A GLOBAL MAGNETIC ANOMALY:  On June 23rd, Earth’s quiet magnetic field was unexpectedly disturbed by a wave of magnetism that rippled around much of the globe. There was no solar storm or geomagnetic storm to cause the disturbance. So what was it?

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.

“That’s why I was so surprised on June 23rd when my instruments picked up a magnetic anomaly,” reports Stuart Green, who operates a research-grade magnetometer in his backyard in Preston UK.

“For more than 30 minutes, the local magnetic field oscillated like a sine wave.”

Green quickly checked solar wind data from NOAA’s DSCOVR satellite.

“There was nothing - no uptick in the solar wind speed or other factors that might explain the disturbance,” he says.

He wasn’t the only one who noticed. In the Lofoten islands of Norway, Rob Stammes detected a similar anomaly on his magnetometer. “It was remarkable,” he says.

“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.”

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.

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. Keep quiet … and stay tuned for more.

Inaccurate Virus Models Are Panicking Officials Into Ill-Advised Lockdowns

Misinformation is driving this mania. You have leftwing panicmongers like MSNBC’s O’Donnell predicting ‘millions’ will die if churches are ‘packed’ on Easter. Inaccurate Virus Models Are Panicking Officials Into Ill-Advised Lockdowns How a handful of Democratic activists created alarming, but bogus data sets to scare local and state officials into making rash, economy-killing mandates. By Madeline Osburn, The Federalist, March 25, 2020 As U.S. state and local officials halt the economy and quarantine their communities over the Wuhan virus crisis, one would hope our leaders were making such major decisions based on well-sourced data and statistical analysis. That is not the case. A scan of statements made by media, state governors, local leaders, county judges, and more show many relying on the same source, an online mapping tool called  COVID Act Now.  The website says it is “built to enable political leaders to quickly make decisions in their Coronavirus response i...

Covid-19: Day 87: Mar26th: Why Did Hundreds Of CEOs Resign Just Before The Virus? Millions of locusts cover streets in Oman: Fired Americans Send Unemployment Websites Crashing Down: US deaths top 1,000 as $2.2 trillion in virus aid approved.

Certain people made billions from 9/11, it looks like many more bosses were given a heads-up just before Covid-19 exploded! Why Did Hundreds Of CEOs Resign Just Before The World Started Going Absolutely Crazy? In the months prior to the most ferocious stock market crash in history and the eruption of the biggest public health crisis of our generation, we witnessed the biggest exodus of corporate CEOs that we have ever seen. And as you will see below, corporate insiders also sold off billions of dollars worth of shares in their own companies just before the stock market imploded. In life, timing can be everything, and sometimes people simply get lucky. But it does seem odd that so many among the corporate elite would be so exceedingly “lucky” all at the same time? One financial publication is using the phrase “the great CEO exodus” to describe the phenomenon that we have been witnessing. It all started last year when chief executives started resigning in numbers, unlike anything th...
