Something unexpected happened in the soil of northern Norway on January 6, 2020.
Suddenly, electrical currents started flowing creating strong variations in both ground currents and the local magnetic field… Like a shockwave.
The magnetic shockwave was captured by sensors of the Polarlightcenter geophysical observatory in Lofoten around 7:30 p.m. UT.
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.
