Mercury rise and set in Troll Station
Up some of the night.
Mercury is visible more than 4 hours during the polar night. It is very close to the horizon, making it fainter because the light has to cover a larger distance when traveling through the Earth's atmosphere. Make sure to get an unobstructed view with as little light pollution as possible.
