For background, I was on a tour coming back from Ballestas Islands just off of Peru, around 11:00 a.m., no rain (it’s a desert area), sky was partly cloudy. The phenomenon stayed a couple of minutes. As we progressed, the colours merged to a strand of amber.
Am Canadian. Have seen them. It’s more about altitude than lattitude.
Edit: Spend a little bit of every day looking at the sky. Day or night, it’s often magnificent.
