A huge shelf cloud appeared to cut the sky in half.

As Carl Pescettini filmed outside in Christiansø, Denmark, on June 15, the giant cloud formation appeared overhead.

Stretching the full length of the horizon, the cloud seems to break the sky in half as the colours change dramatically from light to dark grey.

Carl said: “It looks like the sky is cut in half, but it’s two big different coloured clouds touching each other.”
