I kid you not. According to recently analyzed satellite data, in August 2014, a “…1,000km-wide swirling mass of plasma” hovered “several hundred kilometers above the North Pole” for about 8 hours, raining electrons. Professor Mike Lockwood of the University of Reading, says the phenomenon “must be created by unusually large and rapid transfer of solar wind energy and charged particles into the Earth’s upper atmosphere.”
This may not be an unusual occurrance.
The fact the hurricane occurred during a period of low geomagnetic activity suggests they could be more relatively common within our solar system and beyond.
