As I was walking in the streets of Lisbon, I looked up and saw straight above several streaks of light, some white and a strong green streak, almost looked like an Aurora, I suspect it was a reflection of city lights on ice crystals in the clouds above.
I took a long exposure photo with my phone.
After arriving home, the effect was still visible but blurrier.
The position of the streaks was similar to the citys main arteries. I know about this phenomena but Ive never seen this effect in the Zenith. It was an amazing sight to see.

That is a quite rarely seen phenomenon for such a southerly location. Halo pillar-like reflections from earthbound artificial light sources in ice crystals are rather commonly observed in arctic areas.
