Did you know? Here’s a space weather and radio propagation educational tidbit – from http://SunSpotWatch.com – at 14:00 UTC on 2017-05-27:

The equatorward migration of the auroral ovals (the northern and southern auroral ovals) is a common feature of auroral substorms. During enhanced periods of geomagnetic activity, the auroral zone expands equatorward into the non-auroral zone (the zone where aurora is not common, but are quite rare).

The auroral ovals are offset from the rotational poles of the Earth. Auroral zones continually change, too.
