Sometimes 2 aureolas are alike, some aren’t
“areaolas braless in Antarctica” didn’t bring up helpful search results but did suggest that some rather underdressed people claim to reside in colder climes.
I would recommend refining your search terms.
Also there is the tilt of the earth. Maybe that can affect the aurora displays.
Guessing that you have spent a great amount of time studying this subject?
Be that as it may, about the spelling?
Areola???
