Oh to be in Borneo! On Monday, Jan. 26th, inhabitants of that heavily forested island will witness the sunset of a lifetime. Just as the sun descends into the waves of the Indian Ocean, the Moon will pass in front of the sun--dead center--covering 93% of the solar disk. The ensemble will form a stunning "ring of fire," something like this:

Similar sunset rings will appear over the nearby islands of Java and Sumatra: map. Astronomers call such an event an annular eclipse.
Elsewhere, the Moon will pass off-center producing crescent suns of varying depth over south Africa, Madagascar, Australia, southern parts of India and southeast Asia. Sky watchers in those places should attend to the ground: crescent sunbeams will dapple the earth beneath leafy trees and garden latticework. Stay tuned for photos!
