Circumzenithal Arc and Microlight


While I was photographing a bright circumzenithal arc I could hear this microlight approaching, so I was ready when it flew directly in front of the arc. In the summer months these 'lawnmowers with wings' can be a noisy nuisance, but this one was forgiven.

I was lucky in that not only was the arc bright at the right time but also that the microlight passed through this relatively small patch of sky as seen from my position.

These three images, taken 20 seconds apart, show how quickly the cloud moved through and the appearance of the arc changed.
