This can only happen during a new moon, when the Sun and Moon are in conjunction as seen from Earth. At least two, and up to five, solar eclipses occur each year; no more than two can be total eclipses.Total solar eclipses are nevertheless rare at any particular location because totality exists only along a narrow path traced by the Moon's umbra. There are four types of solar eclipses: 1- A total eclipse occurs when the Sun is completely obscured by the Moon. The intensely bright disk of the Sun is replaced by the dark silhouette of the Moon, and the much fainter corona is visible.
