Yep - with excellent timing, the ISS will appear several times over the UK today and tomorrow, and will appear, in some cases, "incredibly bright".
The station will make its first -and brightest - pass over the UK at 5.20pm. If you miss that, it'll pass over - fainter this time - at 6.58pm, And if you miss it, it'll pass over several times during Christmas Day. An excellent time to explain about timezones, perhaps...?
Want to inject a bit of festive magic? Here are all the times Santa/the ISS will pass over the UK during the festive period. You can track its progress here.
