If the sun angle is low enough, I like to take a few flare photos for experimentation. The sun hitting the lens directly can cause all sorts of artsy effects, most notably the little colored circles, or in this case - some fun haloing and color aberation.
It was 75F and sunny in San Francisco today, a perfect day to have 2 photo shoots. Plus dog walking twice... I spent most of my daylight hours outside, and I was perfectly delighted. Why be inside watching Super Bowl when there's warm sunshiney weather in February? Summer in SF isn't this nice.
