The sun is at upper right and the contrail casts a shadow on the cloud below. The contrail moved towards the right. |
As the shadow drifted across me it briefly appeared to extend below the cloud forming a diffuse band. |
30 seconds later and the main shadow was well to the other side of the contrail and the lower shadow has gone. |

Just moments before the contrail shadow passed over me the shadow can be seen extending below the cloud. |
The shadow has already crossed over so it is now slightly more diffuse to the right of the main shadow. |
Seconds later and the lower shadow is already disappearing because I'm no longer looking along the shadow plane. |
