    Questions about transits in Lisbon

    When is the next ISS transit in Lisbon?

    The next good transit near Lisbon is the ISS crossing the Sun on Tue 13 Oct at 15:05:58.4 WEST (14:05:58.4 UTC). Its centreline passes 56 km SW of central Lisbon, and the strip is 9.9 km wide. It is 38° up in the SSW and the crossing lasts 0.85 s.

    Do I need to travel to see one from Lisbon?

    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 56 km from central Lisbon, so the strip's edge is 51 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.
