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: timeanddate.com)

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.
