Total Eclipse of the Moon/Total Lunar Eclipse

I heard (from) the news that (a) total lunar eclipse (will) occurs tonight.
Total eclipse of the moon (It) is the (a) phenomenon that the moon looks like dark beacause of the shadow of the earth.
The shadows of the earth are maded by sunlight.
There are two kinds of shadows.
One is Penumbra that blocks off partial sunlight,
(and) the other is Umbra that blocks off all sunglight.
So, Umbra is the darkest shadow that receives no solar radiation.
When the sun, the earth and the moon are arranged (aligned), the phenomenon that/which the moon enters penumbra is called 'Penumbral lunar eclipse'.
And (Another) the phenomenon that/which the moon locates is in between umbra and penumbra is called 'Partial Lunar Eclipse', and lastly the phenomenon that when the moon enters umbra completely, (it) is called 'Total lunar eclipse'.
When total lunar eclipse occurs, the moon looks like red.
(On the other hand,) when total eclipse occurs, sunlight hidden by the earth can't reach the moon but the refracted light reaches the moon. (only the refracted light from the sun is visible.)
Red light which has the longest wave of the visible light is refracted well, so it reaches the moon. (The red light reflects on the moon's surface because it has the longest wavelength in the visible light.)
So the moon looks like red.
This total lunar eclipse was observed in (can be observed again after) 3 years.
But I saw the red moon dimly. Becuase (because the) clouds were overshadowing the moon.
I'm sorry that I couldn't see it clearly.

*Hope this helps. :)
