Ethereal green "aurora curls" were photographed in the night sky over Iceland after a gust of solar wind vibrated Earth's magnetic shield like a plucked guitar string. The phenomenon is extremely rare.

A single streak of eerily-perfect, rippling green light recently wobbled through the night sky above Iceland, interrupting an otherwise typical aurora, stunning new photos show. The extremely rare phenomenon is the result of large waves vibrating in Earth's magnetic field that are triggered by solar particles slamming into our planet.
Jeff Dai, an astrophotographer and member of The World at Night (TWAN) project, spotted the zig-zagging light show above Kerid a crater lake in south Iceland on Jan. 16, Spaceweather.com reported. The unusual phenomenon, known as aurora curls, lasted for "several minutes" before disappearing completely, Dai wrote on Instagram.
Auroras are created when highly energetic particles from the sun bypass Earth's magnetic field, or magnetosphere, and excite molecules of gas, which give off colored light as a result. Normally, these dancing lights swirl randomly across the night sky with no definite shape or pattern.
Aurora curls are a rare, highly organized version of these lights caused by massive ripples in the magnetosphere, known as ultra-low frequency (ULF) waves. These magnetic tremors are most commonly triggered by a gust of radiation from the sun, known as solar wind, colliding with our planet's protective shield and can cause our atmosphere to "ring like a bell," according to Spaceweather.com.

A rare natural electrical phenomenon was recently captured in images of the night sky over Icelands 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.
Dais 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 Universitys Institute of Space Physics and Applied Technology, Dai learned that the phenomenon he managed to photograph occurs when the Earths 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 planets magnetosphere.

Very cool stuff.
