Sun rays often play in the sky giving beautiful effects. Before sunset you often see the sun rays opening the sky in a top-to-bottom effect.

Shortly after sunset, when the sun is just below the horizon, you get the opposite bottom-to-top effect.

Another example of top-to-bottom effect about an hour before sunset.

The beautiful ancient city of Chefchaouen. Moments before it was raining.

Yet another beautiful African sky. Here the sky is opening into the famous Ngorongoro crater in Tanzania. The crater lake is seen inside.

Beautiful early morning in the sunshine state.

This unusual ray formation is just at sunset, but without any visible clouds in the sky. Note how different shades of pink and blue are displayed upwards from where the sun is located just under the horizon.

Similar in presentation to the Zambian one above, this moment was followed by a spectacular sunrise on the top of Japan's highest mountain, Mt. Fuji, 3776 m above sea level.
