Bizarre, Never-Seen-Before Activity Spotted From One of the Strongest Magnets in the Universe

Magnetars are a rare type of rotating neutron star with some of the most powerful magnetic fields in the Universe. Astronomers have detected only thirty of these objects in and around the Milky Way—most of them detected by X-ray telescopes following a high-energy outburst.

However, a handful of these magnetars have also been seen to emit radio pulses similar to pulsars—the less magnetic cousins of magnetars that produce beams of radio waves from their magnetic poles. Tracking how the pulses from these ‘radio-loud’ magnetars change over time offers a unique window into their evolution and geometry.

In March 2020, a new magnetar named Swift J1818.0-1607 (J1818 for short) was discovered after it emitted a bright X-ray burst. Rapid follow-up observations detected radio pulses originating from the magnetar. Curiously, the appearance of the radio pulses from J1818 were quite different to those seen from other radio-loud magnetars.

Most radio pulses from magnetars maintain a consistent brightness across a wide range of observing frequencies. However, the pulses from J1818 were much brighter at low frequencies than high frequencies – similar to what is seen in pulsars, another more common type of radio-emitting neutron star.

In order to better understand how J1818 would evolve over time, a team led by scientists from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) observed it eight times using the CSIRO Parkes radio telescope (also known as Murriyang) between May and October 2020.

A stereographic projection shows the movement of the magnetic (red) and geomagnetic (blue) poles in the northern hemisphere since 1900 (Thébault et al. Earth, Planets and Space)

Why worry about magnetic stuff in space??? We have enough magnetic stuff to worry about right here on earth.

If J1818 won’t play by the rules then de-platform it.

Funny how they state that they’ve never seen this before but they already know what it is.
Show Me!!!!

Stronger than the Alnico magnets I bought as a kid? C'mon, man! No way.

What does the blue solid line represent? The red dotted course?

Earth’s magnetic field is acting up and geologists don’t know why
Erratic motion of north magnetic pole forces experts to update model that aids global navigation.

Something strange is going on at the top of the world. Earth’s north magnetic pole has been skittering away from Canada and towards Siberia, driven by liquid iron sloshing within the planet’s core. The magnetic pole is moving so quickly that it has forced the world’s geomagnetism experts into a rare move.

The most recent version of the model came out in 2015 and was supposed to last until 2020 — but the magnetic field is changing so rapidly that researchers have to fix the model now. “The error is increasing all the time,” says Arnaud Chulliat, a geomagnetist at the University of Colorado Boulder and the National Oceanic and Atmospheric Administration’s (NOAA’s) National Centers for Environmental Information.

In the meantime, scientists are working to understand why the magnetic field is changing so dramatically. Geomagnetic pulses, like the one that happened in 2016, might be traced back to ‘hydromagnetic’ waves arising from deep in the core1. And the fast motion of the north magnetic pole could be linked to a high-speed jet of liquid iron beneath Canada2.

I’ve been predicting this since the early 1990’s. I explained this at a conference and everyone laughed. Hang on to your hats.

Question

Is there a dynamo effect upon the magnetosphere based upon the alignment of the earth’s core axis (magnetic pole) and the earth’s crust axis (geographic axis)?

Does an alignment of the axis cause a decrease in field strength?

Is this significant enough to allow an abnormal increase in solar radiation hitting earth?

Is this vulnerability increased if the sun hits solar max in reverse polarity to earth during polar axis alignment?

[tired&retired]

Could the variations in the magnetosphere cause the ice ages and major fluctuations in earth’s global temperature?

Stronger magnetosphere yields cold weather, weak yields warming.

Pole alignment yields weaker field yields global warming???

It’s called a magnetic excursion. Happens every 12k years or so. Lots of evidence that there is a correlation with the Sun. The magnetic excursions are usually followed by some sort of catastrophe. Google the Heinrich events and you’ll see they occur every 12,000 years or so. The last one being about 12,000 years ago.
The suspicious observers channel on you tube has a lot of info on whats going on. Lots of Sun related stuff thats above my head but the catastrophe stuff is pretty easy to understand.

Thanks for the references.

I researched this 30 years ago after I had an earthshattering vision of future events. It has unfolded exactly as I was shown but the timeline is distorted and is much longer. I expected what is happening now in the 1990’s.

It’s Trump’s fault.

Really good read on climate change influence factors.
