South Atlantic Magnetic Field Anomaly

[axj]

Hi everyone,

Aside from satellites having problems in the South Atlantic and South America region due to the weaker magnetic field there letting through more of the solar wind and cosmic particles, are there also any positive or negative effects on the people living in that area? Maybe less protection against radiation or even some deeper effects on people? I happen to live right at its center in Paraguay.

The C's mentioned that UFOs avoid the area, so I guess that can be counted among the positive effects:

(L) Isn't there some place in the South Atlantic where the Earth's crust is very thin or something, like an opening or something there? Is that related in any way?

A: Yes

Q: (Andromeda) There's also supposed to be, I think, an anomaly in the Earth's electromagnetic field in that area, too.

A: Yes

Q: (L) Does it have anything to do with UFOs and underground bases?

A: No. They avoid the area.

Apparently this magnetic anomaly has been appearing and disappearing for a long time. It is moving around and now maybe splitting into two:

While there's much scientists still don't fully understand about the anomaly and its implications, new insights are continually shedding light on this strange phenomenon.

For example, one study led by NASA heliophysicist Ashley Greeley in 2016 revealed the SAA slowly drifts around, which was confirmed by subsequent tracking from CubeSats in research published in 2021.

It's not just moving, however. Even more remarkably, the phenomenon seems to be in the process of splitting in two, with researchers in 2020 discovering that the SAA appeared to be dividing into two distinct cells, each representing a separate center of minimum magnetic intensity within the greater anomaly.

Just what that means for the future of the SAA remains unknown, but in any case, there's evidence to suggest that the anomaly is not a new appearance.

A study published in July 2020 suggested the phenomenon is not a freak event of recent times, but a recurrent magnetic event that may have affected Earth since as far back as 11 million years ago.

If so, that could signal that the South Atlantic Anomaly is not a trigger or precursor to the entire planet's magnetic field flipping, which is something that actually happens, if not for hundreds of thousands of years at a time.

NASA is watching a vast, growing anomaly in Earth's Magnetic Field

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest Africa. This vast, developing phenomenon, called...

( hm , Plenty of window fallers in South America though , perhaps , afaik , more so than any other area ? local conditions there affect trans-density tech ? thus bases and ufo's are bad idea in the area ? )

Also the Atacama desert portal is located in the affected area.

Brazil is somewhat of a UFO and abduction hot spot though (see session 27/04/24), so perhaps it's only the central part of the Anomaly that UFOs avoid, where the affects are most intense.

Before any discussions that might cause allarming states of mind, the place to start learning about the Earth magnetic field is:

There was a recent study that measured radiation on a flight at 13km altitude within the South Atlantic Magnetic Anomaly and it found that there are no increased levels of ionizing radiation. Apparently the Van Allen belts come closer to Earth in that location and increase radiation levels only at altitudes of about 200km and above - which does affect satellites.

Though I do wonder how there can be no increase in solar and cosmic radiation in an area that has a much weaker magnetic field. Compared to the maximum field strength south of Australia, it is less than a third of that in the center of South America.

Another recent study predicts that the field strength will decrease somewhat further in the center of the anomaly by 2030 and that it may split further into two:

It's explained in details in the article.

Going rather fast through it, noticed the statement that for particle energies studied which results were presented in the article, something called atmospheric shielding plays more dominant role than so called geomagnetic shielding, thus leading to almost no difference in cosmic radiation flux on that altitude and for those energies with respect to the strength or the magnitude of the Earth's local magnetic field.
FWIW.
