A PURE SIGN WAVE IN THE MAGNETOSPHERE: In a quiet room, you can hear a pin drop. Norwegian citizen scientist Rob Stammes just heard a pin drop on Earth’s magnetic field.
“It was very quiet when it happened,” says Stammes, who runs a space weather observatory in Lofoten, Norway. On Oct. 17th, his magnetometer was monitoring Earth’s magnetic field as it does every night, and the instrument’s needle had settled itself into a straight line, indicating very low geomagnetic activity. Suddenly, Earth’s magnetic field began to ring.
