An ‘annular solar eclipse’ is expected after Christmas day, on December 26. An annular solar eclipse happens when the moon covers the center of the sun but leaves a visible outer edge of the sun, thus forming a ‘ring of fire’ or ‘annulus’ around the moon. The ‘ring of fire’ marks the maximum stage of an annular solar eclipse.
The upcoming eclipse will be the last eclipse of 2019 and the central path will pass through Saudi Arabia, Southern India, Sumatra, Borneo, Philippines, and Guam. Moreover, a partial eclipse will be visible thousands of kilometers from the central path. The average duration of annularity is estimated to be three minutes and forty seconds.
In the Philippines, the phenomenon will be visible in some parts of Mindanao but will appear as partial solar eclipse for the rest of the country. According to the Philippine Atmospheric, Geophysical, and Astronomical Services Administration, the best sites to view the eclipse will be in Balut and Batulaki in Sarangani Island, Davao Oriental.
