Northern Lights trump street lights in Iceland
Reykjavik - Agence France-Presse
Most parts of the world's northernmost capital city, including the centre, will go dark from 10:00 pm.
"Residents are invited to join in by turning out the lights at home so as to maximise the darkness and minimise light pollution," the local government said in a statement.
The Aurora Borealis, or Northern Lights, are multicoloured natural illuminations caused by interactions between solar winds and the Earth's magnetic field.
