Having seen this last night (or could it just have been Father Christmas) I just wondered whether, at an altitude of approx 160 miles, would it generate a contrail, or is it too high? A neighbour believes she took a photo of it today, at 0957 (timeline is right for a pass) but I wonder if it was a plane at 6 miles, or ISS AT 160? I know it's Christmas, but I'd love to prove her wrong!! Any ideas?

The iss is at 230 miles and does not leave contrails
You see the ISS due to sunlight reflecting off its solar panels.

Doubt you would have seen it during daylight.

If you go to

http://www.heavens-above.com

and choose somwhere near you or use your latitude and longitude you will get times when you can see it from your location. Always give it a few minutes either side of the stated time. What you will see will look like a fast moving star. Remember, negative numbers are bright eg. -1.5 is brighter than -0.5


To check for planes use FlightRadar24 - either their app or website.
No contrail from the ISS - too high. The folks on board would be in big trouble if there was. Its in freefall anyway so not jetted around. The ISS looks like a bright white star/planet, as bright as venus and doesnt twinkle. Moves silently and not quite as fast as a high alt plane would seem to. A small telescope will show the solar panels etc.
Needs to be in the atmosphere to have a contrail. simples. tch!
whatever, it's heavy cloud and pissing down here, so no chance of seeing it, at least no snow which boaty may now be getting.......
