Aurora BorealisIn 1719, the first recorded sighting of the Aurora Borealis took place in New England. The report said that a mysterious face seemed to appear in the atmosphere. It caused considerable alarm, as being regarded by many as a precursor of the last judgment. Most aurora borealis displays occur in September and October and again in March and April. The green, red, and frost-white light displays occur most frequently when there is a great deal of sunspot activity. "This evening, about eight o'clock there arose a bright and red light in the E.N.E. like the light which arises from a house on fire ... which soon spread itself through the heavens from east to west, reaching about 43 or 44 degrees in height, and was equally broad." |
