    Questions about transits in Perth

    When is the next ISS transit in Perth?

    The next good transit near Perth is the Envisat crossing the Sun on Sat 10 Oct at 15:15:44.8 GMT+8 (07:15:44.8 UTC). Its centreline passes 111 km E of central Perth, and the strip is 15 km wide. It is 38° up in the WNW and the crossing lasts 1.57 s.

    Do I need to travel to see one from Perth?

    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 111 km from central Perth, so the strip's edge is 103 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.
