A solar eclipse will be visible in Jaffna tomorrow (December 26) and move in a northerly direction, according to Astronomers.It 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
