Living in Belleville, Ontario (north shore of Lake Ontario, about the midpoint running east-west), in the mid 1960's I recall two incidences between roughly November 1965 and February 1968 when the aurora borealis (northern lights) was so bright and high in the sky that we noticed from our living room, above the houses just across the street.
Even seeing the aurora in the vicinity of Belleville today, even in a darkness preserve, seems outrageously far fetched as it is never visible within a couple of hundred miles. The notion of detecting it from inside a lighted room, even faintly, likewise approaches absurdity for most of the populated regions of Canada.
It is updated several times hourly and of course varies with solar conditions, but here is a 30 minute Aurora Forecast projected from solar flux currently detected at Earth's L1 Lagrangian point (with a history of the past 24 hours). As is clearly apparent, the aurora is almost never visible anywhere near the locale of Belleville, Ontario.
Is it possible to identify the solar events or effects that caused the aurora to be visible so far south?
