Auroras are visible almost every night near the Arctic and Antarctic Circles, which are about 66.5 degrees north … Normal outdoor activities may be carried out because there’s light scattering due to atmospheric refraction. Research has long documented that people of all ages – elementary school children, college students, and adults – cannot explain the cause of day and night or seasons. timeanddate.com.
