    Questions about transits in Chicago

    When is the next ISS transit in Chicago?

    The next good transit near Chicago is the Envisat crossing the Sun on Sun 11 Oct at 15:16:20.5 GMT-5 (20:16:20.5 UTC). Its centreline passes 69 km W of central Chicago, and the strip is 21 km wide. It is 29° up in the SW and the crossing lasts 1.91 s.

    Do I need to travel to see one from Chicago?

    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 69 km from central Chicago, so the strip's edge is 58 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.
