Our star has magneticly flipped over.

Not sure exactly how the pagans would celebrate such a thing, but we at ORR.net are likely to turn on a radio and have a listen.

Yeah, it does that. It's an oscillator, with a frequency of about .00000144 Hz. Wavelength is about 22 light-years.

Not a very good oscillator, either -- lots of phase noise.

The sun is not the only "magnetic pole flipper."

The earth's magnetic poles also flip, but the period is much longer.

Navy mapping of the Atlantic sea floor shows the same phenomenon happens to the earth, but on a much longer time scale.

According to the historic record the "event" is several thousand years overdue; BUT


The magnetic north pole is moving now and the rate of change is accelerating. http://www.nasa.gov/topics/earth/features/2012-poleReversal.html

Oh boy! I wonder what THAT is going to do to HF propagation!
