Aurora Borealis and Aurora Australis, the Northern and Southern Lights occur simultaneously! They are part of a huge electric circuit powered by Earth's internal dynamo. Positive and negative, dancing in unison like Ying and Yang. How beautiful, wonderful and little-understood this planet is.At Tampa (Florida) International airport, runways are being renamed because of shifts in Earth's field. Runway 18 will be Runway 19, from 180 degrees magnetic North to 190 degrees. The magnetic North pole, presently located near Ellesmere Island in Northern Canada, was first located in 1831. Its location was nearly constant until 1904, when it started shifting at about 15 kilometres per year. In the late 1980's it sped up, and is now moving at nearly 60 kilometres per year.The South Atlantic Anomaly is a weak spot in Earth's magnetic field. The area beneath the SAA has much less shielding from cosmic radiation. International Space Station operations are planned to avoid this region. The anomaly is known to be growing and spreading westwards into the Atlantic. Some suspect ...
