The corona.
People in the penumbra during a solar eclipse will see a partial eclipse, where the sun is only partially covered by the moon. This results in a crescent shape of sunlight rather than a total blockage. The amount of sunlight that is blocked will depend on how close they are to the umbra, the central region of the shadow.
the moon can be seen during a solar eclipse it's during a lunar eclipse you can not always see the moon. Because it travels through the shadow cast by the Earth

If it is a lunar eclipse they see the shadow of the earth cross the surface of the moon. If it is a solar eclipse, they see the moon pass between the earth and the sun. NOTE: One should not look directly at the sun at all, even during an eclipse.
