The cloud is moving toward us.

Explanation:

When objects are in space or air, and this is true for most objects in the universe, they move in relation to the sun or their movement can be recorded in relation to the sun. As the object moves away from the sun, the wavelength decreases. This causes a shift in the spectrum mainly towards blue or violet. Here, this is clearly mentioned in the given statement. This mean that the object or cloud is moving towards us.
