We used to look out for this a few years ago but I haven't checked for some time now. As it happens, it's viewable tonight in the southwest tonight.
In Plymouth, at 22:03 for 6 minutes starting in the SW and heading to the E
and back again at 23:39, from the E and heading ENE.
With a clear sky, it's got to be a great chance to see it travel over.
You can check for other locations, and for other days this week, here: https://spotthestation.nasa.gov/
Then search for your city/town, if it doesn't reveal a blue marker, zoom out for find one close by. Click on that marker, then on 'View sighting opportunities'.
That'll guarantee cloud cover!
