Was woken around 3am by an aurora red alert.
Checked outside: clear skies, so took some photos to the north.
Am 99% certain that the red & green coloured rainbows in this picture are not the aurora, but rather artefacts of the iPhone’s night mode stacking.
Make that 99.99% certain.
Trust me. I did the control experiment looking south & saw the same 🤷♂️🙂

1. A night mode image of a clear sky with many stars and hints of the Milky Way. There is a hillside and some houses at the bottom and the silhouette of a building to the right. There are some faint coloured rainbow arcs across the sky which are not the aurora.
