An annular solar eclipse will occur on December 26, 2019. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. The annularity will be visible in Saudi Arabia, Qatar, United Arab Emirates, Oman, Pakistan, India, Sri Lanka, Malaysia, Indonesia, Singapore, Northern Mariana Islands, and Guam. Population centers in the path of the annularity include Kozhikode, Coimbatore, Jaffna, Trincomalee, Sibolga, Tanjung Pinang, Batam, Singapore, Singkawang and Guam.
