The Midnight Sun is a period during which the Sun remains visible for over 24 consecutive hours, caused by the tilt of the Earth's axis.
In Russia, locations such as Murmansk, Norilsk, Dudinka, Salekhard, Khatanga, and Pevek experience the Midnight Sun, where the sun does not set for an entire day. This phenomenon contrasts with the Polar Night when the Sun does not rise for more than a day.
