I saw a double rainbow when I finally got out of the lab at 5:30pm. Yes, it's the real rainbow, not the icecream. It's dark half of the sky but the sky was shining from the west. There's also thunder and I was a little wet.

It's a sharp semi-circle, with violet in the bottom and red at the top. Then there's another but less sharp semi-circle rainbow above this sharp rainbow. The spectrum of the rainbow above is in reverse order of that of the rainbow below.

How come I didn't bring my camera. It's such a wonderful natural beauty.
