White auroras are a rare and breathtaking phenomenon seen in high-latitude regions such as Finland, Norway, and Alaska. They occur when low-energy charged particles interact with oxygen atoms high in Earth’s atmosphere, producing a faint white glow.

Or they are something else
lol white aurorae are HYDROGEN
can be also argon and oxygen involved but the most important fact is white means big current in the atmosphere. the magnetosphere is weakening. the solar cycle is below cycle 23. the sun cycles have been declining for decades.
none of this is normal.
White can come from a blend of auroral colours. Faint auroras can also look colourless to our eyes in low light.
I’ve never seen these or heard of them.
Wow, very nice. Thanks for sharing. 👍
