NASA has downloaded Trimethylaluminium (TMA)

According to NASA, which funded the mission, two rockets released Friday night Trimethylaluminum (TMA) and a barium/strontium mixture in the magnetosphere across Norway.
NASA has stated that “chemicals pose no danger to residents of the region.”

But what was the purpose of the experiment?

According to NASA, the experiment was to measure winds and currents in the ionosphere, an electrically charged layer of the terrestrial atmosphere where the Aurors appear. Specifically, researchers are interested in discovering how auroral energy can per voltage to the earth to affect the lower atmosphere.

Or was the experiment a bit more unpleasant? Perhaps the most exotic form of geophysical warfare is about tampering with the electrical behavior of the ionosphere.

The techniques for disrupting radio communications with “holes” in the ionosphere with nuclear explosions have been discussed for a long time. Similarly, they have proposals to open deadly windows in the ionosphere to get the short-wavelength ultraviolet radiation known to damage biological systems, cause human skin cancer, and crop damage.

What is new is the suggestion that the natural waveguide between the ionosphere and the earth can be used to dissipate low-frequency radiation (VLF) through it in such a way that it affects the electrical behavior of the brain activity of the individuals themselves.

Trimethyl aluminum

According to Wikipedia, an anomaly from the Norwegian spiral 2009 appeared in the night sky above Norway.
It was visible and photographed from northern Norway and Sweden.

Trimethyl aluminum (TMA) and a mixture of barium/strontium

The spiral consisted of a blue ray of light with a grayish spiral originating from its extremity.
The light can be seen throughout Trøndelag in the south and in all three northern counties that make up northern Norway and northern Sweden and last for 10 minutes.

According to the sources, it looked like a blue light coming from behind a mountain, staying in the air and starting to spiral outward.

A similar event, although less spectacular, had also occurred in Norway the month before.
Both incidents had visual features of the failed flights of Russian SLMM RSM-56 Bulava missiles, and the Russian Ministry of Defense said shortly after such an incident occurred on December 9.

Last night (April 5, 2019) NASA’s AZURE mission successfully launched 2 rocket rockets back to back from the Andøya Space Center in Norway.

They released clouds with glowing trackers in the upper atmosphere (background green is the real aurora) to study and track the flow of neutral and charged particles in the ionosphere. Each dot has a different height and notices that they migrate with different speeds and directions!
