Description
Different kinds of solar and lunar eclipses possible
| Value |
Meaning |
| none |
No eclipse at all. |
| partial |
Partial eclipse, just a segment of the sun is obscured. This happens when the center of the moon disc and the sun disc do not meet |
| noncentral |
A total eclipse, but without the centers of the shadow region hitting earth, so only the polar regions get into the total area of the shadow. |
| circular |
Because of a different size of the discs there remains an illuminated ring around the shadowed part of the sun. Also called annular eclipse. |
| circulartotal |
An eclipse which is total on part of the ground track, and circular on another part. |
| total |
A total eclipse. |
| halfshadow |
For lunar eclipses only. The moon is not hit by the full shadow, but because of the distance from earth being too large only hit by the penumbra (half shadow). |
