If you're referring to an eclipse:
* Solar eclipse: This occurs when the Moon passes directly between the Sun and Earth, blocking the Sun's light.
* Lunar eclipse: This occurs when the Earth passes directly between the Sun and Moon, casting a shadow on the Moon.
If you're referring to the Sun and Moon appearing in the same part of the sky:
* Conjunction: This is a more general term that means two celestial bodies appear close together in the sky. This can occur with any two celestial bodies, including the Sun and Moon. It doesn't necessarily mean they are actually close together in space.
If you're referring to the Moon passing through the Sun's path:
* Lunar transit: This is a rare event where the Moon passes directly in front of the Sun, but it's not a full eclipse because the Moon is too far away from Earth to completely block the Sun's light.
So, the specific term depends on the specific scenario you're referring to.
