The Green Flash

During sunrise and during sunset, you're going through more atmosphere than usual. And so the higher frequencies of light get scattered more which is why sun rises and sunsets are red. Do you have an opinion on whether the green flash exists? Have you heard of that in terms of like there is a green flash just as it goes beyond the horizon? I feel like I've seen it too, but I didn't know if it was just sort of psychosomatic. It's also fascinating to think about the colors of everything else out there in the solar system.
