When are the northern lights visible?
They are normally only visible inthe sub-arctic and arctic regions. There is much mystery as to what causes them. Somewhat oddly they do not normally interfere with radio traffic but did cause some tuning problems ( which were compensated for by switching in resistances and compensations) in transatlantic telegraph message cables such as those at the French Cable station. The route of the cables was not in arctic waters. still things happen, the world turns. At one time in the late thrities the Aurora Borealis was visible in the New York Metro area- and the weather was cooperative an aunt of mine saw it. she said it looked like a barrage of distant strobe lights vaguely reddish on a movie screen or curtain. For some reason the phenomenon did not photograph. interesting question. the scientific name literally means Northern Dawn, as Aurora was the goddess of the Dawn.
