Northern Lights

Northern lights are formed when electronically charged particles from the sun collide with atoms and particles within the earth’s atmosphere. The lights’ colors are determined by the height at which the particles come into contact. At an altitude of approximately 90 to 200 km, the particles contact oxygen atoms, causing the most common green and yellow-green colors. Red, blue, and purple lights occur through the stimulation of nitrogen. The lights are most visible on clear nights and away from the light pollution of populated areas. The lights’ beauty can be magical and are an imperative sight for anyone visiting Iceland during winter. Several agencies offer northern light tours conducted in areas of more propensity for the experience. Below are links to websites with northern lights predictions.
