    Questions about transits in Seattle

    When is the next ISS transit in Seattle?

    The next good transit near Seattle is the ISS crossing the Sun on Mon 12 Oct at 14:00:46.0 GMT-7 (21:00:46.0 UTC). Its centreline passes 44 km SW of central Seattle, and the strip is 12 km wide. It is 33° up in the SSW and the crossing lasts 0.96 s.

    Do I need to travel to see one from Seattle?

    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 44 km from central Seattle, so the strip's edge is 38 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.
