Weird: Out of Nowhere, Something Just Rocked Earth’s Magnetic Field

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.

If that pin was made of steel, maybe dropping it causes a ripple in the local magnetic field. Just saying … They say in Preston (20 miles down the road) of people placing (small) bets on horses that they are ‘having a flutter’. To me it now has a whole new meaning.

The most likely reason is that the Earth’s magnetosphere was swiped by a sharp transition in the heleispheric current polarity.

These are common regular low intensity events, normally masked by various solar magnetic activity of a grater magnitude. Nothing much to be excited about.

I agree, Vuk. The solar magnetic field change was from Toward to Away at 12:55 on June 23rd 2020.

Okay, okay, I admit it: it’s my fault.

I was trying to pick up a long range radio signal last week, something like Moscow or maybe Baltimore or Rekjavik, because the heaviside layers were elevated enough to allow it. Everything was going smoothly until my cat found the antenna wire and moved it. Disrupted everything, and started that mag wave ball rolling.

Sorry about that. I’ve scolded her, but you know cats: they yawn, look at you like you’re asking them to eat lettuce instead of FF Chicken, and go right back to whatever they were doing. I had to put her outside the bathroom and shut the door. She’s still mad at me, too.

is this the magnetic field equivalent to stall flutter in fluid dynamics? Stall flutter was the cause of the Tacoma bridge collapse. Air flow from a constant wind passing the towers produced vortexes that then were shed at regular periods, imparting a force on the tower. The velocity of the wind was just right to produce shedding at the resonant frequency of the bridge.

This article is making a mountain of a signal out of a molehill of pulses. It certainly did not ‘rock’ the Earth’s magnetism, as the title implies: “Weird: Out of Nowhere, Something Just Rocked Earth’s Magnetic Field”
And it really has nothing to do with Earth’s currently quiet magnetic field:
“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.”

The sunspot count is currently zero (because we are in a solar minimum between cycles 24 and 25). But the solar flux index (SFI) currently stands about 68, which is about 4 index points above the lowest flux index recorded during the last solar minimum (between cycles 23 and 24). Still a way to go before we can claim ‘deepest’ minimum:
https://wattsupwiththat.com/2008/07/16/sun-in-deep-slumber-107-solar-flux-hits-record-low-value/

Also, I would like to point out that it is not the strength per se of the Sun’s magnetic field that causes geomagnetic storms. Geomag storms are defined by the change (“disturbance”) in the Earth’s magnetic field caused by changes in ring currents, induced by increased flow of solar wind protons and electrons.

A geomagnetic storm is defined by changes in the Dst (disturbance – storm time) index. The Dst index estimates the globally averaged change of the horizontal component of the Earth’s magnetic field at the magnetic equator based on measurements from a few magnetometer stations. Dst is computed once per hour and reported in near-real-time. During quiet times, Dst is between +20 and −20 nano-Tesla (nT).
A geomagnetic storm has three phases: initial, main and recovery. The initial phase is characterized by Dst (or its one-minute component SYM-H) increasing by 20 to 50 nT in tens of minutes. The initial phase is also referred to as a storm sudden commencement (SSC). However, not all geomagnetic storms have an initial phase and not all sudden increases in Dst or SYM-H are followed by a geomagnetic storm. The main phase of a geomagnetic storm is defined by Dst decreasing to less than −50 nT. The selection of −50 nT to define a storm is somewhat arbitrary. The minimum value during a storm will be between −50 and approximately −600 nT. The duration of the main phase is typically 2–8 hours. The recovery phase is when Dst changes from its minimum value to its quiet time value. The recovery phase may last as short as 8 hours or as long as 7 days.
The size of a geomagnetic storm is classified as moderate (−50 nT > minimum of Dst > −100 nT), intense (−100 nT > minimum Dst > −250 nT) or super-storm (minimum of Dst < −250 nT).

https://en.wikipedia.org/wiki/Geomagnetic_storm

So, the increased ring currents create their own magnetic field, which _opposes_ the Earth’s magnetic field. That is why storms are defined by negative disturbances.

Now back to the pulsations observed by the two amateur observers (Green and Stammes) on 23 June 0600-0700 UTC. I see nothing remarkable about these signals, except that they are very tiny. If we zoom in to that exact hour, I think we can see them here on this USGS plot, which lists the USGS stations sorted by descending Northern latitude (because the disturbances tend to increase towards the poles).

But you can see tiny sinusoidal pulses like these virtually everywhere, between the big disturbances. (Look at 12 June around 0800 UTC for example). What is so special about the 23 June pulses?

Channel “F” (total magnetic field) [Note changes in field at mid latitudes are much less than -50nt, so way below ‘storm’ grade disturbances]
https://geomag.usgs.gov/plots/?scale=10&endTime=2020-06-23T07:00:00.000Z&startTime=2020-06-23T06:00:00.000Z&timeRangeType=custom&channels=F
Channel “Y” (north component, which is smaller, but makes pulsation look relatively bigger)
https://geomag.usgs.gov/plots/?scale=10&endTime=2020-06-23T23:00:00.000Z&startTime=2020-06-23T00:00:00.000Z&timeRangeType=custom&channels=Y

But if you zoom out, and look at magnetic ‘disturbances’, over the whole month of June, you can see numerous events exceeding negative a hundred or so nano-tesla’s. I would say that is fairly ‘noisy’ for disturbance plots during a solar minimum. The pulsations were about 10nt-20nt, so completely swamped by this activity.
https://geomag.usgs.gov/plots/?channels=MDT&scale=Auto&timeRangeType=custom&channel=F&endTime=2020-06-26T20:30:00.000Z&startTime=2020-06-01T20:30:00.000Z

What about the current F10.7 cm flux staying as low as it is for this extra length of time? … https://www.spaceweatherlive.com/en/solar-activity/solar-cycle

Currently it looks to be running 6 months longer at this low point as compared to the last long minimum. It has yet to show a move towards rising off of the bottom. I am not familiar enough with previous minima to know how to assess that, but it looks like it is going to stay low for awhile longer.

“… staying as low as it is for this extra length of time?”

Solar magnetic activity is measured by intensity (or lack) of solar flux. The time span of activity further characterizes the nature of this activity, but IMHO does not really measure the intensity of activity.

So the previous solar minimum will be “deeper” if this one never descends down to ~64SFI, which is the theoretical minimum SFI.

Here is something of interest to this post. A powerful 7.4 quake struck southern Mexico at 15:30 UTC on the 23rd. That would be 9 hours after the magnetic disturbance. In 4 days from now on the 30th the 7 planet alignment will be at peak alignment. Earth and Mercury will be in conjunction. Venus and Saturn will be in conjunction, and Jupiter will be very close to conjunction with Pluto. … https://mgvez.github.io/jsorrery/

In an odd solar cycle. the Sun’s magnetic field is pointing south which means it can cancel part of the Earth’s magnetic field at the point of contact – creating a crack in the Earth’s int the magnetic field which allow the solar wind to enter into the Earth’s atmosphere rattling our magnetic cage.

No such thing as a “wave of magnetism”

You cant uncouple magnetic influence from it’s source. Any claim to the contrary is pseudo science

“You cant uncouple magnetic influence from it’s source.”

Actually it can; have you ever heard of “IMF”? (hint: not ‘impossible-mission force’)

IMF is the interplanetary magnetic field, whose source is the Sun.

The Sun’s magnetic field isn’t confined to the immediate vicinity of our star. The solar wind carries it throughout the solar system. Out among the planets we call the Sun’s magnetic field the “Interplanetary Magnetic Field” or “IMF.” Because the Sun rotates (once every 27 days) the IMF has a spiral shape — named the “Parker spiral” after the scientist who first described it.

https://spaceweather.com/glossary/imf.html

Here is a 3D rendering of the IMF, based on an old drawing made by Leif Svalgaard in the early 1970’s. [Leif was a pioneer in this area of solar research]

re: “You cant uncouple magnetic influence from it’s source.”

Statically, yes, BUT even a ‘static’ source had a beginning (OR, if it is physically moved), so in the long run it is changing, which is the basis for “radiating” a wave, an EM or electromagnetic wave.

I do it everyday via a dipole (or loop) antenna, and so do you via a smart/i phone or a WiFi client.
