I just saw ISS pass overhead while still reasonably light - looked away then looked again and there did appear to be something very close behind it - stray reflection on me specs perhaps? I nipped inside and upstairs with me bins for a closer look, by which time it was halfway across Germany, and hard to keep still enough to see clearly. I'll try and take another look on its next pass.
Edit: nothing noticeable on the next pass though there is some very thin patchy cloud about which dimmed it a bit.
