: the Moon does not cover the entire solar disk appears as a crescent. Total
: from a band (band of totality) on the surface of the Earth, the Moon completely covers the Sun Unsubscribe: occurs when the Moon near the peak and angular diameter is less than solar, so that at the peak ring is visible disk of the Sun This is in the band, outside the eclipse is partial.
