False Sunset

Yesterday, I had the chance to witness an event called false sunset.

This event can refer to any of the following atmospheric optical phenomena:

1) the sun appears to be setting below the horizon, while in reality it is still some distance above it

2) the sun has already set, but still appears to be on or above the horizon.

There are several atmospheric conditions which may cause the effect, most commonly a type of halo, caused by the reflection and refraction of sunlight by small ice crystals in the atmosphere, often in the form of cirrus or cirrostratus clouds.
