A total eclipse occurs when the observer is within the umbra, an annular eclipse when the observer is within the antumbra, and a partial eclipse when the observer is within the penumbra.
In an annular eclipse, the Moon passes directly in front of the Sun, but because of the Moon’s elliptical orbit, it’s a little too distant and small-seeming to obscure the entire Sun.
When the umbra does not reach the surface of the Earth, the Sun is only partially occulted, resulting in an annular eclipse.
Please be advised: It is never safe to look at a partial or annular eclipse, or the partial phases of a total solar eclipse, without the proper equipment and techniques.
