Default Polar dawn

The first glimpse of Polar dawn are setting in at the South Pole, where, in just over 5 weeks the Sun will come into view for the first time in 6 months as the Earth slowly turns parallel to the orbital plane and as a function of the Earth's orbital motion -

Pity they have installed a $50 webcam to mark the one and only event of its kind at the South pole each orbit but then again researchers at habitable latitudes are oblivious to the fact that the planet will turn once each orbital circuit to the Sun aside from and in addition to daily rotation.

People those come to appreciate these thing at academic junkets like conferences, they can enjoy the spectacle in their own way and their own time once they give the Polar day/night cycle and its cause consideration. The polar day/night cycle offers a different astronomy due to its unique cyclical traits that exist nowhere else on the planet.
