A Global Magnetic Anomaly Was Recorded Across the World From the U.S. to China and Antarctica on June 23rd – And That’s Very Weird During the Deepest Solar Minimum in a Century!


Lately, Earth’s magnetic field has been quiet. Very quiet. The sun is in the pits of what may turn out to be the deepest Solar Minimum in a century. Geomagnetic storms just aren’t happening.

But on June 23rd instruments in Preston, UK, picked up a magnetic anomaly… And the local magnetic field oscillated like a sine wave for more than 30 minutes. Totally weird, no?

There was indeed nothing shown on solar wind data from NOAA’s DSCOVR satellite. No uptick in the solar wind speed or other factors that might explain the disturbance.

A similar magnetic anomaly was detected in the Lofoten islands of Norway by Rob Stammes detected a similar anomaly on his magnetometer. “It was remarkable,” says Stammes. “Our magnetic field swung back and forth by about 1/3rd of a degree. I also detected ground currents with the same 10 minute period.

And similar electrical surge and magnetic anomaly was reported again from Norway beginning of this year (January 2020):

What happened?

Space physicists call this phenomenon a “pulsation continuous” or “Pc” for short.

Imagine blowing across a piece of paper, making it flutter with your breath. Solar wind can have a similar effect on magnetic fields.

Pc waves are essentially flutters propagating down the flanks of Earth’s magnetosphere excited by the breath of the sun.

During more active phases of the solar cycle, these flutters are easily lost in the noise of rambunctious geomagnetic activity. But during the extreme quiet of Solar Minimum, such waves can make themselves “heard” like a pin dropping in an silent room.

Earth’s magnetic field was so quiet on June 23rd, the ripple was heard all around the world. INTERMAGNET‘s global network of magnetic observatories picked up wave activity at the same time from Hawaii to China to the Arctic Circle. There’s even a hint of it in Antarctica (note Scott Base in the plot, above).

Pc waves are classified into 5 types depending on their period. The 10-minute wave on June 23rd falls into category Pc5.

Slow Pc5 waves have been linked to a loss of particles from the van Allen radiation belts. Energetic electrons surf these waves down into Earth’s atmosphere, where they dissipate harmlessly.

With Solar Minimum in full swing, there’s never been a better time to study these waves.
