Rainbow - 7 May 2010

This May is full of raining. However, mathematical simulations had predicted a gap among the clouds in the middle of this night, so I decided to go to my small observatory. During preparations (for night observing and taking photos) it was pouring down. It looked awful and I was not sure whether simulation results were right or not. Suddenly, the Sun showed its face and created a nice rainbow. After that the weather began to change and, for my pleasure, the predicted gap between two low pressure areas arrived.
