2019 Dec 26 Annular Solar Eclipse: ‘Ring of Fire’ in Borneo, Brunei merely misses it will still see partial eclipse

By Hazarry bin Haji Ali Ahmad

Bandar Seri Begawan – A perfect  alignment of the Earth-Moon-Sun bodies will occur on December 26, 2019, resulting in a spectacular annular solar eclipse visible in few cities of Saudi Arabia, India, Sri Lanka, Sumatra, Borneo and the Pacific Ocean .

Distinct parts of a Moon’s shadow on the Earth – Antumbra and Penumbra. A bright ring is visible around the eclipsing bodies from area of Antumbra. An annular solar eclipse happens when the Moon covers the Sun’s center, leaving the Sun’s visible outer edges to form a “ring of fire” or annulus around the Moon. (Photo Source:

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. It is a mere miss, as people in Brunei will only see a partial eclipse with 85.8% obscuration of the Sun by the Moon. A simulation of the partial Solar Eclipse as seen from Brunei during mid-day is shown in the video below.

Since we will only witness the partial obscuration of the sun by the moon, features that are normally visible during annular eclipse such as ring of fire and darkening of the sky/surrounding will not be observable from Brunei.

Make your own cardboard planisphere

Adapted from Dominic Ford

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.

2019 Feb 19 Hypnotising Supermoon Lights Up Brunei Sky

Bandar Seri Begawan – An unusual full moon light “hypnotised” many skywatchers to a rare celestial display around the world including Brunei Darussalam on Tuesday night, 19 Feb 2019.

The super moon was the biggest and brightest in 2019 because its orbit is at its closest to earth or at perigee at around 356,800km.

At such shortest distance, the Earth’s only natural satellite appeared nearly 30% brighter and almost 14% bigger than a typical full moon. Some effects of the moon’s gravitational pull at our oceans was more pronounced than other times of the month, generating higher than normal high tides or Spring Tides.

Below, some of the best shots of it from around the Sultanate.

Comet Y1 Iwamoto Tops Out in February – Every year produces a handful of binocular comets, and the first one for 2019 is coming right up, with a fine apparition for Comet C/2018 Y1 Iwamoto.
Discovered by Japanese amateur Masayuki Iwamoto as a +12th magnitude fuzzball moving through the constellation Hydra the Water Serpent on the night of December 18th, 2018, Y1 Iwamoto is a fast mover. It’s great to see that amateur astronomers can and still do discover comets, as the robotic competition posed by automated surveys such as PanSTARRS makes such an independent discovery tough these days. And to think, the next generation of really powerful surveys such as the Large Synoptic Survey Telescope (LSST) has yet to come online… I wonder how many hidden comets and asteroids lurk in the latest PanSTARRS data dump?
