Last Thursday there was a beautiful sunset, and as I admired it from my tall building in downtown Berkeley, I noticed there was a light drizzle in the sun's glow. I dashed to the roof, and indeed I was correct to expect something pretty. I didn't, however, expect anything quite so good as this:

A perfect double rainbow, the first rainbow I've ever seen in Berkeley. And just inside the inner rainbow, without any space, there was the hint of a
third rainbow. I'm not sure what would cause that, but I'm pretty sure it was really there.
Glorious.
