In addition to being a pretty cool band, NOAA is telling us that the Earth’s magnetic poles are moving more quickly than anticipated. An article on Space Weather’s newsletter says:

Space Weather News for Jan. 17, 2019
http://spaceweather.com
https://www.spaceweatheralerts.com

EARTH'S SHIFTING MAGNETIC FIELD: Earth's magnetic field is changing so quickly that researchers have been forced to update to the World Magnetic Model ahead of schedule. Developed by NOAA and the British Geological Survey, the model is widely used for precision navigation of devices ranging from nuclear submarines to the common smartphone. Your own phone may be affected. Find out how on today's edition of Spaceweather.com.

Above: Earth's magnetic north pole has been accelerating away from Arctic Canada since 1900. See http://wdc.kugi.kyoto-u.ac.jp/poles/polesexp.html

Maybe it's heading toward a pole-flip... It has happened about 12 times in the last 5 million years--the last being about 780,000 years ago. Some flips have reversed themselves again in as little as 200 years. I wonder how navigation would be when it happens! Maybe that makes it Australia's turn to be on the top half of the globe--Canada and Siberia on the bottom.
