Earth’s magnetic field was so quiet on June 23rd, “the ripple†was heard all around the world. “For more than 30 minutes, the local magnetic field oscillated like a sine wave,†reports Stuart Green, based in the UK.
Lately, Earth’s magnetic field has been quiet. Very quiet. The Sun is in the pits of the deepest Solar Minimum in more than a century. Geomagnetic storms just aren’t happening (spaceweather.com).
“That’s why I was so surprised on June 23rd when my instruments picked up a magnetic anomaly,†reports Stuart Green, who operates a research-grade magnetometer in his backyard in Preston UK.
“For more than 30 minutes, the local magnetic field oscillated like a sine wave,†says Green:
“Our magnetic field swung back and forth by about 1/3rd of a degree. I also detected ground currents with the same 10 minute period.â€
So what happened?
Space physicists call this phenomenon a “pulsation continuous†or “Pc†for short, explains Dr Tony Phillips at spaceweather.com.
