New Lunar Crescent of Syawal 1437 seen from Brunei

Bandar Seri Begawan – July 05, 2016. A group of members of the Astronomical Society of Brunei Darussalam was at the Agok Hill in Tutong for the moonsighting to observe the new moon of Syawal 1437H. The western sky was partly cloudy especially new the horizon with the sun set behind the clouds on that evening. At about 15 minutes after sunset, at the clouds break, the 24 hour old hilal was firstly visible through telescopes and CCD Camera at around 6.52 pm.

Brunei to See Partial Solar Eclipse on March 9 2016

Solar Eclipse Banner

What happens during a partial solar eclipse?

A perfect  alignment of the Earth-Moon-Sun bodies is required for a solar eclipse to occur. As seen from a location on Earth, a solar eclipse happens when the moon moves in front of the Sun thus block the Solar Disk. A simulation of the partial Solar Eclipse as seen from Brunei in the morning of March 9, 2016 is shown in the video above. Since we will only witness the partial obscuration of the sun by the moon, features that are normally visible during totality such as corona and darkening of the sky/surrounding will not be observable from Brunei.

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.

Brilliant Geminid Meteor Shower Dazzles Brunei Sky

Bandar Seri Begawan – In the predawn hours of December 13, 2015, as the Earth began to sweep through a dense remains of debris from asteroid 3200 Phaethon, these falling space debris burned up in the atmosphere and caused bright flashes in the sky known as shooting stars or geminids meteor showers.

The Geminid shower got its name from the constellation of Gemini or the Twins. From Tutong, there were about 10 meteors in an hour visibled on that morning. The rate is expected to increase as the annual geminid meteor shower peaks tonight (13-14 December 2015). That is when more than 50 shooting stars might be visible every hour (depending on your location/sky). Geminids can be spotted starting between 10 pm and before sunrise, and expected to peak at around 2 am. Continue reading “Brilliant Geminid Meteor Shower Dazzles Brunei Sky”

Mini Astronomical Observatory Opens Window to Brunei Sky

Panorama-Observatory

 

Tutong – On July 18, 2015, a local astronomy enthusiast dedicated a backyard mini observatory, a roll-off roof structure housing a 152mm refractor telescope, at Keriam in Tutong, Brunei Darussalam that is available for public use. With the completion of the sliding roof observatory, Astronomy in the Brunei is hoped to move a step forward as the observatory opens a whole new window into the universe for community.

New Criterion for Lunar Crescent Visibility

By MOHAMMAD SH. ODEH, Arab Union for Astronomy and Space Sciences (AUASS), P.O. Box 141568, Amman 11814, Jordan (e-mail: modeh@auass.org)  (Received 12 May 2005; accepted 19 September 2005)

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.
