UMBRA
You will see a partial eclipse if you are in the penumbra.
This is an eclipse of the moon.
The shadow is cast by the earth upon the moon.
During a total solar eclipse, the shadow is called the umbra. It is the darkest part of the shadow where the moon completely blocks the sun. The umbra creates the area on the Earth where a total eclipse can be seen.
The darkest portion of the Moon's shadow during a total solar eclipse is called the umbra. It is the region where the Sun is completely blocked and only the Moon's shadow falls on Earth, creating the darkest point of the eclipse.
You will see a partial eclipse if you are in the penumbra.
Solar eclipse (total or otherwise): at new moon. Lunar eclipse (total or otherwise): at full moon. -- Immediately after a Solar eclipse you get a new crescent moon appearing in the sky. Obviously therefore the eclipse happens at the point when the side of the moon that faces us is in total shadow - indeed during the eclipse we are covered by that shadow. -- Immediately after a lunar eclipse, as soon as the moon moves out of the shadow, it is full.
A solar eclipse occurs when the moon casts a shadow on Earth. A lunar eclipse occurs when Earth casts a shadow on the moon. Since Earth is larger than the moon, it casts a larger shadow, resulting in a longer eclipse.
Not precisely. The umbra is the TOTAL part of the shadow. In a total eclipse, where the eclipsing object is spherical, then the "inner" part of the shadow is the umbra, but in a partial eclipse, there IS NO umbra; just the "penumbra", the partial shadow.
This is an eclipse of the moon.
The shadow is cast by the earth upon the moon.
"Umbra" means "shadow"; specifically the darkest part of the shadow of a planet or moon during an eclipse.
During a total solar eclipse, the shadow is called the umbra. It is the darkest part of the shadow where the moon completely blocks the sun. The umbra creates the area on the Earth where a total eclipse can be seen.
That is a total eclipse of the sun.
Because the moon is small compared to the Earth, the shadow it casts isn't very large. The small size of the shadow and the rotation of the Earth mean that where you need to be to see a solar eclipse is very specific and changes from eclipse to eclipse. To see the next total solar eclipse, you'll have to travel to Northeastern Australia or North New Zealand on November 13, 2012. Good luck!
A Solar Eclipse, depending where you are in relation to the shadow, depends on whether you see a total Eclipse or a partial.
More specifically, a total lunar eclipse occurs when the moon passes through the umbra, the darker part of the shadow.
