Umbra, penumbra and antumbra of Earth and images that could be seen at some points in these areas (Note: the relative size and distance of the bodies shown are not to scale.)“… The Earth’s shadow has two distinct parts,… the UMBRA is the part of the shadow where all direct sunlight is blocked by the Earth; the PENUMBRA of the shadow is ...
What is the penumbra during an eclipse. The second shadow is called the penumbra. According to timeanddate.com, the penumbra is the lighter outer part of the moon’s shadow. It is the portion of ...
English: This diagram explains why the penumbra of a solar eclipse is approximately twice the size of the Moon. Since the Sun and Moon have nearly the same angular diameter, the umbra is reduced to nearly a single point in length. Therefore the three angles marked in red are nearly equal, all with a base equal to the Moon's diameter.
The diagrams to the right show the alignment of the Sun, Moon, and Earth during a solar eclipse. The dark gray region between the Moon and Earth is the umbra, where the Sun is completely obscured by the Moon. The small area where the umbra touches Earth's surface is where a total eclipse can be seen.
Diagram of the Wilson effect. The umbra is the darker inner circle and the penumbra is the lighter ring around the umbra. In astronomy, the Wilson effect is the perceived depression of a sunspot's umbra, or center, in the Sun's photosphere. The magnitude of the depression for the umbra is between 500 and 1000 km, with an average of 600 km. [1]
The Moon is at its closest to the center of Earth's umbra. U3 (Fourth contact): End of the total eclipse. The Moon's outer limb exits Earth's umbra. U4 (Fifth contact): End of the partial eclipse. Earth's umbra leaves the Moon's surface. P4 (Sixth contact): End of the penumbral eclipse. Earth's penumbra no longer makes contact with the Moon.
