MICAH HANKS·JANUARY 31, 2024
A rare natural electrical phenomenon was recently captured in images of the night sky over Iceland’s Kerid Crater.
Photographer Jeff Dai, a resident of China who is currently traveling in Iceland, observed an unusual rippling motion within the green bands of the aurora borealis on January 16, 2024.
The phenomenon sparked his curiosity, and Dai went for his camera.
“I captured this rare image of ‘aurora curls’,” Dai said. “They rippled across the zenith for several minutes.”
Dai’s amazing imagery was subsequently featured at spaceweather.com, the long-running online provider of information about the Sun-Earth environment.
Reaching out to Xing-Yu Li, a scientist with Peking University’s Institute of Space Physics and Applied Technology, Dai learned that the phenomenon he managed to photograph occurs when the Earth’s magnetic field vibrates, the wavelengths of which become visible as “ripples” during auroral displays like the one he photographed earlier this month.
The photographs reveal a rare physical manifestation of the phenomenon, which is normally only viewed in data collected by instrumentation used to monitor our planet’s magnetosphere.
