penumbral lunar eclipse, this is when the moon passes through the the earth's penumbra
partial lunar eclipse, when the moon enters the earth's umbra
warninggg: this is not an accurate cycle of lunar eclipse phases. i just edited the pictures into this for fun. it is in fact too far from being accurate, there would be no reason for you to steal this picture and claim it to be yours. well, it could be an accurate model, probably in parallel universe. oooooohhhhhh~
So yeah I missed the part when the moon was completely in the umbra region. due to light refraction on the earth surface, the moon appears to be reddish even though it is actually in the darkest area of the shadow. okthnxbai.
