    Questions about transits in San Francisco

    When is the next ISS transit in San Francisco?

    The next good transit near San Francisco is the ISS crossing the Sun on Fri 9 Oct at 16:23:25.3 GMT-7 (23:23:25.3 UTC). Central San Francisco is inside its visible strip. It is 25° up in the WSW and the crossing lasts 0.93 s.

    Do I need to travel to see one from San Francisco?

    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 over central San Francisco itself.

    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.
