EARTH'S MAGNETIC FIELD IS RINGING LIKE A BELL: Today, a high speed solar wind stream is passing just south of Earth, making grazing contact with our planet's magnetic field. This is causing something unusual to happen. Around the poles, Earth's magnetic field has been ringing like a bell. Rob Stammes recorded the phenomenon from his magnetic observatory in Lofoton, Norway.

 

The effect of this solar wind stream may be likened to a person blowing across the top of a soda bottle, the glancing breath producing a nearly monochromatic waveform. "This is quite rare," says Stammes. "Pulsating continuous signals like these are visible only 2 or 3 times a year."

 

Researchers call these pure ultra-low frequency oscillations "pulsations continuous" (Pc). Pc waves have an energizing influence on particles in Earth's inner magnetosphere because they resonate with the natural motion of particles around the geomagnetic field. This, in turn, can supercharge the aurora borealis.

Some of the energy injected by Pc waves is being observed right now in Sweden. "The auroras are going crazy!" reports Chad Blakley of Lights over Lapland, who roared out on his snowmobile to photograph the display:

 

 

Sounds like our members living in the far North MIGHT be in for a real treat tonight.

Thanks for sharing,  I would love to see those lights sometime. .

 

The article was interesting in it's comparing solar wind to blowing across an opened bottle mouth,  the frequency that it made...
