    Questions about transits in Calgary

    When is the next ISS transit in Calgary?

    The next good transit near Calgary is the ISS crossing the Sun on Sat 10 Oct at 14:59:23.0 GMT-6 (20:59:23.0 UTC). Its centreline passes 102 km SW of central Calgary, and the strip is 15 km wide. It is 29° up in the SSW and the crossing lasts 1.02 s.

    Do I need to travel to see one from Calgary?

    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 102 km from central Calgary, so the strip's edge is 94 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.
