Annular Solar Eclipse-Chasing Expedition from 23rd until 28th December 2019

Bandar Seri Begawan – On Dec 26, 2019, an annular solar eclipse will occur from few cities in Borneo, on the narrow track of the Moon shadow. Yes you have you be along the eclipse path to witness this special kind of eclipse of the sun – and we will bring you there! The celestial alignment happens when the moon passes in front of the sun, but the orbit of the moon is a little further away from the Earth and the moon does not completely cover the sun.

It will be a very spectacular sight, when a “ring of fire” or annulus surrounds the sun at central eclipse. Watch a “string of beads” (Baily’s Beads Effect) on the edges of the sun during the beginning of annularity eclipse. As the horizon darkens to deeper blue than normal, observe the animals reacting to the dramatic changes in the sky. Look for the brightest planet, Venus, shining east of the sun at mid-eclipse. Jupiter, Saturn and Mercury are up there too, but they are fainter and so will be harder to see. This is a rare celestial event as the next annular eclipse will take place in Borneo in 2031.

The visible surface of the sun in a fiery ring around the moon can still blind you. So be sure to watch indirectly, or with special filters. Do not look at the sun directly without eye protection at any time during this eclipse. PABD will provide each member with an eclipse glass (included in your package) for this expedition.
