Day and Night
There is a technical term for the part of the earth that is in light and the part in shadow. Other than the obvious Day/Night/Light/Dark, has anyone any ideas???

Light & dark? :p
|
Well, when in an eclipse, the really dark bit is the umbra, and the not so dark bit is the penumbra. Not sure if this applies if the shadow is being cast by one's own planet:confused:
|
Where the boundary between dark and light is called the terminator.
|
And on the other side of the earth it's called the Terminator 2
Not stalking you reddo, honest! :) |
Thank you, that is what I am after....
|
And the catch phrase for both dark and light is "I'lll be back":)

Are you referring to Morning Civil Twilight and Evening Civil Twilight?
These are the times of day between when the upper limb of the sun is 6 degrees below the horizon and the upper limb of the sun appears upon the horizon. |
Not MCT or ECT, but thanks anyway. I mean the two bits that you would see if you were viewing from outer space. Half dark and half light. They have a proper reference name.

Half dark and half light |
