Mirage of astronomical objects other quantities, the exact effects of atmospheric refraction on sunrise and sunset time cannot be predicted. Also note that this possible error increases with higher (closer to the poles) latitudes. Novaya Zemlya is a polar region in Russia.

The Novaya Zemlya effect will give the impression that the sun is rising earlier than it actually should or the sun is setting later than it actually should. Fridtjof Nansen wrote It is possible to observe the Novaya Zemlya effect in any place, where the temperature
