The Northern Lights, Aurora Borealis, is a light phenomenon that occurs in the Arctic sky on clear, dark nights, caused by solar winds interacting with the earth's magnetic field. The deep green and yellow colours, sometimes streaked with bands of red, are one of the most astonishing natural phenomena one can witness. They can be seen from September to April, but unfortunately their occurrence cannot be reliably predicted.
