The penumbra is the outer shadow cone and is not as dark as the umbra.  A part of the Sun can be seen from within the penumbra. This shadow becomes less dark the closer you get to its outer edge.  So, if you are within the penumbral shadow of either the Earth or the Moon, you will see a partially eclipsed Sun.

The last component is the antumbra and is an extension of the umbra. This shadow is important only for annular eclipses, which will be detailed later. If you are in the Moon’s antumbral shadow, the lunar disk will appear smaller than the solar disk, and the Sun will be seen as a ring (or annulus).
