Envisat

Ok, so I took my time, I had to register with a cracking site called www.heavens-above.com, but a couple of checks and I think I may have an answer. The image shows the track of Envisat, whatever that is, and seems a good match on timing and general area of the sky.

Will get a compass tomorrow to confirm my thoughts, and will try and find an explanation for the apparent changes in movement, but for now, I'm happy.

Dunbunkin', the name of my retirement cottage.
