I could see an odd colour in the sky last night at about 4am , just vague because it was cloudy. So I took a long exposure (60 second) shot.

I posted this on Threads and someone then told me it’s not possible to photograph an aurora through cloud? But I don’t know how thin or dense the cloud was and also my camera shake makes everything look extra blurry.

If this isn’t an aurora, (maybe reflected through gaps in cloud), what has caused this?
