When is the next ISS transit in London?
The next good transit near London is the ISS crossing the Sun on Sat 10 Oct at 14:14:08.6 BST (13:14:08.6 UTC). Its centreline passes 26 km NE of central London, and the strip is 16 km wide. It is 29° up in the SSW and the crossing lasts 1.04 s.
Do I need to travel to see one from London?
Usually a short way. The strip where a transit is visible is only a few to around 20 km wide, so it rarely crosses your own street. The next good one passes 26 km from central London, so the strip's edge is 18 km away.
Can I see a transit without a telescope?
The crossing lasts about a second and the station appears tiny, so a telescope or a long lens on a camera is needed to see its shape. Never look at the Sun without a certified ISO 12312-2 solar filter.
