Today's photo shows traces of at least seven vapour trails in the same area of sky. (If you check the larger view you will see a small one, just left of centre, in the process of being made!)
The view is looking across the Tame Valley in Mossley, near Ashton, towards the Pennine moors. Most of the vapour trails in the picture have been made by planes flying from east to west across Northern England, probably originating from Europe. The trail visible in the top right corner is being made by a plane heading north-westwards from London towards North America.
Occasionally, when there is a blue sky with lots of trails and I have nothing else better to do, I zoom in on the map on this fascinating site to see where the planes making the trails have come from and where they are going.
What could be more appropriate for Sky Watch?

Sky Watch is a regular weekly feature on this photo blog. It links with websites all over the world with the general theme each week of looking upwards. Please take the opportunity to visit some of these other sites. I hope some new visitors have found their way here today, watching the skies!
