On January 6, 2020, a sudden and unexplained electricity surge and magnetic anomaly took place in northern Norway. Picture Polarlightcenter geophysical observatory via Space weather gallery
The magnetic shockwave was captured by sensors of the Polarlightcenter geophysical observatory in Lofoten.
The scientist in charge recalls the strange phenomenon: “It seemed to be some kind of shockwave. My instruments detected a sudden, strong variation in both ground currents and our local magnetic field. It really was a surprise.“
15 minutes before the electrical surge in Norway, NASA’s ACE spacecraft recorded anomalies in the interplanetary magnetic field (IMF) near Earth and a 5-time increase in the solar wind density.

Scientists believe the most plausible explanation for those weird phenomena is that Earth may have crossed through a fold in the heliospheric current sheet, as such crossings can cause these kind of effects.
And to top it all, the current flowing through the ground somehow electrified the sky with surprisingly vivid auroras.
