Bandar Seri Begawan – People in Brunei Darussalam will be able to witness a Total Lunar Eclipse, or Blood Moon, on the evening of Tuesday, 3 March 2026, when the Moon turns a deep red colour as it passes into Earth’s shadow.

What Causes a Total Lunar Eclipse
A total lunar eclipse happens when the Earth moves directly between the Sun and the Moon, causing Earth’s shadow to cover the entire lunar surface. Even though the Moon is fully shaded, it does not disappear from view. Instead, it turns a reddish colour. This red hue is produced when sunlight bends through Earth’s atmosphere, allowing only red light to reach the lunar surface.

Where the Eclipse Will Be Visible Around the World
The astronomical phenomenon will be seen in the evening across Australia and eastern Asia including Brunei Darussalam, overnight throughout the Pacific, and at dawn in North and Central America as well as the far western parts of South America. A partial eclipse will be visible in central Asia and much of South America, while Africa and Europe will not see any part of the eclipse.

Visibility from Brunei Darussalam
The early stages of the eclipse occur while the Moon is still below the horizon in Brunei. The initial penumbral and partial phases will therefore not be visible locally. The eclipse becomes observable once the Moon rises already in partial eclipse, leading into the full phase of totality.

Key Eclipse Timings for Brunei
The Total Eclipse begins at 7:04 p.m., when the entire Moon enters Earth’s umbra and takes on a noticeably darker tone. This is followed by the Maximum Eclipse at 7:33 p.m., the moment when the Moon is deepest in the Earth’s umbra and appears most vivid red. Totality ends at 8:03 p.m., after which the Moon slowly brightens as it moves out of Earth’s shadow. The partial phase ends at 9:17 p.m., when the Moon is fully within Earth’s penumbra and only a subtle dimming remains.

Key timings in Brunei Darussalam Time (GMT+8) are as follows:

Penumbral Eclipse Begins: 4:44 p.m. (03 Mar 2026) [Not Visible from Brunei]
Partial Eclipse Begins: 5:50 p.m. [Not Visible from Brunei]
Totality Begins: 7:04 p.m.
Maximum Eclipse: 7:33 p.m.
Totality Ends: 8:03 p.m.
Partial Eclipse Ends: 9:17 p.m.
Penumbral Eclipse Ends: 10:23 p.m.

End of the Eclipse
The eclipse officially concludes when the penumbral phase ends at 10:23 p.m., marking the final stage of this celestial event. At this point, the brightness of the full Moon will return to its normal appearance.

A Deep Total Eclipse with Striking Visuals
This eclipse is classified as a deep total lunar eclipse, with a magnitude of 1.151, indicating that Earth’s umbra covers more than the entire diameter of the Moon. Totality lasts for 58 minutes, while the combined partial‑eclipse phases span more than 2 hours.

Viewing Conditions and What to Expect
The eclipse is safe to view with the naked eye and requires no special equipment. However, an unobstructed view of the eastern horizon is essential, as the Moon will be very low above the horizon when it first becomes visible.

A Dramatic Moonrise for Brunei
With a clear eastern horizon and favourable weather after sungkai, Brunei’s observers will see the Moon rising around 6:30 p.m., already more than half eclipsed, creating a striking and dramatic sight as it climbs above the landscape. As the eclipse enters totality, the Moon will gradually shift into a coppery‑red glow, with its colour shaped by natural atmospheric conditions such as humidity and fine airborne particles.

A Rare Ramadan Eclipse Before the Next in 2028–2029
This rare celestial event is especially significant as it falls in Ramadan. It is the last total lunar eclipse before the next one occurring on 31 December 2028 – 1 January 2029, which is visible from Brunei. For a total lunar eclipse that again coincides with Ramadan, the wait will be much longer: the next one that falls in Ramadan will occur on 7 July 2047 – 21 years from now.

Press Release:

English and Malay:

Bandar Seri Begawan – On the late night of Sunday, 7 September 2025, into the early hours of Monday, 8 September, the skies over Brunei Darussalam will host a rare total lunar eclipse.

A total lunar eclipse occurs when the Earth aligns perfectly between the Sun and the Moon, casting its umbra (central shadow) across the lunar surface. As the Moon passes through this shadow, it gradually darkens and transforms into a deep reddish hue, often referred to as a Blood Moon. This coloration is caused by Rayleigh scattering – the same phenomenon that paints sunsets red – as Earth’s atmosphere filters and bends sunlight, allowing only longer wavelengths to reach the Moon.

Unlike solar eclipses, lunar eclipses are safe to observe with the naked eye, and they can be seen from anywhere on Earth where the Moon is above the horizon during the event.

This eclipse will be visible across Asia, Australia, Africa, Europe, and parts of the Pacific and Indian Oceans. It is expected to be the longest total lunar eclipse since 2022, with totality lasting approximately 1 hour and 22 minutes, and the entire eclipse spanning over 5 hours. According to Timeanddate, an estimated 85.86% of the world’s population will witness at least part of the total phase, with 76.59% experiencing the full spectacle from start to finish.

In Brunei Darussalam, the 1.3619-umbral magnitude eclipse will be fully visible from start to end. Key timings in Brunei Darussalam Time (GMT+8) are as follows:

Penumbral Eclipse Begins: 11:28 p.m. (7 Sep)
Partial Eclipse Begins: 12:27 a.m. (8 Sep)
Totality Begins: 1:30 a.m. (8 Sep)
Maximum Eclipse: 2:11 a.m.
Totality Ends: 2:52 a.m.
Partial Eclipse Ends: 3:56 a.m.
Penumbral Eclipse Ends: 4:55 a.m.

Weather permitting, this will be a prime opportunity for photography and public observation. With 100% obscuration and 82-minutes totality, observers in Brunei will enjoy an uninterrupted view of the Moon’s transformation. Such long-duration total eclipses are relatively rare, making this event a highlight of the decade for skywatchers.

Above: A ranked list of total lunar eclipses in the 21st century, arranged by duration of totality from longest to shortest. The September 2025 eclipse holds the 28th position out of 85, making it one of the longest of the century.

This eclipse is part of Saros cycle 128, and is the 41st of 71 eclipses in the series. Occurring just 2.6 days before lunar perigee, the Moon will appear slightly larger than usual, enhancing the visual impact. The September eclipse also coincides with the Full Moon of Rabiulawal.

In Islamic tradition, eclipses are regarded as signs of Allah’s majesty, not omens tied to human events. The Prophet Muhammad ﷺ emphasized that: “The sun and the moon are two signs among the signs of Allah. They do not eclipse because of someone’s death or life. So, when you see them, invoke Allah and pray till the eclipse is clear.” – Hadith, Sahih Bukhari.

Press Release

The event was designed with two key goals: To make astronomy approachable and inspiring for the general public, including casual visitors to Jerudong Park, and to foster curiosity and scientific wonder through direct telescope observation of celestial objects.

Over 300 attendees, ranging from astronomy enthusiasts to first-time stargazers, gathered at walkway outside Jerudong Park Food Court during the three evenings to peer through telescopes and connect with the cosmos.

Main activities included:
i. Stargazing: Visitors observed the Full Moon at close-up view that revealed cratered surface, glimpsed of bright deep sky objects such as star clusters and identifying the constellation Scorpio.
ii. Interactive Guidance: PABD members were on hand to explain celestial phenomena such as the moon phases.
iii. Astrophotography: Many visitors took the opportunity to snap their own images of the Moon using smartphone cameras through telescope eyepieces capturing lunar surface at high magnification.

Various telescopes, including refractors, reflectors, and smart telescope models, were stationed around the venue, enabling visitors to experience different methods of observation.

Sidewalk Astronomy, originally popularised by amateur astronomers in 1965, gradually evolved into a global initiative embraced by the astronomy community. In Brunei Darussalam, this initiative was first introduced by PABD in 2007, inspiring the public to look up and reconnect with the wonders of the night sky.

“Some of our visitors had never seen the Moon’s surface in such detail—the craters, lunar highlands and the topography. For many, it was their first real experience with astronomy. Seeing their excitement and awe has been deeply rewarding for us as organisers,” shared Mohammad Husaini bin Ali Hassan, PABD member.

Press Release:

A solar eclipse occurs when the moon is perfectly aligned between the sun and the earth. During the partial eclipse, the moon never completely covers the sun.

The phenomenon of a partial solar eclipse will last for 2 hours 37 minutes, where throughout this celestial event, the Moon will obscure a small fraction of the sun. During the greatest eclipses, i.e. at 12.24 p.m., nearly 34 percent of the sun will be covered by the Moon.

People who wish to observe this phenomenon are advised not to look at the sun directly. Some of the safe methods of watching the sun eclipse are employed by using Shade 14 Welding Glasses, solar filters or by telescope projection.

Solar eclipse of the Sun is an uncommon phenomenon. The previous solar eclipse in Brunei happened on 21 Jun 2020. The next phenomenon of solar eclipse will occur again in Brunei on Thursday, 22 July 2028.

Press Release

Bandar Seri Begawan – People in Brunei Darussalam is set to witness a rare astronomical event when the Moon passes in front of the Venus causing the bright planet to temporarily disappear from the night sky on March 24, 2023.

During the lunar occultation, the Moon is perfectly aligned to pass in front of the brightest planet which is visible only from a limited part of the world.

The astronomical phenomenon will be visible from regions in South Africa, Indonesia, and South Asia including Brunei.

Observing Venus

Currently, the evening planet Venus shines brightly at magnitude -4.0, which makes it easily visible to the unaided eyes in sky after sunset. In fact, it is the third brightest celestial body in the sky after the Sun and the Moon.

An hour after sunset, Venus will appear like a bright “star” just a few degrees away from the Moon, which offers an eye-catching view of the two celestial bodies in the evening skies.

Timings of Occultation

If weather permitting, stargazers in Brunei should be able to see the brilliant “evening star” (which is in fact Venus) approaching close the Moon just before the occultation.

According to the International Occultation Timing Association (IOTA), Venus disappears behind the Moon at 8.05 p.m. from Brunei Darussalam. As this occultation involves the 3 day-old waxing lunar crescent, Venus will hide behind the unilluminated side of the moon.

The planet will then re-emerge from behind the moon’s sunlit edge approximately 28 minutes later, at 8.33 p.m. From Brunei, the reappearance will occur at a low altitude of about 2 degrees, and a clear unobstructed view of West horizon is needed to sight the unique event.

In the past, occultations was used for scientific purposes such as refining the Moon’s profile (e.g. shape of the lunar limb) and its orbit properties.

Rare Event

The last disappearance act of Venus behind the moon happened during the daylight of May 27, 2022. The Moon-Venus occultation from Brunei will not happen again until 16 years, on May 27, 2039.

Press Release

The celestial geometry of an occultation – the Earth, Moon and Venus are in a straight line. During the event, the Moon is perfectly aligned to pass in front of the brightest planet which is visible only from small segments of the world.

For the most region in Southeast Asia including Brunei Darussalam, this lunar occultation of Venus takes place in a daytime sky.

Observing Venus

Venus is the third brightest celestial body in the sky after the Sun and the Moon. Currently, the morning planet shines brightly at magnitude -4.1, which is easily visible in broad daylight sky for many experienced observers.

Less-casual observers may need an optical aid such as a telescope or binoculars and aim to the Moon crescent during the daytime to witness this occultation. Venus will be a few degrees away from the Moon hours before the occultation.

Timing of Occultation

If the sky is clear and blue, sky watcher in Brunei should be able to see a very bright “star” (which is in fact Venus) approaching close the Moon prior to the occultation.

Venus disappears behind the Moon at 10.58 a.m. for Brunei Darussalam. As this occultation involves the waning lunar crescent, at the beginning of the occultation, Venus will glide behind the bright side of the moon.

It will then re-emerge from behind the moon’s dark side approximately 1 hour 42 minutes later, at 12.40 p.m.

English & Malay

A total of 95 participants comprised of members of the Astronomical Society of Brunei Darussalam  (PABD), officers from Balai Khazanah Islam Sultan Haji Hassanal Bolkiah (BKISHHB), invited guests from local government agencies and higher education institutions, and also from regional countries from Malaysia and Indonesia, attended the workshop.

The closing ceremony was officiated by Haji Mahadi bin Haji Mohd Tahir, President of Brunei Astronomical Society. Also present at the ceremony was Dr Haji Mohammed Hussain bin Pehin Penyurat Haji Ahmad, Acting Director of Balai Khazanah Islam Sultan Haji Hassanal Bolkiah, Prime Minister’s Office.

In his closing remarks, Haji Mahadi addressed the significance of astronomical observation during the Golden Age of Islam in the 9th and 10th centuries as a source of learning and major achievements. 

“Medieval observatories became places for scientists and astronomers like Al-Biruni and Ibn Sina to gather for scientific discussions and perform astronomical observations. Observatories played an important role in enhancing the development of Islamic astronomy, where celestial objects were studied and led to astronomical innovations,” said Hj Mahadi.

“Since the establishment of the society in 2003, PABD has continually pioneered and developed multidisciplinary knowledge in the field of astronomy and Falak in Brunei Darussalam for the past 19 years.”

He further shared the Society’s aspiration in planning to construct an astronomical observatory for public use and scientific research purposes. “It is PABD’s ultimate vision to build an observatory in Brunei as a platform to expand astronomical knowledge including Falak Syarie in Brunei Darussalam.”

The PABD president also welcomed collaborations and partnerships from all agencies in realisation to set up an observatory, ”to build an observatory will require huge financial costs, and PABD as a non-profit organisation that operates for collective and public or social benefits, sponsorship contributions from companies and other agencies is one of the ways deemed appropriate to realise this big dream into reality.”

Workshop participants had the opportunity to learn and master the applications of a traditional Falak instrument, Rubu’ Mujayyab (Sine Quadrant), in effort to preserve the excellence of Islamic knowledge. The online session was facilitated by Ustaz Anuar bin Ariffin from Butterworth Religious Affairs Department, Pulau Pinang. 

Several key applications on the use of Rubu’ Mujayyab were demonstrated during the workshop such as obtaining local time from the Sun’s altitude, solving trigonometric calculations, measuring when the sun is directly overhead, determining the longitude and latitude of a location, calculate prayer times and also to calculate the Qibla direction.

The three day online workshop was jointly organised by the Astronomical Society of Brunei Darussalam  (PABD) in collaboration with Balai Khazanah Islam Sultan Haji Hassanal Bolkiah (BKISHHB), Prime Minister’s Office.

Press Release:

The workshop’s objective is to provide an opportunity to the public to learn the use of a traditional astronomical instrument, specifically the Rubu’ Mujayyab (Sine Quadrant) in effort to preserve the excellence of Islamic Astronomy (Falak Syarie) knowledge. It is also in line with the society’s main objective, which is to develop and strengthen the field of astronomy, especially Falak Syarie in Brunei Darussalam.

A Rubu’ Mujayyab activist, Ustaz Anuar bin Ariffin, was the invited facilitator of the workshop. He used to serve the Falak section at Pulau Pinang’s Mufti Department and he is currently working at the Religious Affairs Department Butterworth District in Pulau Pinang. He is also actively involved in teaching astronomy courses and has received numerous invitations from educational institutions and mosques throughout Malaysia.

The workshop will provide basic theory and practical training on the use of the Rubu’ Mujayyab. There will also be practical sessions during the day to further strengthen the participants’ understanding. Seven key topics were covered during the workshop highlighting on the applications of Rubu’ Mujayyab: Introduction to traditional Falak instrument; Method of obtaining time with the use of Rubu’ Mujayyab, Solutions to trigonometric calculations, Measurement when the Sun is overhead, Determining longitude and latitude; Calculation of prayer times and; Calculation of the direction of the Kiblat.

Prior to the workshop, participants were also instructed to create their own (DIY) printed Rubu’ Mujayyab based on the given template and instructional video provided by the organising committees.

Present during the online workshop last night was Dr Haji Mohammed Hussain bin Pehin Penyurat Haji Ahmad, Acting Director of Balai Khazanah Islam Sultan Haji Hassanal Bolkiah, who officiated the opening ceremony.

In his speech, Dr Haji Mohammed Hussain stated that one of the nine galleries at BKISHHB – Gallery 8 is an Astronomy Gallery exhibiting various traditional astronomical instruments such as Astrolabe, Rubu’ Mujayyab and Rubu’ Mujannah. Therefore, this workshop is in line with the role and function of BKISHHB and is amongst the efforts to support and realise the BKISHHB’s strategic goal which is to become a heritage centre for Islamic Knowledge that is
capable of cultivating knowledge by conducting educational activities. This will also open opportunities for BKISHHB to conduct research with strategic partners that has the knowledge and expertise in specific fields.

He also mentioned that despite the current pandemic, this should not deter us from conducting any educational activities. The response from the public to participate in this workshop was encouraging as in a very short period of time registration had to be closed early due to reaching the maximum limit. There were 95 individuals who had registered for the online workshop and 7 of these were participants from neighbouring countries: Malaysia
and Indonesia representing several educational institutions and astronomical societies in the region.

Among the attendees of the workshop was Haji Mahadi bin Haji Mohd Tahir, the President of PABD, Executive Committees of PABD, Officers of BKISHHB as well as invited guests from government agencies and higher education institutions who are also participants of the workshop.

Rubu’ Mujayyab is believed to have been popularised before the 8th century. Al-Khawarizmi (770-840) was one of the scholars that benefitted through the use of this instrument to calculate prayer times. Linguistically, Rubu’ means a quarter, and Jayb means a shirt’s pocket. Al-Biruni defined jayb as Sine. In English, it is known as the Quadrant. In terms of terminology, the Rubu’ Mujayyab is defined as a traditional astronomical instrument created specifically to measure angles and time to calculate prayer times, direction of the Kiblat and the beginning of the Islamic month.

Bandar Seri Begawan – A partial eclipse of the Moon will happen on Friday evening, November 19, 2021, and will only be observable for about 46 minutes from Brunei Darussalam.

A partial eclipse occurs when the earth moves between the sun and the moon, but the three celestial bodies do not form a perfect straight line.

The phenomenon will be visible in our country Brunei Darussalam and much of Asia, Australia, North America, South America, Pacific, Atlantic and Arctic.

During the eclipse, some part of the Moon will slide into the Earth’s darkest shadow known as umbra. From Brunei, the eclipse will start when the moon is still below the horizon.

Eclipse watchers in Brunei can observe the astronomical wonder only when the entire moon is above the horizon until 6.47 pm.

Weather permitting, Friday moon eclipse promises to be a dramatic sight – our natural satellite hangs just above the horizon will be half-covered by the Earth’s shadow from Brunei at moonrise, about 6.01 pm.

Since the Moon is near the horizon at this time, observing at a high vantage point or finding an unobstructed sight (free from building, tall trees, etc) to East-northeast is highly recommended for the best view of the eclipse.

The Moon then slowly moves through the faint, outer part of Earth’s shadow known the penumbra, for 1 hour and 16 minutes, from 6.47 pm until 8.03 pm. During the penumbral phase, the eclipse is much more subtle. Often the darkening on the moon is less noticeable, and most observers will only just see the ordinary full moon.

The next lunar eclipse will happen in Brunei on 8th November 2022, which is a total.

Press Release

From September until October, six Bruneian groups comprise of 30 members (see participants list here) were working under IASC Asteroid Search Campaign co-organized by the Nepal Astronomical Society (NASO) and the Astronomical Society of Brunei Darussalam (PABD).

During the campaign, participants from Brunei and around the world used an advanced astrometry software to analyse photographs and real sky data provided by the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) telescope in Hawaii.

It involved observing the Near-Earth objects and Main Belts asteroids and reporting for unknown asteroid detections. Information from these preliminary findings will be further study which can take up to 5 years to define the asteroids’ orbit by professional astronomers.

The preliminary asteroid detections by the six Bruneian teams – the Astronomical Society of Brunei (PABD), Hulubalang Brunei, Laksamana Brunei, Panglima Brunei, Pateh Brunei and Semaun Brunei – were confirmed in reports produced by IASC, Hardin-Simmons University, on Thursday, November 04, 2021 (see reports here).

The campaign offers opportunity for people in Brunei to discover new asteroids. It serves to promote scientific research by working on the real time data collected by astronomical observatories to detect any new asteroids.

Next year, PABD will organize the first All-Brunei Darussalam Asteroid Search campaign in collaboration with IASC which will commence from January. It will run regularly and open for citizen scientists and students to enable the discovery and tracking of more asteroids.

This way, it also inspires a growing interest for science amongst our community especially our students.
