When do anular eclepes ocor?

Annular eclipses occur when the Moon passes between the Earth and the Sun, but the Moon is at a point in its orbit where it is too far from Earth to completely cover the Sun. As a result, a ring of the Sun's surface, or photosphere, remains visible around the Moon. This phenomenon typically happens during a new moon phase and can be observed from specific locations along a narrow path on Earth's surface. Annular eclipses occur several times a year, but they are not visible from all locations.
