TAIPEI–Astronomy buffs will have to rely on luck to catch a glimpse of an annular solar eclipse on Monday, as heavy clouds are forecast across the island that day, the Central Weather Bureau said Saturday.

The rare phenomenon, last seen in Taiwan in 1958, is expected to take place at 4:56 a.m. on Monday, when the top right portion of the sun will gradually be covered by the shadow of the moon, which passes between Earth and the sun at that time.

An annular eclipse happens when the moon’s apparent diameter is smaller than the sun, which permits an annulus — the Latin word for ring — of the sun to be visible after it is obscured from view.

According to the bureau, the full eclipse is expected to occur at around 6:10 a.m. and last for three or four minutes.
