalam dan sumbangan kajian berunsur saintifik. Di dalam buku ini terkandung kompilasi jadual waktu bagi kenampakan anak bulan yang pertama. Penghasilan jadual ialah dengan mengunakan berbagai-bagai perisian astronomi dan program yang diaturacara oleh Hazarry bin Hj Ali Ahmad.
Moon watchers can download this eBook Your Guide to the Moon, a supplementary edition in Astronomy magazine 2014, by Robert Burnham. It features moon watchers’ tips and moon maps which will guide you the location of lunar craters and maria visible in each lunar cycle from new crescent to last quarter. It will definitely aid your lunar observation. Download it here
Predicting the first sighting of the new crescent has been attempted since the time of the ancient Babylonians. The ancient methods of moon sighting depended on the astronomical calculation of the Moon and the time difference between moonset and sunset.
The first sighting of the new crescent moon is used as the basis of various calendars to signal the start of the new month. For instance, Islam requires that the sighting of the new crescent moon should be made with the naked eye.
