The sighting of the new moon is a particular subject in astronomy that has fascinated many observers since prehistory. Evidence of early human civilizations using the moon as a basis to measure time in the form of an actual lunar calendar has been discovered in the ancient plains of Scotland, dating back to 8,000 B.C. Professor Samuel L. Macey of the International Society for the Study of Time in his book, Encyclopedia of Time, says that using the moon to measure the passage of seasons was evident as far back as 28,000-30,000 thousand years. Therefore, the method by which we measure the beginning and the end of the new moon phase is indeed a crucial part of determining the accuracy of any lunar calendar.
Since the Islamic months follow a lunar calendar, the start of each month is marked by the first sighting of the crescent moon. It is important to note however, that the Islamic new moon is actually different to the “astronomical new moon”. We define the astronomical new moon as that point when it is in conjunction with the sun, and thus it is actually too close to the sun and is very dark, for most of the lunar disc is in shadow. This point marks the beginning of measurement for the true age of the moon.

Here is the challenge – What’s the
youngest moon you can see this year? The infographic will tell you when to hunt
the new moon crescent (hilal),
and where to locate its position in the western sky at sunset from Brunei
Darussalam in 2020.
Note: Prediction method by Mohammad SH. Odeh (New Criterion For Lunar Crescent Visibility, 2005) employed new criterion visibility of the lunar crescent, V. This is only a computational analysis data. The result/declaration of the sighting/beginning of hijrah month should be referenced to official media by the Government.
Bandar Seri Begawan – The Western sky was clear on the evening of August 31, 2019. The celestial objects, Venus and Sun, were used for scopes alignment during the new moon sighting.
The new moon observation of Muharram 1441H was held at Agok Hill by members of Astronomical Society of Brunei Darussalam. The 24 hour-old hilal (crescent moon) was sighted immediately after sunset, 6.28 pm (after pointing the scopes at sunset and slewing to the Moon).
PABD wishes all Muslims in Brunei Darussalam and around the world Salam Maal Hijrah 1441H.
Brunei Darussalam will determine Hari Raya Aidiladha with a moon sighting of month of Zulhijjah 1440 Hijrah nationwide on 29 Zulkaedah 1440 corresponding to 1st August 2019 at several designated areas in the three districts.
In the Brunei Muara District, the moon sighting will take place at the DST Tower of DST Headquarters building, Tungku Highway, Bukit Agok Jerudong, Tanjung Batu and Kampung Sabun. Meanwhile in the Belait District, Bukit Lumut and Bukit Ambog di Tutong District. The outcome of the moon sighting will be broadcast through Radio Television Brunei as soon as the result is received.

The new moon was not seen from various vantage points in Brunei due to very thick clouds.Present at the observing site was Yang Dipertua Hj Mahadi bin Hj Md Tahir, the president of the association.
Here’s our cosmic idea for school holiday activities – Lunar Crescent Marathon!
Go out to look for the daily changing moon crescent in early morning, before sunrise, on May 27 until Jun 02 2019 for the Waning and Old Crescent in the Eastern sky. Continue your observation on evening of June 04 until June 10 2019, shortly after sunset, for the New and Waxing Crescent in the Western sky.

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.
Borneo Bulletin – TWO working papers on the use of modern technology for the sighting of crescent moon (Hilal) were presented during the Falak Syar’ie parallel session at The Rizqun International Hotel, Gadong yesterday.
The parallel session was part of the 14th Southeast Asia Survey Congress (SEASC) 2017 organised by the Ministry of Development’s Survey Department, in collaboration with the Brunei Institution of Geomatics (BIG), under the auspices of the Asean Federation of Land and Geomatics Survey (AFLAG).

In his presentation on ‘Imaging Method for Crescent Moon Sighting with the Charge Couple Device (CCD)’, Haji Julaihi bin Haji Lamat, from the Brunei Institute of Geomatics, introduced the CCD as a technology that was born in 1969 at the AT&T Bell Labs, and has since undergone vast improvements with modern software.
Due to the recent outbreak of the 2019 Novel Coronavirus (Covid-19), the Astronomical Society of Brunei Darussalam (PABD) has postponed most of our public engagement activities such as stargazing, new moon observation etc. until further notice and focus on implementing Astronomy at Home or in a small group activity. This is in view of prevention and to control the spread of the infection in Brunei Darussalam.
